Solution:
Unlike other components in your computer, when the CPU is dead, it simply will not work. When this occurs, says Intel spokesperson George Alfs, �€�the system will look totally dormant. You might hear the hard drives start to spin, and you might see indication that power is being supplied to the motherboard, but you�€@trade;ll see nothing on the screen.�€� The PC might not even begin its POST routine. [The testing portion of the BIOS (Basic Input/Output System) is POST (power on self test), a series of diagnostics that helps you determine whether everything is OK with your computer, or, if it isn�€@trade;t OK, what could be wrong.]

This seems cut and dried, but when it actually happens, it seems impossible to simply presume that the CPU is at fault. Sure, a faulty CPU will prevent a computer from starting up, but couldn�€@trade;t there be other causes? Yes. When a computer refuses to start but the power light illuminates, the main culprit is usually the PC�€@trade;s PSU (power supply unit). If you haven�€@trade;t made any recent upgrades to your computer, try replacing the PSU. Consult the PC or motherboard manual to make sure the new power supply is appropriate for your system. If the problem occurs after making an upgrade (such as replacing the CPU), consult the PC or motherboard manual and determine whether the PSU is properly connected and set at the correct voltage. If these solutions don�€@trade;t work, try replacing the PSU. For information on how to replace the power supply, please refer to the article below called "How To Replace A Power Supply".
