Random Power Failure


Lately, my pc has been randomly shutting off. I thought it might be a software issue, so i went to reformat my hd when it powered off. Here i am with a box w/ no os that keeps shutting off every 5 minutes. Every other computer in my house works fine, so it isn't an electricity issue. I also replaced the power supply, which cost me $60. What else could possible be causing theis odd phenomenon, because i would like my pc back.

Antec Power Supply Failure

I've built quite a few desktop pcs systems, from motherboards, etc. And, i've also repaired quite a few machines (e.g.compaq, hp, gateway, etc). It seems that power-supplies are the failure point much more often than i had expected. Once again, a couple of days ago, on a six-month old machine i own and built, (with good fans, no overclocking, etc), i inserted a 2nd ethernet-pci card into it, and when i brought it up for the first time, it wouldn't boot. (No smoke or noises. )The little activity light seemed to indicate random action, just as though it was seeking the disk and booting, but nothing ever showed up at the console, not even initial bios output. So, i took the case-side off, and hooked up my little power-supply tester-unit. Sure enough, one of the tester's multiple green lights did not light up, and that red 'danger' light on the tester did light up! [It's a fairly nice antec 400-watt supply, which is plenty of wattage for this system. It is an antec model sp-400 'smartpower'. ]

Any advice or comments about how often power-supplies fail, or thoughts about why this one might have?

Power Supply Failure Rate

According to be hardware these are the power supply failure statistics for the previous year, like all statistics they should be taken with a pinch of salt. They confirm though what most hexites knew already. Fortron: 0. 7%
Hiper: 1. 2%
Seasonic: 1. 4%
Thermaltake: 1. 6%
Tagan: 2. 8%
Enermax: 3. 0%

Display Memory Read / Write Failure - Pc Gives 8 Beeps After Power On

I just installed an athlon 64 system. I kept getting 8 beeps right after i turned the power on and once in a while. According to by motherboard manual it means "display memory read/write failure" i never had this problem before with my old athlon xp system. What's wrong here?

Computer specifications:

Gigabyte ga k8ns ultra-939
Athlon 64 3200+
512 mb ram(had to take out 2 slices because the mb doesn't support 3 slices of ram)
Evga geforce 6800 gt

Random Reboot / Power Off During After Post

During boot, post, entering/configuring bios setup, and also windows xp pro startup, computer will shut down as if power was disconnected, sometimes not attempting reboot, sometimes it tries to reboot. When it tries to reboot, the system and fans kick on for a second, and shutdown, then try again a few times. Sometimes when it wont try again, i have to turn psu switch off, then back on, before it will attempt another boot. Here is how it went down:

I assembled the following parts on kitchen table, no carpet, using esd wrist strap:

-Asus p5b-e motherboard
-Intel core 2 duo e6400 2. 13g 775 2m
-Antec sp-500 power supply

-1gx2|patriot 240p memory
-320 gig western digital hdd, 7k, 16m sata2
-Samsung ide optical drive
-Nvidia vga xfx pvt71pudp3 7900gs 256 mb

-
Detailed history

1. Assembled parts using esd wrist strap. 2. Upgraded bios from p5b-e601 to pfb-e706 via usb flash drive. 3. Installed ms windows xp pro, mobo drivers, other drivers, nero, and lastly mcafee antivirus, the mcafee forced a reboot without confirmation. 4. During post, "error: overclocking failed"

5. I reboot, and set bios to defaults. 6.computer will not boot all the way now, usually rebooting during post, often failing after only a few seconds, then trying again. 7. To get computer to attempt boot, i have to turn power switch on back of psu off, wait till mobo light goes off, then turn on. Mobo light turns on again, i press chasis power on, and same thing, it boots for about 2-30 seconds, then powers off without warning. I hear 2 beeps followed later on by 2 more beeps, same length. 8. After waiting 30 minutes with psu switch turned off, i turn it back on and attempt another boot. It gets only slightly further, then says again, "warning: overclocking failed. , Press f1 fo setup, f2 to continue. 9. I press f2 for the fun of it, it starts loading windows, then powers off again. -

Is this a bad power supply? I suspect its a hardware issue, but i need to find out which piece of hardware to send back before my return policy expires.

Computer Random Power Cut - Voltage Problem

I left my sony vaio pcw-? On one night and when i woke up it was powered down. I pressed the power button and nothing happened. I unplugged the cable from the wall, plugged it in again and the computer beeped. The power came back on and i was able to start the computer. However, i got to the bios screen and was met with a message "hardware monitor found an error, please hit f2 for details". I hit f2, went to power monitor (as the computer told me) and could find no obvious error. The mobo and cpu temps were 40-50 degrees. I did notice that the power fan stats were a greyed out n/a but sometimes it would spring to live for small bursts. The other two fans were fine. The power voltages looked strange. The +12 voltage was actually +11. 3-7. It keeps fluctuating. Anyway, the power keeps cutting out. Sometimes the computer will boot up and last for 30 mins, sometimes 3 hours, but it always loses power at some point. The computer is one of them "all in ones", with the box stuck to the back of the monitor. I opened the case for the first time yesterday, unmounted the hard-drive to have a look for unconnected wires or the like, but its very complicated in there. I am running a basic celeron 2. 2 processor, 256mb ram, sis 651, mobo is called komugi (guess in english speaking countries it woud be pizza or summat?) No upgrades or overclocking.

Intermittent Boot Failure

The problem is intermittently the system powers up but fails to even attempt to boot - no bios beeps, and bios and vid. Bios screens not displayed. Drives spin up ok. Have tried different case and psu (in fact system is currently in borrowed case). The system only ever fails to boot if the system is cold-started - the system warm-reboots ok. Tried different ram, had m/b replaced once, new m/b been returned to dealer where they (supposedly) found no problems when tested with other kit and with my psu, but system not been professionaly tested as a whole. Have also tried different graphics card, removing modem and sound card, running system from hdd only, but still having problems. All connectors are firmly seated. There are no config options in bios or jumpers for ram and the cpu is set up correctly and automatically. Have used 375 and 300w psus with system (300w seemed better then system started playing up again)
Nvidia geforce4 mx440 agp8x graphics card (8x is supported by m/b), and have also tried geforce2 4x. The os may be irrelevant, but i've tried winxppro, win2000, winnt4, mandrake linux 9 and a linux distro that boots from cd (knoppix). All drivers installed ok. Won't even bother with win9x/me because i hate it.

System Failure ( Restart )

Built this and it has never run without having a system failure resulting in a restart. I tested the old power supply, and the 5v connector failed. So, i bought a new one and figured that this would be the fix to the issue. And no. Any suggestions on what i might look for next? I'm lost.

Bios Flash Failure

This acer aspire m5100 desktop was having freezing issues, so i decided to update the bios to see if that would fix things. The flash was going well, until the very end where the status bar showed red, indicating failure to write at those sections. The computer rebooted and failed to post. Fans spin and everything, but nothing shows up on the monitor and no beeping from the motherboard. What do you guys think? Game over? Or is there some way to revive the computer?

Bsod - Hdd Failure

I'm running xp pro sp3. I can't remember the last time i've installed new hardware or software. Out of the blue the other day, i noticed foobar2k wasn't reading some of my music off my drive. I checked the files themselves on the 500 gb, and when clicking on the folder received a message to the effect that the files were not accessible. Found that kind of alarming. Then later in the day, experienced my first crash. Just a complete as-is freeze up with stuttering audio that never budged even after about a 30 minute wait-out. Rebooted and chkdsk popped up for the 500 gb drive. I figured as much. However, chkdsk would repeatedly fail to complete. I used another utility, spinrite, directly off a boot disc. Without even being in windows, it still froze about ten minutes into it. At this point i basically could not keep my computer up and running without it soon crashing. I pulled the 500 gb drive to just give up for now. Everything seems like it is running more or less stable with just the raptor. But then, i decided to usb transfer some of my music to the raptor from my blackberry (setup to act as a flash drive). Within about 30 seconds i got my first ever bsod on this machine. 0x0000008e (0xc000001d, 0xbf852646, 0xac387698, 0x00000000)

Win32k.sys - address bf852646 base at bf800000 datestamp 48025f2a

Anyone have any idea what could be going on? Google results for the stop code gave vague suggestions at best. I really don't even know where to begin!

Motherboard Failure Rate

I'm a system builder, and i order most of my parts from newegg. In my i7 systems i have been using the asus p6t deluxe v2 for almost all my builds, but lately i've had over 50% failure rate with the boards. This is over the last month and over 27 units. I'm just wondering if other builders are getting the same failure rate, or if i just got a really bad batch. Its so bad at this point i'm ready to switch to another board, but i'm not sure which one to move to. I need boards that overclock well (4. 0 ghz on the 920 with liquid cooling) and have dual lans. Of course, they have to support at least 2 video cards in full x16 mode also. I'm thinking of trying the asrock supercomputer x58. Any comments or suggestions from people who are having similar problems or have a great mb they've used for a lot of builds will help.

Lcd Monitors Failure Causes

To date, i have got my hands in over 10 malfunction lcd monitors. The cause of deaths for all of them but one were power failure of some sort. I think the lcd company intentionally did this to make people buy new ones. Here are some of the causes:-
1. Premature aging or leaking of electrolytic capacitor: either because of the use of capacitors with lower temperature rating or, for save a buck or two, use capacitors of un-trustful brand(s). Replace the capacitors usually brings the lcd back to life. 2. Dead external power adapter: especially the ones with a strange output voltage which is not easily replaceable. Depends on how the adapter is assembled, you might need to force it open to find the real cause. 3. The most strange ones are the so called "cold soldering": in some larger lcds, i found the solder of several components on the internal power board were loosed! Ideally the power board in a lcd monitor should not have cold soldering, which i think it is a truth when it was built. However, solder may became loose if, after the soldering work of a power board were done, there are external forces applied onto certain components (e.g. The ones connect to a big heat sink which were than stressed by screw onto something else ). In such case, adjust the angle/position of the monitor may put excessive force on the soldering point and eventually break the connection between the legs of the ics and the solder. Re-attach the solder could be your best choice. 4. Unstable relay. Due to the fact that some solid state relays are highly temperature sensitive, the current a relay can output/conduct may decreases dramatically as the temperature increases. The result is intolerable blinking monitor. For emergency, try to ventilate the relay, in the long run replace it with one of the same specification is your best choice. Not recommended, but, if you know what circuit were controlled by that relay and the function of the circuit, you may be able to short circuit it and make it permanently on or remove it to make it permanently off or connect a manual switch to turn it on/off by hand. 5. I never encounter this but lcds with faulty thermal fuse(s) or blown fuse(s) were reported in this forum. Replace the fuse might be a reasonable thing to do. However, if it blown again, you might need to check other places.

Pata Hdd Complete Failure

First my new system dies, and then my old system decides to go and kill itself aswell. Ok, this time its an old pata hdd that something went wrong with (i did this to it). What happend? Well, i had a nasty virus and had to get a real "tool" for the job. A program that use dod* method to erase everything from the harddrive. Let's just say something went wrong on the way, and now it's competely unreadable. So i got my hands on some seagate tools, and i really don't have a clue what to do with it. There is something so wrong it can't update the mbr of the drive. Shall i call it even and throw it away, or is there anything i can do?

System Failure, Monitor Does Not Show Anything

I returned from vacation. Turned computer on, fans came on, green light came on, i could hear the hard drive spin up and sound normal, but that's it. No beep, no yellow light, the monitor doesn't think anything is running, the keyboard is dead, num lock won't illuminate, optical mouse is out. Can anyone give me an idea? I'm not very computer literate ( as i'm sure you're aware after reading the earlier part of my post) the computer is a 3 year old hp.

Failure To Boot From Hard Drive

I have two hard drives. I tried installing windows vista business on the first one to use in a dual-boot configuration with windows xp which was on the second hard drive. Well, the vista installation worked fine, but when i went to boot into xp, i found vista's boot loader hadn't recognized windows xp. Clearly frustrated, i tried several different things until i finally decided to format the first hard drive. It was horrible i lost my entire data from the hard drive. Vista made my data vanish. I hate it. I tried using repair tool and many recovery software, but it did not work.

Hard Drive Failure When Booting

I have been having trouble with my desktop when i boot up. I am getting a "hard drive failure" when i boot and it asks for me to insert a system disk (which i can't find at the moment). So far i have been lucky enough that after a few tries it will finally boot up and run just fine. I try not to shut it down but from time to time i forget and shut it down only to be reminded why i shouldn't do that the next time i try to boot it up. But, i am afraid that it will someday no longer do this. I have purchased an external hard drive so i can copy the contents of the bad drive to it before i replace the drive, but am not sure what to do or how to do it. I would apprieciate any help you can give me. I have seen in another post on this site a program mentioned by the name of hdclone. I have found a free version of this and am interested in knowing if this is something i need to transfer the contents of the old drive to the external one? Also, the old drive is an ide but when i look online for a new drive they are sata or pata drives. What are they and will they work with my current setup?

If i recall correctly, the external hdd is about 120gb and the old hdd is 60gb. I am running windows xp pro. Since i am unable to locate my xp program disk at the moment i want to do everything possible to not lose this on the hard drive. If you need any further information, i will do my best to supply it.

Hard Drive With Potential Failure

I have 2 of the seagate 1. 5 tb models which i bought before i was informed of the failure rate and i figured that it would be wise to ask here if i should be alarmed because if i dont check now i never will. Basically my problem is that the drive tends to "stall" after a period of idle time. It is usually only an issue in windows but it happens too often now. For instance, i go to my computer in the morning and click on the folder on the drive (which is the secondary non os drive for storage) and it will stall and about 3 seconds later there is a small click sound as is if it were trying to find its place. It is very annoying so i really want to resolve it. The thing is other seagate drives that i have had have done the same thing to me without failure for years, and instead just leaves me annoyed. I for one am pretty mad about the epidemic with these drives but if anyone has suggestions i am open to them.

Usb Flash Drive Failure

Three times-once each with three different flash drives, and on six different pcs-i've had the experience of finding that the computer won't recognize the drive, and the data on the drive has become inaccessible. I see this is a common problem. Other users ask for advice on the web, and nobody seems able to offer any solid information on this occurrence. In none of my incidents has the flash drive been dropped, heated, frozen, or dropped into a liquid or run through a strong magnetic field. One day they work; next day they don't. Anybody know why or what could be causing this issue? And whether my data is permanently lost in such cases? Three times, three different flash drives can't be a coincidence!

Delayed Write Failure Error

Recently, i purchased a western digital premium es 500gb external hard drive. I formatted the hd from fat32 to ntfs, and reinstalled all the original software that shipped with the device. Transfering files from my pc to the my book works fine. However, when i attempt to transfer large files (usually above 2gb) from the my book to my pc, i receive a "delayed write failure" error message. The device stops responding, and i have to power it down and restart it. I am running windows xp sp2, and vista ultimate. I have experienced this problem in both operating systems. The device is connected to a usb 2. 0 pci controller card i purchased two years ago. All the ports have worked fine in the past, and i have never had problems with other peripherals connected to the port. All connections appear to be secure.microsoft kb article 908673 discusses this issue and is releasing a hotfix (kb908673) w/xp sp3. I found and installed the hotfix, and continue to have the same problem. Has anyone experienced similar problems with an external hard drive? Does anyone know of a solution for this issue?

Floppy Drive Disk Boot Failure

Just built my own computer, and i cant install an os because the computer doesnt seem to find the floppy drive. I have connected the floppy drive to the motherboard with a 34-pin connecter, and i have the twisted end plugged to the floppy drive, and the long end to the mb. I noticed that one pin on the floppy drive (the second from the side) is missing.could that be the problem or should it be like that?

When i start the computer it says after counting the memory and all that, "verifying dmi pool data. Disk boot failure, insert system disk and press enter".

Error 0200: Failure Fixed Disk 0

It is hard for me to throw away things that have been working. I am the owner of two dell inspiron notebooks. One is an 1100 (2003) and the one that is currently giving me the problem is a 2500 (2002). So you can see who you are dealing with. I upgraded the memory on both machines to 1g and 512mb respectively, not that long ago and they were working fine. Then i got this brainstorm to try to teach myself ubuntu and wiped out xp on the 2500 and burned an iso image of a ubuntu version and it was working ok except i couldn't connect to the internet even via ethernet cable. Time passed and then by the time i came back to it - there was a problem that i really can't recall - i posted on some other sites and the bottom line was, i thought i needed a new hard drive. So i purchased a compatible drive (i did a fair amount of research) and got the drive about 2 months ago and just tried to get it going this morning. I replaced my hitachi 20 gb drive with a seagate momemtus 5400. 3 40gb drive. When i boot up, the initial screen does show that it recognizes my new drive (model st940815a).

How To Prepare For Hard Drive Failure On Laptop ?

I am about to order a new laptop, i have an option between 2 120gb (7200rpm) hard drives, or 1 250gb (5400rpm) hard drive. Right now i'm planning to go for the single hard drive. One thing that i am concerned about before hitting the final buy button, is hard drive failure. I've replaced my desktop hard drives (2 of them) on a few occasions (i go ahead and change em when i think their making noise). I usually just plug in the hard drive i want to swap out, and the new one i buy, then run a program that boots off a cd to clone the hard drive. With a laptop, i don't know how simple this might be. I'm thinking if i buy just a single hard drive, there won't be a 2nd sata cable for me to clone the hard drive with. And even if there is a 2nd cable, i don't know if i can run my laptop while the hard drives are out etc. (Assuming i purchase the single hard drive, perhaps there isn't physical room to put in a temporary 2nd hard drive)

I'm not really wanting to purchase the dual hard drive option for the laptop because its just extra money wasted, and higher battery consumption as i see it. Being mostly a desktop user and only a very rare occasions opening up the bottom panels of a laptop, i'm not sure what to expect. I just dont want to get stuck in a situation where i have to buy a replacement hard drive and lose everything and do a base install etc.

Hard Drive Failure - Unknown Error

When vista loads, it gives me a message telling me one of my hard drives need to be checked for consistency. If i let it run, it either freezes, or aborts with some kind of unknown error at some point (happens at different points in the process, randomly). When i finish booting into vista, the hard drive is there, but it needs to be formatted before it can be used. If i keep letting chkdsk run is there a chance it may be able to repair whatever the issue is? It seems to get progressively further, but how far away from completing chkdsk it is, i have no idea. Edit: actually, i'm going download wd lifeguard tools, and see if i can scan the drive first, and see what it tell me. Will update when done.

Hitachi 1tb Drive Imminent Failure

I have a 'downloads' folder, and 'recorded tv' on that disk. It appears some of the downloads are gone, but the recorded tv folder still seems in tact. The drive is still working, but these are the kind of chances i don't take. I think the drive is less then 1yr old, so hopefully i can send it in for rma to hitachi. Ugh, this sucks.
