My PC is fubar. When I turn it on I can hear the drive spin up and the PS fan come on. The normal boot sequence takes about 90 seconds. The drive clicks for about 10 seconds and then the boot stops. The monitor does not show anything. I assume that it is not a HDD problem or I would get the FDD error from the bios, and it can't be a monitor probelm or esle it would complete the boot sequence. All I can think of is that there is a problem with the motherboard or with the power to the board. I don't know how to test the PS and see if it is working properly. The fan and peripherals are powered up but since the motherboard has quite a few more connections I assume that whatever part of the PS supplies the board may be faulted while the rest of it may be operating. Please tell me how to test the PS output to the Mother Board. I have a voltmeter but don't know what leads to check and wether to check them to ground (the frame) or to another lead.
