Carl,
did your problem started right after you upgraded to XP Pro?

I'm almost sure the problem is driver conflicts...
Have you updated ALL your drivers when you upgrade to XP?

Also, what's running behind Micro? Try to close your antivirus and any other program, make certain Micro is running alone.

I suggest you first try these options & if no changes I suggest you disable both DMA's (HD & CD-Rom). With XP they both enable by default.

I've notice that you install using the NTFS so your running the NT plattform which is more stable than 98 but you might have old software or driver that might not run on NT.

One last thing, did you do your Windows update? Do it first

Good Luck
