Windows 7: Graphics card and PSU problem.

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?

Hi

Welcome to Seven Forums.
Mixed opinion on the issue as some users have been able to use a 250w brand-name PSU to run similar versions of the card you have - note however that this would be dependent on the card-vendor and the PSU used.
Others have not had a good experience with a no-name PSU with more serious consequences.
As for your card, recommend that you remove the card and try it on another PC (possibly a friend's) to see whether it will still work - ideally the PSU for your card should be "Minimum 300 Watt power supply (Minimum recommended power supply with +12 Volt current rating of 18 Amp Amps)". If it still works, you could then upgrade to a better PSU.

Hope things work out and regards

Alright, ill check if it works in another computer, then upgrade the PSU if it does, thanks.
