Its amazing the way computers revive themselves... I got called into work two weeks ago because a machine suddenly died. They couldn't get it to boot. When I got in, I turned it on and it worked perfectly :shrug:
Yesterday morning it wouldn't respond at all. this afternoon, it booted, but crashed soon after. Now, it seems to be working pretty well but the screen has flashed black a couple times. Tomorrow... I expect it will be working better than before at this rate
