did you make sure that
1). the card is properly seated in the pci-express slot?
2). the 6-pin power connector is attached to the card all the way?
other than that i dont know it may be a faulty card
sorry to hijack this corupthalo 😉
but how was the PSU installation? What brand Power supply did you use? Did you use any special Dell connectors? I'm having a heck of a time getting anything definitive on this subject.
Thanks in advance!
It may not be getting enough power from the PSU. The symptoms you describe are concurrent with those that occured the couple times I've tried to boot my system after forgetting to plug the power cord back into the videocard.
I used a Hiper Type-R Series 580W. It came out of my old p4 which I didnt need so much power for anymore. Was a bit scary swopping it out but thought that was what was causing my geforce failures. I didnt need any special connectors but I checked the colour code of the cables from the new power supply to the dell one to make sure..
Hope this helps.
