Celeron 500 computer with more than 64MB RAM not booting into win2k? (Intel 810 Chipset)

[ndee]

I have here a computer, it's a Celeron 500, Intel 810 Chipset and with 64MB RAM. When I boot the computer with 256MB installed, a BSOD appears during the start which tells me that something with the ACPI stuff isn't working. I disabled everything that has to do in the BIOS with Powermanagement, but it's still not working. The OS is Win2k Advanced Server. When I put the 64MB RAM back in there, the computer boots normally.

Do you think I should make a clean-install and during the Win2k setup, choose "Standard-PC" instead of ACPI-PC?

Thanx for any help
