PC Wizards, help needed! NickT etc :-)

OK today my Dad was on the PC downstairs (4+ years old) doing a disk clean-up on the C drive (comp only has this one hard drive) and all of a sudden everything goes dead - computer and visuals. As soon as he shouted to me I was like oh I bet the power supply has gone, but it hasn't, its still feeding power to the motherboard etc - there's an LED on the m.b and its still coming on. When you press the on button on the front of the tower nothing happens. Can anybody think what might be up? Cheers in advance!

Could be anything from the power switch, power supply, processor/ ram (although would expect error codes bleeped at you) etc.

You could use a multimeter and check for voltages.
Remove 4 pronged power plug from a hard disk/ cd-rom and see if you get 12v between yellow and any of the black, and 5v between yellow and any of the black cables.

You could chance a new power supply for £20.
Ensure you get one with the same wattage (power) rating or replace with a higher rated one.

Good luck.

Hi mate, cheers for the advice! Last night I pulled out an old psu from an older pc and the computer downstairs fired up fine, so it was definitely just the psu that had blown. Went to PC World and got a new one this morning, Im gonna fit it later! Many thanks Nick again!
