Yours sounds a bit similar to a situation I had.

I had happened to on a m1330 dell laptop with an defective batch of 
nvidia 9000-series gpus that were popping off the bga on the mobo.  
Linux would do that to me, basically hit gdm, login, and when compiz 
kicked in and composited the desktop against the gpu, it would lock or 
just throw crazy colors on the lcd.  I could run it in "classic" at the 
time without compiz, which would work, which didn't call the gpu.  Had 
to rma the mobo under an extended warranty because of the gpu after some 
research.

Why I'd mentioned the gpu.  If integrated, you're screwed, if not, try a 
different card.  I find gpu's die in ugly ways, not always apparent, and 
I've seen linux get wonky with a few on my desktop before I get annoyed 
to attempt to rule it out.
