pc wont start

[dirtydave01]

my friend asked me to look at his emachines desktop pc, it won't switch on, i took the power supply out and checked it, it wasn't working at all, i've replaced it and the pc still won't start up, it's getting power because the halo is on around the switch but it just won't power up.

any help would be greatly appreciated.

Are the lights lighting up on the motherboard? Is the CPU fan spinning up? Are the hard drives spinning?

nothing is working at all, the only light that appears to be on is the halo round the wsitch but the motherboard lights are off and nothing welse is starting up at all.

Sounds like the motherboard is dead. If the power supply is working but nothing else is getting power than it has to be the motherboard.

seems like the mobo is shortcutting with the pc case. Try taking it out of the case and try switching it on. You may need to use copper screws
