Think I might know what it is... it happened after I hooked up this fan in there. It was a blower I had in there before my i bought my second video card. I threw it in the floppy bay to shoot some air in from the front of the case. Works nice and keeps things cool, but I am thinking maybe that is causing power fluctuations in my video cards, causing inconsistencies.
Anyone think this may be the case. I can't test this until i get home cuz im at work
