Weird problem with XFX 5870, what to do?

[Korialstrasza]

I just upgraded to an XFX 5870 from a Geforce GTX 260. My system was rock solid and stable with the GTX260. With the 5870, every time I turn on the computer, the fans on the card run at 100% and I get one long beep followed by 3 short ones. Then, I switch off the power supply and jiggle the card very slightly and then switch the power on and it works fine.

I'm going to go there and figure out what the deal is, but is there anything specific I should look for? When I first installed it, I always make sure the card is firmly seated and both screws are installed securing the card to the case. Yet a slight jiggle works. My 260gtx worked fine, so it must be the card?

Could there be dust in the motherboard's socket or something I should look for?


Thanks guys!
