So I've got some problems with freezing, usually when playing video games for about 10 - 30 minutes, even basic video games (Bookworm Deluxe, The Incredible Machine, Runescape). Anyhow, it ran these gaves fine before until recently. I had the same problem in the summer and it turned out to be overheating. I fixed it, now it's come back and it's during the winter. Here are some specs.
800 megahertz Intel Pentium III
Aladdin TNT2 Videocard
(I'll post more information if needed)
I checked the CPU temperature after the computer froze and the CPU temperature was 90 degrees which seems like a lot. Is there overheating? Also another question (since I'm not too computer wise), I have 240mb of ram but the most free memory I'll have is 110mb, what's with that?
