My feeling is this could be a faulty power supply.
You should try a new PSU first.
How old is the hardware?
It's a two-year-old box. Yes, it could be the PSU, but in my
experience when they go bad it manifests in more than one way.
I've had a couple of them fail over the years.
At any rate, the guy I took it to will zero in on it. I'll have a
definitive answer tomorrow. If I'm lucky, a full internal
cleaning of the graphics card and some new thermal paste will
solve it. I'm usually not that lucky, though :-)
