Build Issue for the techs

[Mitchen]

Hello all I have a brain tickler for you, I built a computer today for a friend specs are

MEC ATX 450w
Intel p4 3.0 2mb cache fga775 chipset
Intel d945gtp Mobo
1gb corsair value

upon initial power switch pressing there is no life except for the mobo L.E.D. Nothing spinning, nothing humming,i have tried unplugging everything, thought it was a faulty power switch but it worked on my fathers computer. what can be happening ? this has never happened to me before, i didnt use the fibre washers to secure the mobo.


any help or suggestions greatly appreciated.

regards

ok, I took the CMOS battery out and put it back in 1 min later SUCESS!!!

but then i can't turn it off without flicking the PSU power switch, after its off, i turn it on again to check the power switch, and it wont power up, until I Take the cmos battery out and flick it on at the back it fires up again.

whats causing this ?

keep in mind there is nothing on the hdd, i havent connected it too a monitor yet i took it home to work on its onboard graphics so it will be ok.

Do ou have another battery to replace that one? It would seem that the battery might be a problem.

Do you have another compatible power supply you can test with? I've never heard of MEC power supplies before.

Because of soft power switches you need to hold the power switch down for 6 seconds or so for the computer to be turned off with power being totally cut from it, its not like the plunger switches on older machines.

As cricket said, id also try another power supply if you have one.
