I am no expert on hardware failures, but you may consider cleaning the
dust out of your case.  Try running the computer for a while with the
case open and see if the fans on the graphics card and CPU are spinning.

Good idea.  It does sound like a hardware problem.  You didn't do any
major software changes, though, did you?

I have never tried them, but I know that there are many programs that
can diagnose hardware problems or at least make the hardware work
extremely hard and fail if it is defective.

Some words to search are memtest or mem86 and GIMPS (Great Internet
Mersenne Prime Search) torture test.

This sounds like a graphics card problem.  Try turning off X and doing
something non-graphics intensive like compiling a kernel or running a
torture test for GIMPS.

Good luck.
