My main system stopped booting two weeks ago, so had to move back to my previous system. Fortunately, a lot of my stuff was in Dropbox, so after a decent interval, many of my files were available on the previous machine. Yay Dropbox. There are, however, still a few files on the dead system I'd like to get. Today I took that system apart, popped the fan off the CPU, and found dried thermal paste. Hmm. It's possible that the CPU might be cooked (I was away during the Final Crash), but on the off chance that it just over-heated and shut down (does that even happen?), I know I need to clean off the old thermal paste (Q-tips and rubbing alcohol) and apply new. Strap the fan back on, power up and see if it boots. Best Buy only ships this on-line, and Canada Computes doesn't seem to stock it. Can anyone comment on where they get thermal paste? I could wait for delivery, but it would be great just to get the stuff and move on.
