Bad mobo?

This is a follow-up to an earlier post. I'm having a problem with the start up/shut down. I originally believed the problem was the switch or power supply. Here is the situation:

- the problem started with the computer immediately restarting after shut down. I had to pull the plug to shut down. Then it wouldn't start from the switch. It would start by flipping the power supply switch and unplugging/replugging the power cord. It usually takes 6-10 tries to get it started.

- I reversed the lead for the switch on the mobo. It didn't help.

- I jumped the switch contacts and it didn't start.

- the switch does turn the computer off when pushed.

- a second psu does not fix the problem.

I guess the problem is a bad mobo. Does anyone have any other ideas?

Thanks,

Sherm

Just a long shot, but have you tried checking and making sure that your heatsink is making good contact with your CPU and that you have a good thin coat of compound on the CPU?

It sounds like an incorrect ACPI setting. In the power management section of your BIOS, try setting everything to default. Also, does your computer read as an ACPI PC in Device Manager like the pic below?
