Do I need to replace my CPU?

  1. At random, XP will restart on its own. The computer was built less than 2 years ago and I'm not quite sure if it's a software or hardware issue. AMD 2600+, 1.9 ghz, 512mb RAM, windows XP, radeon 9600 graphics card.

    I find the computer crashes when it's put under a heavy workload. For instance, I opened Spy Bot S&D to rule out any infections and within 30 seconds of running the application the computer restarted. This occured back to back just moments ago. Other times I am using WORD or browsing. This has been occuring for more than 4 months now.

    I've ran a CPU application to max it out and again the computer restarts. It occurs everytime I run the program.

    I also monitored my RAM while it performed and only 50% was being utilized.

    How do I know it's the CPU and not the Motherboard or HD?

    This isn't "Clue" we're paying, you say?

    Spybot uses 100% of the CPU. Your box could be entering thermal cutoff.
    Use canned air to clean out the CPU/ heatsink, and just for good measure the rest of the insides as well.
    Find out if your board has hardware monitoring and find what the critical zone temperatures are. You may have to install either the board manufacturers monitoring software or a utility like "Speedfan', available here at Techspot.
