Hello, I have a bit of an odd situation with my case of the video not working. So I built my computer about 3 years ago now after getting an HP one and just rebuilding it with a new mboard/cpu/psu/mem/etc. and just over a few years here I have had a video card issue this new problem cost me 80 bucks for a new card that apparentally doesn't work now also, but here goes.

First card I got for my new system (I will post the whole set at the end) was a nVidia 7600gt and it worked all fine and dandy until around 6 months in my computer would randomally restart and after a few days into that the computer just plain old wouldn't turn on. First thought obviously for me was replace the card, boom done.

New card was also a 7600gt same model XFX and such, only a few days ago it worked perfectly fine then one day I woke up (usually leave comp on all day) turned on the monitor ORANGE glow. Well then... went ahead and figured oh it's just another bad vid card and checking newegg the model I bought was DISCONTUED, aint that a b.... Decided let's just get over it and buy a 8600gts to upgrade myself and get better results allright.

Well installed the card turned on the system it boots up, no signal, try the onboard well works fine, disabled the onboard tried again nope same issue. Tried cleaning out the comp dusting, replacing pieces one at a time, no change so far.

Heres the kicker, socket 939 boards are hard to come by so replacing that will be difficult and expensive for one, number 2 when i turn on the computer the video cards fan whirs slowly up to full speed then slowly then back up for 5 times straight. i figure it is either a PSU issue or the whole darn thing needs to be replaced.

Please tell me I don't need to replace anything other than the PSU, my last PCI-Express cards are trashed anyways, I have no extras and no one else uses PCI-X in my house, I ran a cpu-id program while on the computer under my on board graphics and it sees the PCI-X slot and says there is a card in it, but the computer will not detect it at all.

I tried disabling on board and uninstalling the drivers but that did nothing, only things I have not tried is safe mode while on the on board graphics but so far nothing is even providing a partial solution. Sorry for the whole story involved here but this one is a dandy and is really just stupid.
