Constant Freezing!

[cepS]

Ok, yesterday I got home from work and my pc was frozen, I rebooted, logged in and it froze again. After a few more attempts at this I finally booted into safe mode to see how that would fair out. I got in and started backing up as much as i could. Shortly after being in safe mode, I froze again.

So i said, screw it im just going to format as it felt like a software issue. I formatted the drive, and got roughly 3 mins into the XP install and it froze again. After several attempts of pure and utter fail, i decided to run memtest.

Memtest ran for an hour and a half with no freezing at all and returned zero errors. Figuring that it ran for well over an hour without a problem, i assumed that it must be my hard drive as it only seems to fail when its being written to or read from. I went out and bought a nice new hard drive, threw it in my pc and attempted to install Vista this time.

Vista installed fine, however once i logged in to my fresh OS, it froze on me. I literally havent installed drivers yet either.

So, my question is: wtf? what piece of hardware is causing this failure.

Im not suspecting my power supply as I have no problems starting/rebooting/shutting down. Also, when everything is frozen, power is still going to the mouse/keyboard and fans.

System Specs:
EVGA NFORCE 680l SLI
4 GB Ram
Now a 320 SEAGATE SATA Drive
Intel Duo Core 3.0
700 Watt PSU
NVIDIA Nforce 8800 GTX 768MB

Try checking your CPU temperatures in your BIOS after having it running for a while

CPU temps are fine, also, i cannot run it for awhile, freezes within 10-20 mins.

Something hardware is wearing out and confusing Windows and or your motherboard. Make a backup

NOW!

The most common parts to fail IMHO are your PSU and your hard drive. Freezing is more associated with the latter than the former. See advice in red above... :rolleyes:

But it could be any add-on card, pci, pci-e, etc, perhaps one recently installed or even a video card about to give up the ghost...
