Video Problem (Friends issue)

[Vanquished]

Hey everyone, my friend has been having this issue with his computer:

"my computer starts up but has no video output. from the sound of the hard drives, the system seems to be intact except that there is absolutely no video output. i have a nvidia 8800 gts. this problem is brand new after replacing the power supply and i'm positive that everything is connected correctly. i've gone through a few psus on the system, the previous one being mistakenly underpowered and blowing after a few minutes, yet the video still worked then. this new psu should be fine. could something have happened that would have damaged the video card? or is this something that is wrong with my mobo/bios setup?"

Any help would be greatly appreciated.

Thanks a lot,
Jack

unplug the cable and put in on the other connector, as strange as that sounds i had a similur issue and it would not put out any video until i move the connector over.

Strange i thought so i shut-down pc and move it back, again no video.

Could always remove card, make sure slot is clean, then reseat the card

A common thing I've seen is that people forget to plug the power supply directly into the video card. Newer video cards commonly have a place to plug the power supply directly into them and they won't work without this.

Thanks for the replies. All the cables were correctly plugged in, and I lent my friend my video card and still nothing, we've decided it is a failed Mobo. Oh well.

Thanks again,
