Troubleshooting Computer Problem

by Wilmer

Troubleshooting Computer Problem: I am running Windows XP SP3 64Bits. I am having trouble in keeping the system running. It began by switching itself off when loading Windows; now after a few attempts, the computer operating system starts minutes later and then it switches itself off.

The temperature of the CPU starts at 26 degrees, then goes up to 34 degrees Celsius! This is when I look into the BIOS screen.

Any suggestions on what could be the computer problem or issue? Many thanks for your help.
