I am having a strange problem that I just figured out the cause of, but not the solution to. I have an XFX 7600GT video card. I had it overclocked to 630Mghz/1.65Ghz from 590Mghz/1.60Ghz. I ran all kinds of tests for a few days and it was stable. I took the card and mb out to do some rearranging and put everything back together. I decided to take the computer to my HDTV and hook it up. It looked like I was having weird display problems and the system was slow, so I brought it back upstairs and hooked it up to my 22" LCD.
The problems continued here. The windows login screen looks fine, but when I login, the screen flashes blue, looks like a corrupt jpeg(if you have ever seen one of those), and is filled with tiny dots all over the place (at first, I though these were dead pixels, but they are not). The system is also slow. I booted into safe mode and VGA mode and everything is fine. I then reinstalled the drivers 93.71 and the system came back fine. I noticed that the coolbits tweak was gone, so I reinstalled it and the problem reappeared almost immediately. So, I reinstalled the drivers, and grabbed NTune and tried to make a change and as soon as I did, the problem came back.
What is going on here? Is my card bad, or are these programs just flakey? The weird thing is that everything was fine for a few days until I pulled the card out. It is seated in properly and my system functions as normal without coolbits or nTune. Does anyone else have any experience with this? Can someone please help?
UPDATE:
Ok, I thought this was just a driver issue with Ntune or something, but now I get the problem with no Ntune or Coolbits. I even tried undoing my OC on my memory and RAM, which passed 16 hours of MemTest and 6 hours of Orthos. When I run 3dMark, the screen always flashes blue between each test and then at the end, it hoses up and I get my artifacts and the system is unusable. Is it possible that the card is damaged? Could this be a motherboard problem?
