After my computer has been on for about 1/2 to 1 hour it resets with no warning. Upon restart there is no error report and then after that it resets again within the first 10 minutes. Upon restart i check the CPU temp and it is roughly 60-65 degrees C. I have reinstalled windows once to try and see if it was a software error. The installation was succesful but the windows CD was unable to copy over all of the files. Reinstallation has not fixed the problem.
My only real theory as to the problem would be the CPU temperature. If i got a more powerful CPU fan would it fix the problem? or is it too little too late and the processor is already on the way out? What are the chances a complete reformat will fix my problem?
