Hello, I've just recently purchased an nvidia geforce gtx 260 oc maxcore 55, trying to upgrade from a geforce gt 240.. When I installed my gtx260 into my system and booted into windows, the card was not detected, and I had to plug a separate monitor into my on board plug, because I wasn't getting any signal through through from my new card. I had also purchased a 780w psu to ensure I had enough power for it. I also tried to disable to on board graphics and installed the drivers for the new card before I installed it into my system, so when nothing worked for me I traded the card in for another gtx260, but had all of the same problems...
I'm about to try booting in safe mode and disabling the on board graphics again and reinstall all the drivers and try again...
Also forgot to mention that the card powers up, the fans are running, but it's just not being detected. I did clean the pci-e slot with some cleaning alchohol and a cotton swab, which didn't help at all, I thought maybe I did a no no by trying to clean it like that and so I put my gt 240 back in, but it worked just fine.
any help on this would be greatly appreciated.
