Help!!!

I was on the phone yesterday with MICROSOFT for two hours trying to update my computer from Windows 2000 Prof to XP Prof. All went well until it went to boot into XP and it's looping. It reboots, flashes XP and then reboots, flashes XP and gets nowhere.

Microsoft got me to the error section which were: 0x00000050 and page_fault_in_nonpaged_area. Apparently one had to do with an antivirus program that needed to be turned off and the other was the display driver.

Is there any way to update the display driver while it's rebooting in a loop??? And am I searching for an updated driver for the BIOS or the video card or both?

I appreciate any help I can get.

Thanks.You can attempt it from safemode although this may not interrupt the loop.
From a cold start power up and start tapping F8 as soon as you start it and before you see the Windows logo.
Once in safemode you can install/remove drivers.Patio,

Thanks for your reply......the Microsoft fellow put me in safemode.....it's still looping. He sent me an email telling me how I might uninstall XP but I have to get to a command prompt and I don't know how to do that? But on reading another Microsoft support page I'm not sure I can take XP off of Win 2000 Prof? We thought of replacing the motherboard, or taking out the harddrive, wipe it clean and reinstalling WIN 2000 Prof (I have the CD). I have checked the drivers for the motherboard and they all seem to be compatible with Win 2000 and XP. So when my computer was working fine in Win 2000 and all we did was update, why WOULD it not work for XP??

How much info do you need from this drive ? ?
The safest method is to remove the drive and hook it up as a slave in a known working system and copy/burn the data you need...
The 2nd thing to consider is that this may be a hardware issue.
Remove a side panel and double-check all connections to make sure they are snug.
Also look at all fans/heatsinks as well and make sure the fans are all operative and the heatsinks are not clogged with gunk.
A can of compressed air works well cleaning out the gunk.
Use a QTip to hold the fan blades in place while blasting them to PREVENT damage...
After doing the above i would run the HDD diagnostics on that hard drive available from the drive manuf. site before replacing it in the offending machine.
You could also run chkdsk /r in case it's a Windows issue.
When your data is SAFELY backed up let us know how you want to proceed.
If you do want XP on there it may involve wiping the drive; re-installing Win2k and starting over.
Let us know.

BTW Welcome Aboard. And on your next post provide as much info on the machine in question as well....Patio,

Again, thanks for your answer, thought you and others would be interested in what happened. I had a friend check out my computer and the first thing he noticed was that I had a Iomega zip drive attached. He detached it and XP loaded just fine. Only problem is that on booting up now I have two XP's listed, the PARTIAL one and the full and complete one. Now I'm having problems with software and another call to Microsoft today.... They tell me the only way to get rid of the partial, looping XP is to reformat the drive, reload Windows 2000 Prof and then reinstall the upgrade XP Prof. So I guess in the long run it will be for the best, wipe the slate clean and start over. Yep. That method will produce the cleanest results...
Thanx for stopping back and giving us an update...
