since ur PSU.power switch are ok then the culprer is most prob ur mobo/processur/ram.

the only way to check it would be with spare parts. why dont u take it to some other computer shot and get it checked.

are u sure the power switch on cabinet is working, just use his cabinet and check, if sure then power switching thing on mobo should be gone, is there any led on mobo that glows.

check whether any of the front panel pins are shorting with each other if yes seprate them with screw driver

ya i have checked the ram by changing it to one of my friends.
and i knw culprit is either mobo or proc. was taken it to one shop but he told me leave the pc with him and next day he will tell me what is at fault.
