Hi guys

got given an old pc with a 3gig p4 6800 ultra gig of ram etc.

just moved all the parts from an old case to a new case and thats all thats changed, power supply, components all the same

The problem is when i try and boot the pc everything except the usd ports and the video card is not cumming on although the fans are all working so the mobo is getting power but it seems the usb and agp slot is possibly not, all the fans i got ( cpu and one rear fan ) are getting power from the mobo and the light on the pci wireless lan card i got is o so thats getting power, im just getting no usb power nor monitor is not booting

any ideas what it could be?

just noticed when i quickly flick the power button the usb mouse i got flickers for a split second with power, could it possibly be that the mobo screws are shorting the board somehow?

i havnt got any of those small thin bits of paper? or whatever it is that sits between the screw heads and the mobo could that be shorting it?

its strange cos it was working and hour ago in the old case

just tried it outside the case usb is still not getting power, could the psu touching the case be shorting it?

right i tried the whole lot outside the case and even connected one of the usb extension from the mobo and plugged that in and still no power to the mouse....

sounds the the mobo possible gone or psu dammit!!
