So i recently bought a computer online and installed an 8600gt into it. It has a 250w power supply, so i thought it was a little bit too low, but i left it anyways. After 2 weeks, the video card just stopped working. When i plug my monitor back into the motherboard, the on board graphics, the computer works, but when i plug the monitor in through the graphics card, it doesn't work. Its weird though because the fan on the graphics card is still going. Any ideas? If i upgrade my PSU will it fix this and my graphics card will work again?

Hello and welcome to Bleepingcomputer.

I have seen this model number show up a lot in the forums lately with a problem for some reason or another. I am not exactly sure what's up with that.

Some results were RMA issues, others were incorrect BIOS settings, some were resolved by rechecking that the card was properly seated in the slot and the last one is the present PSU did not supply enough Amps on the 12 v rail to power up the video card.

I would say for the quickest solution, is to try re-seating the video card in the slot to be sure it is making full contact, if you need to, use a toothbrush in the slot to make sure nothing is in between the contacts preventing a good connection from being made.

You may want to check the VGA port for a possible poor or loose solder joint, as that can happen from time to time.

If all else fails you should return the video card while it is still under a possible warranty and hope the replacement card works flawlessly.

Bruce.

I did take the card out, i fully cleaned it with those pressurized air cans, i cleaned the slot out, i put it back in and it still doesn't work. Ive had the card for about 3-4 years now since this was from my old computer, so i don't think it has a warranty anymore.

Just for the record, the manufacturer suggests a PSU with 350W, and a 12V rail @ 22A.

Alright, so is it too late to change my PSU to 500w now? Or if i buy a stronger PSU will it work again?

I suspect that from what you have written that the card has failed. You want to try this card in another computer with a larger PSU to see if it will work there.
