grab my external drive, back up all of the items in "my documents", "my pictures", and "my music" in that order. screw videos. while doing that, i would try to figure out what the problem is with my computer, if its the cpu, or memory, i would take note of that and order a new one, if it was my motherboard or gpu i would remove my cpu, memory, and hard drive and sell them (keep the hard drive though) then buy a new laptop.
