Hi

a bit stumped with this one, a mate asked me to have a look at his PC which has never worked since he got a friend to build it for him.(feel sorry for him as it cost nearly a grand awhile ago).

When you turn it on there's nothing apart from a red led lit in the psu, and 2 leds lit steady on the mobo, no fans, no cpu fan or sign of life.

The mobo's a Abit kn9s and has a 24 pin atx socket, psu's a X-power 450 w but states on it pentium 4 ready?

the mobo pin outs for atx power are 24 pin, this power supply comes witha 20 pin plus the four pin, but the wiring looks different on the 4 pin psu lead, are these different for AMD, and Intel set ups? are there differing voltages on the pin outs, if so this guys possibly fried it

any info appreciated
