I have a dell inspiron 531, I have installed a 750 watt psu and a nvidia geforce 9800 GTX+ Superclocked edition and 4 gb of ram. I have used this rig for over a year now and the other day i took it aprat to clean the dust out and when i put it back together its ignoring my graphics card. It will only use the onboard video. My card does not show up in device manager and i have set in the BIOS to use the PCI-E slot before the onboard. I have tried reseating the card and the ram and unpluging all uneccesary things but i am having no such luck. I have also tried removing the battery to reset the CMOS and that still doesnt work. I am beffudled as to what happened all i did was take the card out and blow away the dust and then put it back in. i checked the contacts and the pci-e port for dust and debris but there is none. PLEASE HELP ME!!!

i used one of those braclet things that clips onto the case to ground myself.

i tried the card out in a different computer and it works, after fiddling with it in mine i got my computer to boot using the graphics card once but when i turned it off to add the extra things (gamepad, headset, etc.) and then turned it back on it stopped working.
