A few possibilities:
Overheating
Malware (ie, virus)
Memory problem
Possible solutions:
Have you cleaned inside your computer lately? Use caution, and a wrist strap, when doing this to avoid damage. Make sure all the fans are clean, running, and not making any funny noises (Power Supply fan, CPU fan, and case fan).
Follow the recommendations and instructions in the links below (in my signature block) to help protect and cleanup your system.
Does your computer report the actual amount of RAM you have installed? Have you added any recently? Sometimes just removing RAM and reinstalling it helps.
