hi wondered if someone could help me:

ill explain my problem, ok recently i purchased a new atx tower and when i switched turned on the power button and nothing... made sure i got the correct front cables and both motherboard power cables where inserted, so maybe board faulty had it for 3/4 years. so i bought a new mobo its a winfast nf 4k8ac thinking that this would solve the problem... but nothing done some trouble shooting and narrowed it down to the psu, at this point pressed power button on the tower fan would move but just cut out, maybe short circuit but dont know, bought a new psu and same thing now im getting a little frustrated anybody like to talk me through would be appreciated alot... i can tell you the spec of pc- amd athlon 939 3200+ - 570wt trust dual fan psu - NF 4k8ac motherboard - nvidia 7600 GT - 2gb ram - 2 matched pair corsair - 2 single ram all 512 - any suggestions ?

HI the best thing to do in this situation is to remove all hardware form th PC case. On a wooden desk or none metalic surface plug the power supply in to the mainboard and fit the CPU and RAM plus the CPU fan plug in your monitor. No harddrives or cdroms no extras at this point then where you plug the power switch in to the mainboard 2 pins cross them for a second with a screw driver and see if the PC boots to a post boot screen.

nope nothing man, the fan still spins a little you hear the psu like starting to spin but just cuts out, could it be that the cpu is shorting out the power? had it 4 like 3 years but not going to buy a new 1 until i find the problem... anything else you suggest?
