I perviously posted but now I have a little bit more info. The problem was right after Win2k Pro loads (right after logo splash screen) I get a BSOD. It says:

*** STOP: 0x00000050 PAGE_FAULT_IN_NONPAGED_AREA

Looking it up in Microsoft's site gave me this:
Bug Check 0x50 PAGE_FAULT_IN_NONPAGED_AREA, defined as 0x50, is issued if invalid system memory is referenced.

So my question now is, what is going on with "invalid system memory" being referenced, and how do I fix this?

I have also been looking it up in the related Microsoft's site. Let’s read, from what I see, everything is clear there:

<A HREF="http://msdn.microsoft.com/library/en-us/ddtools/bccodes_4w6f.asp?frame=true" target="_new">http://msdn.microsoft.com/library/en-us/ddtools/bccodes_4w6f.asp?frame=true</A>

<font color=blue>"<b>Cause</b>
Bug check 0x50 usually occurs after the installation of faulty hardware or in the event of failure of installed hardware (usually related to defective RAM, be it main memory, L2 RAM cache, or video RAM).
Another common cause is the installation of a bug-ridden system service.
Antivirus software can also trigger this error, as can a corrupted NTFS volume.
<b>Resolving the Problem</b>
<i>Resolving a faulty hardware problem:</i> If hardware has been added to the system recently, remove it to see if the error recurs. If existing hardware has failed, remove or replace the faulty component. You should run hardware diagnostics supplied by the system manufacturer. For details on these procedures, see the owner's manual for your computer.
<i>Resolving a corrupted NTFS volume problem:</i> Run Chkdsk /f /r to detect and repair disk errors. You must restart the system before the disk scan begins on a system partition. If the hard disk is SCSI, check for problems between the SCSI controller and the disk.
<b>Comments</b>
Typically, this address is in freed memory or is simply invalid.
This cannot be protected by <b>try - except</b>; it can only be protected by a probe. "</font color=blue>

I think that Microsoft's comment about SCSI we can extend to an IDE RAID controller and disk(s).
And there is a more simple explanation on one of possible causes of the problem:

Thanks Nick... the problem was the video card.

Good to know you've solved the problem. Just curious, what card?

There's known issue with nVidia Riva 128 chip set in general giving such error message:
