XP shutdown issue

I just installed XP home, and when I try to shutdown it goes to the initial shutting down screen, but eventually locks up with no response whatsoever from the keyboard. When rebooted, it does not detect an improper shutdown. I think it may be due to my motherboard, which has both AT and ATX power connections, currently using an AT case/power supply. I'm guessing Windows thinks it can shut down the system when it really can't. I've tried turning off ACPI in the bios, but then it won't even start up. I figure there's either a bios change, or registry edit to force Windows to go to the "OK to shutdown your system" screen.
Motherboard is Epox MVP3C or MVP3C2, AMD K62. All points to the first fix

I apologize for leaving this go so long.
Anyway, I think the problem goes back to having a combo AT/ATX motherboard and the AT style case/power supply. I think I'll just spring for a cheap ATX case/PS as a Christmas present

Your on the right track with disabling ACPI.

First, you need to remove ACPI from device manager inside XP.
(Administrative tools, Computer management)

Then, if you are using an AT power supply, you must not use the switch contacts on the motherboard.
Also, make sure the jumpers on the motherboard for AT/ATX are set correctly.

Upon re-boot, enter BIOS setup, and disable ACPI support.

Alternately, for around $5, you can get an AT/ATX power switch for your case.
For $20 or less, youcan get a 250Watt ATX power supply.
Install both, and have ATX power operation with automatic shutdown.

Did you check out service pack 1 for XP? It does have a fix for some kind of shutdown problem. Download the service pack and see if it resolves this problem.
