Computer Shuts Down Automatically


My system, while running, would power off itself suddenly, and when i try to power it on again, it would not start and gives me a beep and then a small beep, along with the code 8. 3. However, if i wait like 5 to 10 mintues and then try to turn it on, it starts. From the manual:

Computer Reboots Automatically When Start Any Games

I'm having problems with my computer. If i start aim or rthdribl or any games, my computer reboots automatically. I tried disabling the reboot on error for windows, but it restarts and leads me to some blue screen. I've also tried booting in safe mode, and things seem to work in safe mode. So now i really don't know what's the problem.

Computer Just Shuts Off

A couple hours ago, i tap the front of the case with my foot, and everything just shuts off. I tried turning it back on and nothing happened. So i turned the power supply off and back on and tried again. This time, it tried to start and then immediately shutoff again. The power supply has a blue light in it and that goes out immediately as well. I can see 2 yellow lights on the motherboard are lit when the power supply is turned on. Do you think my power supply blew or is it something else? Any way i can test?

Computer Shuts Off After Startup

I just put together a new comp and unfortunately when i go to start it, it stays on for about a second and then shuts off, it only stays on long enough for the lights to flash and the fans to move just a bit, then it shuts down. I have been looking at different troubleshooting pages and they all have given me different answers to my prob, a few said pcu, some said motherboard, some said power supply, and one said memory. I wanted to know if anyone can give me an informed opinion on what might be causing the problem.

Computer Shuts Down During Memtest

My comp was suddenly shutting off during movies, music and internet browsing. It gen didn't shut off while standing still. I used the dell os cd to erase the partition and format ntfs (reg, not quick). During the menu's before the formatting and during the formatting, it continue'd to shut off. Now i don't have an os. On another comp, i burned two cds, one is window mem test and the other is memtest. The computer passed the windows mem test on all 11 counts of the adv scan. It keep restarting during the other cd, with memtest. Neither memory testers show an error while they are running. Both are run in default mode, as configured when i burned the isos the their cds. I ran the built-in diag tool in the bios, but it could only run half the tests, because the diag utilies on the hd are erased. I don't have the drivers and utilities cd that it asks for. Is this a memory prob, power supply, or what? I don't really have money to take to a repair shop or buy parts without knowing the prob. Let me know if you need any more info.

Computer Just Shuts Down Completely

Ok i have a computer never had a problem since i've had it i've always kept it updated . With new hardware and software. But now all of a sudden i'm on the internet or playing a game . Even watching tv and it just shuts down completely! . I thought maybe it was a virus so i backed up all my files, reformatted the computer, and re-done the windows. Still shutting down. Do you know what this could possibly be. My computer doesn't get hot. I got a fairly new power supply. But i've been using the same surge protector. Its a small one. But i've alwayz had that one since i got the computer. Someone at walmart thinks i need to get a new surge protector . The real big one. With the cable plug-ins on it for the tv.

Booting From Cd Shuts Off The Computer

Whenever i boot from my windows xp pro cd to reinstall the os it shuts off the computer completely at a certain point. I'm not sure if it is time related, but it shuts off right around the screen that it asks where to install xp. However, ubuntu 7 and windows vista are fine. They install and startup without a hitch. So what's the deal with xp? Could it perhaps be a problem with my cd or is it something else? The computer original ran xp back when i bought it in november 2006. I've seen this problem across the net but none seemed to propose an answer. I don't really think it would be a hardware problem if xp is the only one that has done this. Please note, this is not the first time i have reinstalled xp (i have installed it before successfully, this is the very first time i have had problems like this).

Computer Shuts Off Unexpectedly

So, this just started happening the other day, for no reason what so ever that i can see my computer just shut off. Not a shutdown sequence or anything like that, just flat out power-off like someone pulled the plug. Thought at first maybe a short power outage as we have been having them recently here, and it seems my ups backup is dead because it's been doing nothing to keep the comps up when the power goes out. I immediatly realized though, that not a single thing in the room other than the computer turned off. The other comp next to me was still on, lamp was still on, monitors were still on (though blank now). The problem keeps coming up now too, if i try and do anything with my computer other than just general email/programming/play some mp3s, it's likely to turn off, especially if i fire up any game like world of warcraft or black and white 2. At this point, i've determined it's likely either 1) the graphics card is over heating and causing the computer to power down or 2) my power supply has somehow become unstable and likes to shutoff if it's getting stressed or something. Idea #1 i tested by installing a temperature monitor and watching the temp. It's running at around 70c, sometimes getting up to about 76-78c. It's an nvidia 8800gtx card and from what i've seen searching about it, these temperatures are considered fairly normal, and i shouldn't have a problem unless i start seeing 85c+ which i never have. None the less, i'm still not entirely sure that the card isn't the problem since the power-off only seems to occur when it's being worked by a game, and the temp hits the mid-70s. For idea #2 i don't have any idea what i can do to test this. I have no backup power supply i could swap with which will work with this system (sata connectors, the gtx's power connectors, etc) otherwise i'd do that and see if the problem goes away. Is there any way i might be able to some how test this power supply without having to spend a lot of (preferably no, as i'm unemployed atm) money?

Lastly, any other ideas for things to check? According to the temperature monitor software my cpu is running at a nice cool 45c pretty much all times, and it's "system temperature" is 40c almost consistently. I'm pretty sure it's not the cpu that's overheating or causing a problem.

Computer Shuts Itself Off After 10 Seconds

When i turn on the power button the fans, leds, and hard drive turn on, but nothing appears on the screen. Then, 10 seconds later the computer shuts itself off. All this while no beeps come from the speaker. I've tried to reset the cmos with no resolution. My next step was removing all the peripherals, including the video card, but the symptoms remain exactly the same, in that it shuts off after 10 seconds. I removed the cpu and it doesn't smell burnt at all. I should add that there is a 5 month old antec power supply (i believe around 500 watts). So i'm going to assume its not the power supply. My question is weather the problem lies in the cpu or motherboard, or what other suggestions or help you guys may have.

Computer Shuts Down Unexpectedly

The computer shuts down only when i am really dogging it. For instance, yesterday, i had photoshop/unreal dev kit/web browser/messenger/movie tut/documentation all running on windows 7 and was using close to 3gb of memory and had just opened the unreal dev test mode and after about 3 minutes of traveling around to diagnose my map, it shut down. I was monitoring the temperatures as i was fully aware i had a lot going on and was definitely pushing it as hard as i could. Video showed about 75oc (i've called evga and they claim this is right about where it should be at peak temperature); my core was at about 56-57oc (again, i've called this in and amd claims that's about perfect at peak); and my general system temperature was about 53oc and suddenly, poof, the computer went off. The board didn't seem to receive any damage and came right back on and ran without any complaints, it was just that it seemed to say "i have had enough, i'm going down". I don't see any event logs in windows event viewer outside unexpected power outage, so i'm assuming it was delegated by the board, not windows. I have run prime95 for 24 hours to make sure that the processor isn't having trouble, and i ran 3dmark for 6 hours to make sure it wasn't video trouble and neither item alone pops the computer. Reading around, i don't believe i'm using over 450w-500w of power, and have a 700w power supply, that wattage calculation came from a wattage calculator and i tried to get at least 200 over the suggested amount. How can i figure out what is shutting down this dang computer!? Any suggestions? Should i just buy a second power supply and try it? Is 700w grossly underpowered for this kind of setup?

I'm going in for another prime95 test this weekend in fear that the board got damaged again. Does anyone have any other applications i should use to test what is causing this?

Computer Powers Then Shuts Down

I have a problem with an older computer (98-99) i turn it on, and it starts to turn on, and then as soon as it starts to load a little bit it turns off, the monitor stays on though. I have tried putting in the recovery disk but the computer turns off before i get to start formatting, does anyone know what it could be? I have tried plugging it in different outlets and nothing changes. Is it the power supply?

Computer Powers Up Shuts Down

The machine i'm running is listed below. I've had it for a few months, and today, when i tried turning it on, it would shut off within a second or two of turning it on. No post, no nothing. I tried unplugging the ps, because i read online that that sometimes solves similar problems people were having, but no luck. Before anyone asks, i installed an hd 3850 a few weeks ago, and that's the only hardware change. I think it could be the bios, but i've never had problems when i upgraded it when i built the machine.

Computer Shuts Down Restarts

For the past few weeks my computer has been shutting down on its own, the thing is sometimes it restarts right away and other times it could be an hour or two it will just boot back up on its own. I have tried everything i could think of i swapped the power supply with another one i had and same problem, took my video card out and tired another still same problem. My processor rarely ever runs hotter than 35c. I get no errors from windows. I reformatted my windows still same problem. I tried different ram still same problem. When my computer works like it is right now it runs perfect, the thing is it could shut down any second, or it could shut down two hours from now. Any help would be great i'm totally stumped.

Computer Freezes Shuts Down

I have had this problem that has got worse over the past week. When i first boot up i seem too get about 10 mins worth, then the screen freezes and then shuts itself down. I have trouble restarting, so i switch off completely. Then 5 mins later i turn back on and it seems to be fine. Until the next time. It happens the same again. I have a new case and fan so there is nothing wrong with that or power supply. I regular defrag and do a spy-ware and anti virus check. I'm running out of ideas, so can any one help.

Computer Shuts Down After Start Up

I have been working on this problem for the last 5 days and can't think of anything else to try. My computer when you get to the windows loading screen will shut down, but it can load into safe mode. After i load safe mode i am able to restart and load normal mode and i get to desktop for about 2 or so minutes then shuts down again. It is not a heat problem, i have checked the heat and all the fans are spinning. If anyone has any ideas?

Computer Shuts Down During Post

I built a computer for a friend of mine 2-3 weeks ago, and had it up and running with no problems. I thoroughly benchmarked and stress tested it. Once i was satisfied i packed it up and shipped it to my cousin. He just received it yesterday, hooked everything up, and the machine would turn on for 10 seconds, then just shut off. During this time, the fans and everything spins, so it doesn't seem to be insufficient power. After walking him through some steps over the phone, its seems that the rtc jumper was on the 'clear' pins, and not the 'default'. How that happened during shipping, i don't have a clue (maybe i should play the lottery with odds like that). After putting them onto the right pins, the machine at-least showed some signs of life, by starting the bootup sequence, but then shut itself down. Each time it shuts down and you start it back up again it seems to turn itself off sooner than the first time, but after letting it sit for a while it will stay on for 10-20 seconds, and then shut down again. It does not stay on long enough for you to be able to enter the bios. At the moment it looks like he will have to ship it back to me to figure out whats going on. Does anyone have any idea or anything as to what the cause/solution might be?

Computer Shuts Down While Booting

My desktop is about 4 years old. A friend had built it himself, but was no longer using it about 2 years ago. I have an abit bw7-raid motherboard:

http://www.Abit-usa.com/products/mb/techspec.php?Categories=1&model=73

I have a gigabyte of ram, a seagate scsi hd, among other things. I got home one night (may be 3 weeks ago) & discovered that there was a power outage. The desktop was completely shut down. My desktop is connected to a surge protector, but who knows, may be a power surge got to it. I hit the power button & the machine booted up fine. Anyways. About a week later, i came home to find the desktop completely shut down. There were no signs of another power outage. I turned the desktop back on, but it had shut itself off again in the middle of the night. And that's when all the trouble started. The next morning. And ever since then, i keep having to hit the power button multiple times (anywhere b/n once to over a dozen times) before the desktop would boot up properly. Usually, the machine shuts itself down completely w/in 5 seconds after i hit the power button to turn it back on. No weird beeping patterns on the initial boot up. At first, i thought it was a psu problem. I went out & got a new psu, a masterpower 350watt atx from compusa. Unfortunately, the new psu didn't solve the problem. Exact same problem (shutting down completely w/in 5 seconds) kept happening. I've since shoved the old psu back in & returned the new one. I also got a can of compressed air & "dusted" out the dust bunnies (a suggestion i saw in another thread). The computer actually booted up properly after i "dusted" out the insides (this was after about a dozen failed attempts), but it then shut itself off about 12 hours later. I've also tugged on the wires & boards after the computer boots up properly, but can't seem to get it to shut down while doing that (another suggestion from another thread). Lately, i've been messing w/it more. Before, the desktop would stay on (after repeated button pushing) for about 12 hours before it would shut itself down. But now. It will stay on for maybe 10 minutes or so. Sometimes 30 if i'm lucky. Most of the time, any folders or applications i have open would simply close & the computer would simply shut down completely. I have seen it. Hmm. "Properly" shut itself down (for lack of better words) twice. One time, the computer got to the log in screen during boot up. When suddenly, it said "windows is shutting down". I stared at the screen & a few seconds later, the computer had shut itself down. Another time, i was chatting on wow. When suddenly wow closed & the computer said "windows is shutting down" a few seconds later, fall down & go boom. I tried looking for damaged capacitors (another suggestion i saw in yet another thread). I haven't had time to yank everything out so as to look more thoroughly, however. I will try that next week after my research paper is done. Hmm. What else. Oh! Under cmos setup, (not sure of the exact wording here) the cpu heat warning, cpu heat shutdown, and cpu fan warning were all already "disabled. " All my fans are working, by the way (including the cpu fan). I even put more. What's it called. Cpu grease (?) On the cpu/heatsink (i was grasping at straws. Hehe). But the problem persists. Well. I know how to put computers together (an amateur at it, though), but i am not very good at troubleshooting hardware. Oh, i don't know if it matters, but a while back, i was having problems & it turned out to be a bad ram chip (used memtest to isolate the problem back then). I've since replaced that bad ram chip.

Switching On Computer, But After Three Seconds It Shuts Down

I press the start button on my computer (from cold) and the computer begins to start up - the hard-drive light comes on and the fans start - but then after just something like three seconds it shuts down again. If i press the start button immediately after the computer remains dead - i seem to need to disconnect the mains supply at the house power-point (i.e. Pull the plug out the wall), wait about 15 seconds or so and then try again. Sometimes the computer will start normally first time, sometimes i have to repeat the above procedure half-a-dozen times. Once running there is no problem - no power shutdowns whatsoever. I'm using debian linux incidentally but am not sure whether the problem is anything as "far in" as the motherboard let alone the software - though something is detecting the power applied to the computer and capable of timing its presence to some extent at least.

Computer Boots For 5 Seconds, Then Shuts Down

The pc was auto shutting down for a week or so, it would bring up the standby, turn off, restart screen option then shut down. About a week later it completely shut down. You can't boot it anymore. It will act like it's booting up but then shut down after 5 seconds. No activity on the screen either. No option to goto bios. It just shuts down before it gets to the first screen. The next night i go there to change the power supply. I change it with another 250w that i have from home and still, no go. So i start thinking it could be a ram problem. Went get some chips from the car and changed them, still no go. I didn't think it would be hdd, fdd, cd/dvd problem but i unplugged them anyways and still. Boot for 5 seconds then shut down. Nothing connected but a stick of ram and the power supply.

Computer Shuts Down At Windows Login

I finally got my motherboard and vid card back from rma and bought a 520w vantec stealth psu. I hooked everything back up put my processor in. The comp booted up i went to bios to reset up the boot device prioity and got the raid detected. The raid shows up says raid 0 functional and goes to the windows loading screen it does this for like 5 sec then goes black as if it were going to the login screen then it just powers down. Any ideas?

And on my bios settings everything is stock didnt do any overclocking. I disconnected my cd-rw and my dvd rom, my ide backup drive and booted with my raid and vid card, still crashed, i then booted into safemode and i was able to go around in that. Do you think i need to reformat? Also, when i reconnect my ide backup to try and backup stuff in safe mode, it doesnt boot into safe mode. So im sure it isnt a grounding problem. Any ideas? Should i just backup to cd-r and see if a reformat works?

Well no virus's and im kinda confused, i can get into windows safe mode and stay in it as long as possible, im beginning to think there is some hardware conflict but i wouldnt even know what. Also it kinda smells like burning plastic in my case not as bad as the first time, is this just the new psu breaking in?

Computer Shuts Off Randomly, But Infrequently

I initially ran it with an antec 450w smartpower (pulled from a sonata ii). By march, the system had randomly shut down a 2 or 3 times on me. It's just a spare system and isn't being monitored constantly, so i haven't been able to see these crashes take place-i would come to the system, and it would be powered down. Hitting the power button brought it back, no questions asked. It seemed like the psu was the obvious culprit, so i swapped it for the thermaltake around this time. It had been rock solid since then, running 24/7 without a hitch. However, this afternoon, the same thing happened again. Does this sound like a defective motherboard, or do i just have bad luck with psus?

Computer Shuts Off After Couple Seconds

My parents have a compaq computer they got in 2003. They only use it for some internet stuff and email. It just shut down one day and it normally won't start up at all. I looked at it for a while today and i got it going and was on the internet for about 5 minutes and it just shut down. The power light is on but nothing works. I need to hold the power button for about 5 seconds and then the power light shuts off. Then i can try to restart it but normally it runs for a couple seconds then shuts off again. I never got a warning about temp being too high or anything. It just shut down. Any ideas what the problem could be?

Windows Xp Install Shuts Down Computer

I just bought a cheap 2500+ barton to mess with since i had the extra parts lying around. So i put everything together and it boots fine and all but whenever i try to install windows xp my whole system just turns off like u pulled the plug. Also you can't even power it back up without switching the psu off and back on. Now the weird thing is that it shuts off at the same point in the windows xp installation every time. It does so when its done loading all the misc drivers for raid, usb keyboards, etc. It says "setting up windows" and then goes kaput. Basically i never even get this far. So far i've tried different: hdd, psu, cdrom

Also the problem isn't overheating temps are fine and the fact that it shuts down at the same point rules that out. Any ideas what this might be?

Btw i have no clue whether this might affect it but i don't have a case and i'm manually starting the machine by connecting the jumpers on the board.

Computer Shuts Down Running 3d Apps

I have been having a problem recently in which my computer will tend to shut down whenever doing anything with 3d acceleration. To-day, the problem has spread, and the computer will shut down whenever i start windows. Details:- in about april, i upgraded my graphics driver (for my radeon x1950) to the latest version, 9. 3. It had just been put onto the "legacy support" list, so 9. 3 was the latest driver for a while. Ever since then, whenever i used a 3d application, the system would sometimes shut down completely (power off). The main 3d application that i used was secondlife - i found that the harder that the graphics card had to work, the more likely that it was to shut the computer down. Making the window smaller helped a great deal. When it failed, there were two basic types of behaviour: (1) it would shut down completely, and i would have to power off at the psu's rocker switch for about 20 seconds and power on again before i could run the computer; and (2) it would power down momentarily, long enough to reset the system, but not long enough to turn it off entirely (the fans/hard drives could be heard to spin down briefly). Which of the two happened was unpredictable, but seemed to be related to how hard that the gpu had to work. To-day, i went to log into secondlife while i had a number of other cpu-intensive applications running in the background (nothing using 3d acceleration, however). I stepped out of the room to do something else while it started up, and heard a very loud crack noise coming from the speakers, followed by an intense high-pitched whine sounding like audio feedback. I returned to find the screen blank, as if the system had partly restarted. I turned the computer off and on again (no resetting of the power switch was needed); however, when i booted into windows (windows xp pro), it shut down again before getting to the login screen. This behaviour continued indefinitely on every restart and was consistent. I took the side off the computer and blew out all the dust with an air duster in case it was overheating. I checked that all the fans, including the gpu fan, were working. I was able to get into windows in safe mode. I found and downloaded a revised driver (9. 3. 1), and uninstalled the old driver, hoping to re-install it on system startup. When i restarted not in safe mode but with the graphics driver uninstalled, it got to the login screen and let me in to the desktop, but then shut down about 30-60 seconds later, whilst it was still loading the various background programs. This behaviour again was repeated consistently. The sound card still worked, as sound was played when the "new device detected: vga adaptor" message was displayed. I then used a ubuntu 9. 04 live cd, which worked, although, of course, is slow. That is what i am using to write this now. General:- i know that i have had the original problem for a while, but i have been rather too busy to deal with it. It is now critically interfering with the use of my computer, and i should be extremely grateful for any assistance. Is it a problem with the graphics card, motherboard, psu, or all three?

System specifications:-

Pentium 4 2. 4 @ 3. 0ghz (northwood, have had it (and had it overclocked) since 2003; fsb overclocking only, unlinked from the pci bus which has never been overclocked). 2gb of ram (dual channel
Asus p4c800-e-deluxe motherboard
Ati radeon x1950 agp graphics card
Windows xp pro (service pack 3)

Troubleshooting A Computer That Randomly Shuts Down

I am going to be troubleshooting what is causing my cousin's computer to shutdown randomly. Just looking for good ways to troubleshoot and what would most likely be causing it. Right now my main suspect is the psu, but i am still not 100% on that. The computer only shuts down when he was playing age of empires 3. Really the only game he plays, so i can't say if that game was the only one causing.could be anywhere from 5 minutes to a couple hours before it happened. I did do a few searches to see if it was just the game. I got a few hits (4500 on google), but it could just be people only playing that game at that time. I would find it odd if it was just aoe3 causing this too. Trouble shooting that i have done so far. I ran both orthos and furmark at the same on the computer for 30 minutes trying to see any over heating or if the computer crashed. I figured this was one of the most intensive test i could put on the computer. Nothing happened either. Gpu reported a temp of 75 *c max and cpu reported 50 *c max. Going to do a gaming session to see if anything happens next. Vga drivers are up to date. After running both orthos and furmark i am convinced there is not a heat issue at the moment anyway. I did not see any of the snow effect on the furmark rendering to show if the vga was dying. If the system does stop randomly on me i'll throw in my psu from my computer to see if the problem persists. Thoughts?

Specs:
Intel e5200 @ 2. 5ghz no oc
Asus p5e x38 mb
8800 gts 512 w/ hr-03 cooler no oc
Ocz 600w psu

Vista Computer Sometimes Unexpectedly Shuts Off

My new vista computer sometimes unexpectedly shuts off. Any suggestions? There are two times when i have noticed it stopping for a reason. Other times i do not know why it shuts off. Once it stopped after i had a flash drive in the usb port. I did the proper procedure for "safely removing" it, but the computer still shut off when i took the drive out. Another time the computer more or less went to sleep. I was able to restart the computer without it rebooting. I wonder if there is some way to set the time for it to do this.
