Crazy weird booting problem.

[Codewiz]

About a week ago I shutdown my computer from within Windows XP(I had not restarted or shutdown in 38 days). I meant to hit restart instead of shutdown. Anyways, I pushed the power button and nothing happened. I started pulling the computer out and messing it with. After a few minutes, it started fine.

At the time I was in a rush and didn't investigate any further. Today I decided to see if the problem was still there. Sure enough, if I shutdown within Windows XP, I can't immediately restart the machine. I mean nothing happens. No fans spin, nothing. I figured this had to be a power supply issue. I used another power supply and I had the same issue.

I decided to test a few things, I manually shutdown the computer by holding the power button for 3 seconds while in windows. I could immediately start the computer back. The only time there is a problem is when I actually shutdown from within Windows XP. I can turn it off and on all I want using the power button to shutdown.

I updated the BIOS in the crazy chance that was the problem.

My system is:

Gigabyte 7VRXP
2400+ AMD
512MB PC2700
330watt Enermax PSU
Geforce 2 ultra video

I have never seen a problem like this. The confusing part is the fact that shutting down from within windows causes the problem.

Any ideas?

Check the Power Management Setting on Windows (inside Control Panel).

And look for what? I don't use any power settings. Hibernation and Suspend are off.

The other thing to think about is the fact that Windows has NO control over the BIOS boot process. There is just something weird going on. Like the ACPI going crazy at the hardware level. When the machine is shutoff using that chip the computer just won't boot.

Software can never prevent hardware from posting.
