i had bought a new shiny evga 8800gt and it didnt work out of the box. i did some bios updates and after numerous tries it booted and worked fine for months. then out of nowhere my comp wouldnt boot. i tried everything...taking out ram,taking out soundcard, etc. i replaced the 8800gt with my spare 7600gs and whammo comp starts right up. i rma'd with evga and the replacement had the same problem. i used it as an excuse to get a corsair hx520 to see if maybe i had just burnt out the thermaltake psu. no duck sauce. anyone have any idea whats going on? did i just get a bad string of cards. is it possible for the pci-e slot to be broken but still manage to work with the 7600...seems unlikely to me. any insight would be great. i havent played games for a couple weeks now and i'm starting to go through withdrawal.
