Recently (last couple days) my PC has been acting up - the display turns off shortly after powering on the computer.
Windows loads as normal, and I start using it, but somewhere in between 2~20 mins the display just cuts out, and doesn't come back. Sometimes the sound cuts too, sometimes it continues.
I am thinking it may be a power supply problem, as it is a fairly cheap PSU, and a fairly power hungry card (GTX 260).
My gut says it's a PSU as well (especially since the sound cuts out sometimes, keeps working others). Just because it doesn't overheat doesn't mean it's not failing.
If it's not a huge burden I would try getting a new PSU, even if that PSU isn't the problem, it's more likely than not that someday it will be a problem. (Tom's had a good article a while back about some scary stuff with cheap PSU's)
This is a great PSU if you would like a recommendation: http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It's a little pricey for the size, you could probably go cheaper, but be cautious how much cheaper you go because there is a pretty strong relationship between cost and quality.

I agree with DkScribbles that it is most likely your PSU. Go for a new one, probably something that is a bit more powerful, like around the 550-600 Watt Range. Maybe ever more juice would be better.
