I've got a rather annoying problem with my computer that I built and just upgraded.
Here are my system specs:
OS: Windows 7 Ult x64
Mainboard: Asus M4A89GTD PRO/USB3
CPU: Socket AM3 Phenom II X4 965 (3.2 ghz)
RAM: Corsair 4x2GB DDR3-2000 (Clocked on BIOS to 1748 - can't seem to go higher)
HD: Seagate 1TB 7200RPM (2 250GB boot partitions and 1 450GB storage partition - one boot partition used - <2 years old)
DVD-RW: Asus DVD-RW
Graphics: 2x XFX Radeon HD 6950 in Crossfire
Power Supply: XFX 850W Power supply (advertised as SLI/Crossfire ready)
Case: Lots of fans and good airflow
Monitors: 1x 17" VGA (DVI-VGA adapter) and 1x 22" DVI Widescreen (Primary)
One of 3 cases:
1. Computer will boot but say it cannot detect HD
2. Computer will not reach POST (Ie no beep code) and simply run with all fans on high.
3. Computer will boot and run for at least a day and then crash with a screen freeze.
What I have tried:
1. Pulling both cards out and booting on onboard graphics only. Boots just fine every time.
2. Pulling one GPU out and running it on only one GPU. Sometimes boots normal and sometimes wont go to POST (no beep code just fans running on high.)
3. Both GPU in. Will still boot and run for over 24 hours but crashes with screen freeze.
4. Testing all the voltages out of the Power Supply. All seems fine.
5. Putting the HD on different SATA ports.
History of errors:
This setup was working flawlessly for 2 months with no crashing. One night I'm about to hit the sack, I have Diskeeper, Diskcleanup and Malwarebytes going. Half an hour later the computer reboots. I'm lying in bed about to sleep and decide it can wait until morning. When I wake up I see that it has rebooted and cannot detect a boot device. I'm on winter break from college and decide to see if I can find out whats going on.
I go through a lot of different combinations and pull out both GPU's and it boots normally . All through this point is has gone past POST and has shown an error saying no boot device.
From this point on the error changes. Now instead of saying it can't find a boot device, it won't even give a beep code, just runs with fans on high. Put in one GPU and it boots, although with the other GPU it didn't boot initially. Later it booted fine. I ran it for over 24 hours and it crashes again. This time while I'm having one of my most successful games of Europa Universalis 3. I toyed with it a but more but I simply can't get it to even give me a beep code, it just runs the fans on high.
The fact that it has had these same symptoms before and I was able to run it for over 24 hours (including a reboot) without an issue tells me I've got a hardware problem that seems to be fairly hidden.
Now the fact that this problem started 30 minutes into a Malwarebytes scan worries me. I am forced to wonder whether something damaged my mainboard or something got written into my BIOS when I wasn't looking. Those are extreme cases. No I don't go questionable sites and the only virus I've gotten in the last 2 years has been that damned SecuRom worm thats buried in Imageshack and Megaupload (mostly Imageshack though). I've gotten very good at removing it (god bless Regdelnull).
So I'm seeing either 1 issue or 2 issues going on at the same time.
So my personal list of things it could be are as follows:
2. Power Supply
3. Graphics Cards
4. And maybe the Hard Drive
My stress level: Very high
Thats about it.
Can anybody help me?
