Had a similar problem a while ago. With my PC there is a 'bleep' just after I press the power on button.

This 'bleep' stopped and I have problems booting up my PC and when it did it crashed pretty soon after. My MOBO was faulty and needed replacing.

No beep at all. Unplug everything from the motherboard except the CPU with heatsink, power connector, power switch and case speaker. You should then get and error beep (usually a series of beeps). Still no beep, unscrew the motherboard from the case and rest it on an insulating surface such as a sheet of card. Still no beeps, then you have a faulty PSU, motherboard or CPU. The most common is motherboard or PSU. You can only tell by substitution, although you can buy a PSU tester such as click here
