I am having a very weird problem.
After shutting down my computer normally, it refuses to start up again. Case fans, cpu fan all run, but nothing else. If I turn the psu switch off for 10-15 minutes, then on again, things seem to start up. Same thing happens if it goes into sleep mode, but I disabled this to get around it (I know, not a good solution).
I though it was a psu issue, but I tested it with a good multimeter, and all voltages are within ATX spec. Now I'm thinking it may be a mobo issue, but don't know exactly what to check for. Cleared the cmos, but no change.
Any suggestions out there?

Check ALL! connections from power supply to motherboard and other components make sure they are secured and locked. Also reseat memory modules, take precautions for ESD. Make sure power supply switch is in the off position.
