It sounds like you have an overheating problem, very possibly a bad fan or dust clogged heat sink and/or fan. Open case and inspect, blow dust out with compressed air can (Radio Shack, computer store, Staples,etc. Then turn on system and observe fans (CPU fan, rear case fan, and power supply fan would probably be the minimum, unless very old). Blow additional air through any fans not turning. Replace any fans that are not operating.
Install a program called SpeedFan and observe temperatures. All reported temperatures should be in the 30's or up to 40's (Celsius) at idle and typically 10 to 15 deg higher while running a few things for a while. Report back findings and readings and if it helped. If you really want to know what your temperatures are currently, you can install SpeedFan first and get a baseline on how hot it really is now and how high it goes before it cuts out, BUT stop it Immediately if you get into the 90+ degree range to reduce the chance of permanent damage.

You have to be a little bit crazy to keep you from going insane.
