I would have to agree with Nate on this one. your power supply is way
underpowered. I have a 750w power supply in mine. I had a 500w with my
8800 gtx but when I upgraded I noticed some minor and unpredictable
instability issues that were fixed when I upgraded to the 750w. That
said I also have a couple of other cards that are power hungry as well.
500w will work if that is the only card that you have if however you
have somethig like a tv card and a 3 or more hard drives then you should
really consider something around a 750w or more.
