Laptop’s acting up again

It’s doing the exact same thing it was doing a few months ago, basically completly locking up randomly. I personally believe it’s overheating. I received the shipping box from Toshiba today, but I need to backup all the data on it before I dare ship it in for repairs. The problem is, as I’m copying the data the thing keeps locking up on me. I had to reduce CPU speed from within power management to bring down the operating temp, but now the thing is performing like a turtle.

All this made me realize that I have 2.7 gigs of digital pictures stored on it. Probably a good idea to back it up anyways.
