Help. Computer shuts off when On-Line

The past 3 weeks my computer has begun shutting off when on-line. It seems
to happen mostly when playing games, etc. on Disney's site and similar
sites. It also seems to happen more often if the sound is on. I can't
think of anything new I added, etc. that could account for this.

Any help would be greatly appreciated. It's annoying as can be.

I dont know but it sounds like the more the CPU is doing the more it
shuts down. Could the CPU be overheating?
