Ok, in August I built a PC with Windows 7 64-bit Ultimate. It has an Asus M4097XTD (I think) mobo, AMD Phenom II x4 3.4 ghz processor, ATI radeon hd 5830 gfx card, WD 600gb 7200 rpm hard drive, some typical cd/dvd drive, an antec 1200 case with enough fans in it that it actually cools you off when you sit by it, and a Cooler Master 1000 watt PSU, and 2 2GB ddr3 Mushkin RAm at 1330 mhz (I think)
The stupid thing just resbots itself at total random. It may work fine for a few hours, maybe even a day or two, then bam it rebots itself. Once this happens, it will start happening progressively more frequently until the thing is not useable at all for more than a minute or two. There is no rhyme or reason to what the computer is doing when this happens. Sometimes you can play STALKER call of pripyat at about max settings with the card and or processor overclocked and it will run super for six hours. Then other times it will reboot while surfing the net or just idle on the desktop doing nothing at all. It seems to work better during the day than at night, and after a series of reboots it seems to perform better if I just leave it off and go to sleep, then when I wake up it will work again for a few hours.
I have reinstalled Windows three times (and made sure to update from the beta version of the OS I was using to a more legit version). Each time before doing this I used a KillDisk utility from Hiren's Bootkit to write zeroes to the hard drive.
It's never had spyware or viruses when I scan for them
Windows firewall is turned on.
I have taken it to a computer repair store 3 times and they never seem to reproduce the problem, they were able to run furmark and prime 95 for one whole continuos day with no interruptions and I have the logfiles to prove it.
I have tried this computer at three different people's houses and the rebooting still occurs.
I have switched out the gfx card to try an nvidia 8800 GT and that doesn't matter either.
I have already replaced the RAM once and had the voltage settings set to the correct parameters, the last memtest I ran for 9 cycles was fine.
I have tried using an uninterruptible power suply with no change in the problem
Overheating just seems impossible, I have never seen any part in the machine get hotter than 54 degrees celsius during any of my activities. The case has three 120mm fans in the front, two more in the back, and a masive 200mm fan on top blowing right down on the gfx card. Like I said, it actually is cooler than room temperature if you stick your hand inide it while its running.
I thought I had fixed it when I replaced the original 750 watt Cooler Master PSU when I discovered that a small screw had fallen into it, which I thought was causing the PC to randomly short circuit some how. Now I use the 1000 watt PSU as described above. It worked flawlessly for a day and a half before resuming its reboot problem.
Sometimes it works ok when I boot in Safe mode with networking, other times it doesn't. Same goes when I boot through the Linux based ASUS express gate thing that came with the mobo.
It used to go to a blue screen when this would happen, the code usually being 7E, 1A, or 3B. Now it either no longer has a BSOD error, or just flies right by the screen so fast you can't see it, I'm not sure.
None of the bugcheck codes in the event viewer signify anything of importance, and any explanation of the BSOD codes seems to be "well we can narrow it down to hardware, software, the power in your house, and what you wore to work on the twenty-third thursday of the year 2005".
I see two options. Find a priest to perform an exorcism on my PC, or break it up into parts and sell it (assuming none of you can help me.)
Please help, my whole semester has been frustrating and sanity eroding as a result. I have spent probably well over 100 hours messing with it that should have been used to study, and what do you know my grades are underachieving as a result.
