Two nights ago my computer was locking up, then shutting itself down. I suspected the problem to be the hard drive, or RAM. RAM is being tested as I write, and has passed 1 pass of MEmtest86+ off the Ubuntu live CD so far. I can still access files on the drive.

Seatools Results:
Short Drive Self-test - FAIL
Long drive self-test FAIL
Short generic PASS
Long Generic PASS
