A bit more information is required.

What is the make and model of the PC?

What version of Windows are you running?

Does anything appear on screen or is it completely dead?

Do you have the Windows disc?

Did you do anything new to the PC just before this happened, new hardware, software, updates, scans of any kind including registry cleaners, overclocking, etc?

Download and install this to keep a check on your CPU temperatures. It can be set to display the core temps in the taskbar.

You didn't answer this: What is the make and model of the PC. If it is home built please provide the details for the motherboard, CPU, graphics card and Power Supply.
