I have a desktop computer issue that has been baffling me for a couple weeks now. The symptom of the this issue is that when I do random functions within Windows and I am getting a full lock-up (basic color palettes in pattern across entire screen) with the only option being a hard restart after powering down the computer manually.
These are the system specs. Nothing is overclocked, factory settings.
DX58SO Intel motherboard
1600 Mhz 9-9-9-24 Corsair RAM in 2 GB sticks (various amounts 4gb to 8gb)
Corsair GS700 700 watt PSU
BFG NVidia 280 GTX
WD 500 GB HDD
It sounds like "artificating" of the video card, but I can assure you this happens inside of Windows at times, when I launch say Outlook and firefox and put a load on the system. It will be locked up if I leave the computer idling sometimes and I can back to the rainbow lock-up screen. The video card is manually overridden to run at 100% fan speed at all times.
The case looks pretty clean, and this wasn't an issue until about 2-3 weeks ago. I replaced the PSU with a bigger one, still having the same issue. I've pulled all but 4gb of RAM and it still happens. It seems that I can catalyze the problem by running more intense applications (i.e. MW3 or battlefield 3 w/ pandora, firefox, outlook, etc running) so could it be in the CPU?
I did use Intel Extreme Tuning Software once to "very slightly exceed factory specs" and it ever-so-slightly adjusted the ram, cpu by literally like a 1% OC. I reverted.
I am pretty handy with computers, but I need advice on this one. This usually made me think video card but I just don't see how it is. I have a 9800GT as a backup I could use to test this theory, but I figured I would take it to the forums first.
Thanks in advance
