Motherboard For Intel I3 Cpu

What motherboard would you suggest for an intel i3 cpu? I want to buy a new system for gaming mainly i will be pairing an i3 cpu with the gtx 460 (the 1gb/256 bit version) but am not sure on what motherboard to buy, any suggestions?

Price range is between 100$ - 150$, please note that i do not want a matx board since i want it to have more room if i decide in the future that i want to upgrade the network card or the sound card also it's ok if the board only has 1 pci-e 2. 0 slot.

Overclocking - Put Cpu To Different Motherboard

In my computer i cant overclock because my motherboard is an intel one. But my brother has the same socket as me and he can overclock cause he has a foxconn motherboard. So what i am trying to say is that can i put my cpu (socket 478 3. 0 ghz) in his motherboard and overclock it to lets say 3. 4 and put it back in mine. Will mine still be 3. 0 ghz or will it turn to 3. 4?

Hardware Compatability Memory, Motherboard, And Cpu

I've been browsing over intel's site and looking at their new 875p chipset, and it says it supports a processor with a 800/533fsb and ddr400/333 memory. My question is, can you use any combination you want as in a p4 800fsb and ddr333 (even if it's not optimal), or how about 533fsb and ddr400 memory? Whats the general rule on using mismatching meory and cpu fsb?

Psu Died, Has It Fried The Motherboard Or Cpu ?

My corsair psu recently died and it is sent off for rma. In the mean time i have connected up a spare psu. I stripped the pc down to ram, gpu and cpu. Out of the case, onto cardboard to avoid shorts. With the old dead psu, on powering up the pc, no video output, no post beeps, cpu/gpu fans did not spin up. With the working psu - cpu & gpu fans spin up for a few seconds then die, spin up again, and die, etc etc. Cant turn it off from the front (need to switch off from psu). No beeps, no monitor signal. Took out the cpu - now if i connect the cpu fan, it spins up and keeps spinning. The led on the front of the pc comes on and stays on. I can turn the pc off from the front switch. Still no post beeps though. From this - is it certain the motherboard is dead? Or is it possible the cpu is also / instead of dead? I dont have another system to test them on. So i am going to have to buy either a new mobo or a new cpu but i am trying to work out which i need.

Motherboard With Support For Quad Core Phenom Cpu

Anybody here know if amd and ati are going to have asus create a motherboard with quad pci express 2. 0 slots for crossfire x and pci slots that are actually out of the way of the pci express slots. Unlike the asus m3a32 mvp motherboard which is a horrible design for quad crossfire with hd 3870 video cards because all the pci slots for sound cards are covered up by the dual slot video cards. Please help me i am very very anxious and antsy ! I have $3, 500 for a new computer and it has been burning a hole in my pocket. I want a motherboard with support for quad core phenom cpu, crossfire x (quad crossfire) for 4 separate dual slot cards, and a pci slot that is out of the way of the video cards for a sound card. Anybody know when these motherboards are going to be released if they even are going to be made at all? If they don't go with quad crossfire because of the space issue (you need a case such as the thermaltake armor + with 10 expansion slots on the back of it) then they will most likely just release their hd 3870 x2 card and not worry about making a larger motherboard design to accommodate for 4 pci express 2. 0 slots along with separate pci slots.

Motherboard Won't Boot Up - Memory Problem

I recently built a system using pc-4000 500 mhz. Ram the board is only spec'd for 400 mhz. It won't boot up. Msi says this will cause it not to boot up. Geeksquad says it won't affect it. Do you think this is the problem, or is there something else to look for.

Dual Cpu Computer Won't Boot

I'm having problems with my dual 2ghz athlon mp computer. I've had it for over a year and all has been fine. My setup is 2x athlon mp2000, 1gig samsung ecc, tyan s2466n-4m. I have tried various video cards including radeon 8500 and voodoo 3 and it doesn't boot up. So within the last week my computer was having some odd issues, it was rebooting itself every now and then. I decided it was a power problem and pulled out some extra pci cards that i didn't really need. It seemed to quell the problem as it didn't reboot as often. Then yesterday it just started rebooting wierdly again. When i woke up this morning the computer didn't have a video display, so i rebooted it. When i reboot it, it doesn't display anything to the screen, though the hd does spin up and the fans turn on. I pulled out everything but the ram, cpu, vid card, and a few fans. It still doesn't boot up correctly. The hd led on the front of my case also doesn't light up anymore when i turn on the computer. A few things of the past, the internals of my case have been running at 40-45deg c, and the processors run at average at 55 deg c. There have been a few cases where the processors have gone up to 80deg c because a fan died, but i have caught most of those cases within a short time and the computer still worked fine. Also i dont' get any beeps or sounds when booting so i think the ram is okay

Can anybody help me diagnose the problem? I think it is either the m/b or one of the processors. I don't have access to other cpus/mbs offhand, so i want to be sure of what is broken before i go buy a replacement. Please respond asap, i'm in school and most of my work is on the computer.

Mouse Unplug Causing Problems

If a ps/2 mouse is unplugged or plugged into a machine while the machine is on, can that cause the machine itself to malfunction besides not being able to use the unplugged item? Is this for keyboards as well?

The reason i ask is because i'm having trouble with a mouse hooked up to a kvm and i want to do some testing to find out what the problem is, but i don't want to be causing problems for the machines hooked up to the kvm.

Keyboard And Mouse Freeze - Must Unplug Computer

Nearly everyday my iq504 will suddenly just freeze up. The mouse and keyboard are completely unresponsive as well as the touchscreen. Ctrl-alt-del does nothing. The only choice i have is to unplug the computer (basically crashing eveything i may have had open at the time) and then restarting it up. Sometimes this happens while i am in the middle of using internet explorer, sometimes using microsoft money, sometimes using ms-outlook, etc. I have also had instances where everything was fine, i get up to get a soda, come back and i am frozen up. I wasn't even touching the computer and only left it for a couple minutes and this happens. Is this happening to me uniquely or do others here experience this as well. If so, has anyone found a solution? I've already downloaded the latest drivers from the hp website. I don't know what else to try at this point.

Wipe Clean Pc

I have an old dell tower and i want to wipe it clean, can i do this?

Answer:- the first thing to do is too find out whether there is a partitioned os system installed. If the following doesn't work then you haven't a partition and no harm will be done. Okay so its hit the fan. Factory reset, give it a birthday, you've nothing to lose by the sound of it. It depends on a number of things whether this will work, e.g. How old is it, what manufacture. Assuming xp o. S. Within partition. You'll have no worries, this won't work if you haven't a partition, so give it a go, first switch off the offending pc completely (important). Now switch on, immediately and continuously tap f11, or hold it down (this f number can vary (e.g. F12) with manufacture) this will bring up, as the pc whines up, initially the factory reset page. Select the top option "a complete destructive reset". The complete factory reset option is what you want, don't be shy, and don't partially do the job. Press okay. Don't be nervous, answer a couple of question (e.g. English etc. Yes) it'll then say something like, "this might take a couple of hours" go for that. Now go make a coffee, come back in 30 mins and it's as originally received, just outta the box. You should install soonest a reputable antivirus program (norton) and leave the pc on-line over night to auto up-date, this is can be time consuming, and best done whilst you're asleep.

How To Clean And Fix Pc For Free?

Answer:- if we keep our pc clean, it will never get slow and work smoothly. There can be the following possibilities to make a pc slow:

1. It is possible that your pc may have so many programs running in background that use memory and may be there is not enough main memory to run your main programs. To see and remove all running background programs:

A. Press the ctrl + alt + delete keys at the same time. B. Click any program or task except explorer or systray. C. Then click end task. Repeat steps 2 and 3 to quit all programs except explorer and systray which are necessary components of microsoft windows. You should now have a clean system, however you have just removed the programs from your computer's memory, they will all return the next time you start windows. If you don't want certain background programs starting when you boot, use the start/search function to find the program and either configure it not to run at startup, remove it from programs/startup, or delete it from your system. 2. Your hard drive could be too full of data to function efficiently. There should be at least 300mb-500mbs of free space to allow for disk file chores. Note that this mostly applies to the c: drive or whatever drive your window's cache is on. If your c: drive is too full, delete unused programs on the c: drive to make space. 3. Your computer could have a fragmented hard drive. This results from programs being loaded and deleted. Run the window's hard drive defragmenter (defrag) once a month. 4. If your pc has 256 mb of memory or less, or you like to play games, you may not have enough system memory to run your software efficiently. You must upgrade memory to 512 mb or more. 5. You could have old or conflicting windows device drivers. An example would be you might actually have two entirely different video drivers on your system and windows could actually be alternately using both of them. To prevent this problem, first boot the computer in safe mode by pressing and holding the f8 key during startup, after the dos memory check has completed. While in safe mode select start/settings/control panel/system/devices. Click on all the devices and see if the various drivers have any yellow or red exclamation marks (which indicates a driver conflict) and also determine if there are any duplicate drivers that can be eliminated. You may have to delete and reload a driver to correct these problems. Duplicate drivers can and should be deleted. 6. As each new windows program is installed and uninstalled, it leaves behind parts of itself that can slow down or crash your computer. These are mostly .dlls and other shared files. It's also very possible when uninstalling a program that needed windows system files can be deleted. When your computer asks if you want to uninstall shared files it's usually safest to say no - even if your uninstall program claims the files are not being used. Old windows drivers can be found by booting into safe mode, then opening control panel/system/devices and ridding your system of old drivers. Another option is to use various system cleaning software. Otherwise, the only real answer to this problem is to reload windows into a new directory which eliminates all old junk and leftover files. This is something to do last, as you will also have to reload all your windows settings, drivers, and programs. 7. Your computer could be full of adware, spyware, viruses, or trojans. These are all nasty programs that literally take over the functioning of your computer so they can run their programs. You definitely don't want any of this junk on your computer. To get rid of these parasite programs, and to prevent them from installing in the first place, you need and up-to-date firewall, anti-virus, and anti-spyware programs. These are three separate software programs that must be running at all times except for when you are not plugged into the internet. It is very important that these programs continuously update themselves or they will become out-dated and will no longer be useful. These programs can be purchased together or from separate manufacturers.

Does Nvidia Not Clean Out Their Own Drivers On Purpose ?

I was putting in my gt 240 for physx the other day and had to uninstall the drivers. When running driver cleaner i saw that there were a lot of nvidia driver files left on the system. I have seen a lot of people on these forums since coming here that they are having problems going from nvidia to ati, but not as much the other way around. This made me put two and two together and ask does nvidia purposely leave a lot a drivers to *** with people upgrading to ati?
