Looking at a friends pc for him . Can't get it to power up. I have checked the obvious such as power from the socket, fuse in the plug, cable attachment and have even swapped out the psu with a known good one. Still to no avail Am I missing something ? I try the on button but nothing happens no lights, no sounds it appears to be dead. Could the cpu be "cooked"? Any ideas greatfully accepted.
Thank you
Pavel

Strip it down to the minimum. Disconnect any cdrom \ dvd drives. Take out all pci cards, but leave the graphics card if it has one. Just leave the bootable hard drive, 1 stick of memory, cpu with hsf and the graphics device. Give that a whirl.

If that will not boot, then check the psu power connector to the board and also the power lead from the case to the motherboard ( from the on \ off switch.

if that will not boot, take the motherboard out and place on a sheet of cardboard, see if it will go to post,it may be shorting on the case.

I presume that you have also tried pressing the "RESET" button if the PC has one. It could also be that the ON/OFF switch is faulty.

Note also this paragraph from the links pn the left

which could also be the reason the PC will not start up.

There is also the possibility that the power switch is damaged. In an ATX system (practically any computer made since about 1998) the power switch is a momentary contact switch that briefly short together the 2 power pins on the motherboard, so you can test the switch either with a multimeter, or you can touch the 2 pins together yourself. With some computer cases the switch can be pushed out of position by the button on the front of the case. I have repaired one of these by removing the front panel, repositioning the switch and locking it into place with a Tywrap and hot-melt glue. The power switch only works at 5 volts, so there is no mains voltage hazard.

The 20 pin connector to the M/B is shown on this webpage with info on pins click here
