Been about a year since it was delivered, but my Dell XPS M1330 has to go in to the hospital now...
Apparently Nvidia shipped some bad mobile gpus that were degrading over time with use.

Thing is its undercooled, with a fairly gimp fan, and that fan wasn't very reliable, with it sometimes hitting 80-90C+
CPU temp, and probably much higher on the GPU.
The new bios that supposedly fixes the overheating issue isnt much of a fix... it just basically turns the fan on high constantly. So it makes my quiet laptop noisy. To fix a design defect.
