I recently had this same problem on my boss's computer at work on a Dell with an NVidia card. After some troubleshooting and examination, I found 2 capacitors on the card had ruptured, which obviously would cause some problems. The capacitors used on these cards have been known to rupture like this for no reason. If you remove the card, it should be obvious if any of them have failed. Look for the small cans on the board and make sure they all still have flat tops with no fluids or crusts on top. If they have failed, you have 2 choices: replace the card or replace the capacitors (only if you are VERY good with a soldering iron).
