hi!!!

my computer just doesn't start... :cry:
the green LED of my MB (asus p4p800) is on, but nothing else moves (fans, drives, disks, ...)
i've tried connecting the two pins of the power switch in the MB with a paper clip, but it didn't work...
what can I do now??? can I try anything else? is it the MB? is it the PSU?

thanks

closer

With the PSU unplugged and switch off, Pull the 20 or 24 pin Plug on the mother board and with your paper clip, In the plug for the motherboard short pins 14 to 15 on a 20 pin plug or short 21 to 20 on a 24, Plug the PSU in and turn the switch on if the PSU starts then it is in the motherboard start circuit or a short.
Caution: Just do this long enough to see if the PSU starts then shut it down it can damage the PSU if it is left on to long.

thanks

i've just tried what you said...

unplugged the PSU, shorted 14 and 15 pins (it's a 20 pin connector) and turned it on again... nothing happened...

so... the problem should be on the PSU, right?

thanks

It might be dumb..

It might be a dumb, "no brainer", but I wonder if a dead CMOS battery might cause a system to fail to POST.

Might be worth a try to replace it.

Also, I bet you could stretch the cables from another PS (even if it's inside another case) and see if the machine will at least kick on.

That might narrow things down a bit.
