As the title says, my computer has been randomly locking up since last night. I have a hunch that my graphics cards are behind this. I've been toying with mining (bitcoin) lately, and haven't run into any sort of problems. For those who are unfamiliar with mining, it utilizes the GPU's ability to perform repetitive calculations. When mining, the GPUs are both under 99-100% load, and with that being said, they tend to get quite hot. To help manage the temperature, I downloaded MSI Afterburner to underclock the GPU memory clock. My cards (system specs will be below) come with a stock memory clock of 1200 MHz, and I clocked them down to 600 MHz. It stayed stable for a few minutes, then all I got was a white screen. No HDD activity, no control+alt+delete, nothing. Just a hard reboot with the button on my case. I rebooted, thought it was weird, and went on with my day only to have the same thing happen. I've been toying with the configuration and it seems like I cannot rid myself of the problem. The screen has gone white, black, reddish-white with vertical bars.
I have uninstalled MSI Afterburner since I reset the memory clocks. I have uninstalled/reinstalled the AMD Catalyst Control Center (drivers and the whole nine yards). I still get the problem.
Here is where I think it gets weird. I have two graphics cards, and have tested each card on its own. Both seem perfectly fine (system is stable, no lockups). I have tried running both cards together using different PCI-E slots than in the original set up, and they're fine. When I revert back to the original setup, I experience more lock ups. I also have tried using alternate CFX cables with no avail.
Now, I have taken a peek into the event viewer, but I'm not exactly sure what I would be looking for, and it seems like whatever I find is irrelevant to this issue. I have the cards running fine right now in an alternate configuration, but this configuration doesn't allow me to have my audio card plugged in, so I will not keep this configuration.
Please let me know if I can provide any additional information.
System specs:
ASUS M3A32-MVP Deluxe WiFi/AP edition
AMD Phenom x4 9950 BE 2.6GHz
4GB Mushkin Ram (I can look up the exact specs if required)
Antec High Current Gamer 620W Continuous (Newer than other parts, never had a problem with it)
2x HIS Radeon HD 6770 850MHz Core 1200Mhz Memory
HT Omega Striker 7.1
