Installing ACPI Support

change the type of PC in the device manager, from standard to ACPI

<i>It's always the one thing you never suspected.</i>

Where/How exactly is this done? I'm in the Device Manager, and under Computer, there is Standard PC. I can go into its properties but it doesnt say anywhere how to change it. In the properties there is IRQ Steering. There is no ACPI driver when i click update.

You can't just change from standard to acpi in device manager. You have to do a repair install. First, check to see if you really do have standard.hal under computer. If so, you then have to place your XP cd while it is loading, press F5 and select ACPI or Uniprocessor from the list. Use the arrow key or mouse to scroll the list. After the screen stabilizes, you have to select enter to install XP. On the next screen, select repair XP. Make sure all your drivers are XP compatible by disabling them one by one if this still doesn't work. Finally, before you do any of this, make sure your CPU supports ACPI. I'm pretty sure that it does but check first. The motherboard definately is ACPI enabled but check BIOS anyway.

good tip. Is this something new in XP? Because I know I've done it in the device manager under 2K...

That was the way it was described at Microsoft support. I don't know about 2000 but XP needs to be done the way I posted it.
