I recently opened up my case to clean some of the fans out, including my 3d card fan. Upon replacing everything, all of it turned on, but no signal was received from the 3d card to the monitor, so I reseated it to make sure it was in correctly. On the next boot, the 3d card would not even power up (fan would not move and light on it would not light up) and the 2 fans on the side of my case would not work either, yet all other fans and everything else seems to run fine. I tried swapping plugs thinking maybe since only a couple of the fans were not working it might be a problem with the molex connecter, but whichever one I plugged in it would still not receive power. So then I decided it must be a PSU problem, I swapped my current 500w psu with a brand new 450 psu, but still same results. Could this be my mboard or ram or anything? Sort of strange that it powered up at first but no signal was sent, and then the card would not power up at all. Oh yeh, btw, 3d card is a Leadtek Winfast PX6800GT 256mb. Just looking for some suggestions or thoughts. Sorry if I missed anything. ( Not certain which service pack of XP Pro I have, sry)

Oh, forgot one thing, I also swapped the Leadtek 6800gt with a Geforce5800fx 256(something along those lines) thinking of course, must be the card, but still no signal from that card either.

are you connecting them to the power supply?

Hellz Yea!

The 6800gt connects to the power supply, but the other one just to the board. Im thinkin its the board??
