Windows bluescreen error - Mode-Exceptin_not_Handled

Address BFEA0D16 base at BFEA0000, DateStamp 3d25bc59 - Mup.sys

I keep getting this error and I have been unable to find any resolution to this problem. I am running Windows 2000 Pro with Symantec Antivirus Corporate, Novell Netware Client 4.8, Office XP and a host of other applications. If anyone has any info that could point me in the right direction it would help a lot. I am stumped.

The error happens during normal operation, at startup, or during a particular application?
Use Control Panel, Administrative Tools, Event Viewer to expand the exact error.

The error is in the MUP.SYS file. Try this thread from Annoyances.Org:

Hope this helps.

The error happens just randomly as far as I can tell. Sometimes when I'm typing an email, sometimes surfing, sometimes when I'm not even doing anything. It also happens frequently at shutdown.

I did look at the thread at annoyances.org. I tried disabling mup and that didn't help.

What exactly should I be looking for in the event viewer? There are no yellow or red lines that deal with mup.

The full error code you're getting is as follows:

Stop 0x00000001e (0xc00000005,0xbfeaed16, 0x00000000, 0x00000000) KMODE_EXCEPTION_NOT_HANDLED
Address: bfeaed16 base at bfeae000, datestamp 3e25bc59 - mup.sys

Basically it means that the Windows Kernal has detected an illegal or unknown processor instruction that came through the redirector program known as MUP.SYS. Unfortunately there are a lot of things that could have caused this, most of them being hardware related (like a bad CPU, bad memory, or bad motherboard). What you need here is a system diagnostic program that can test various pieces of hardware and rule out if anything may be going bad.

Short of that, try a full virus scan (with updated definitions) and possibly an updated spyware removal program (such as Ad-aware or Spybot Search & Destroy). This would at least rule out any malicious program activity.

Try booting to the system menu and choose Last Known Good Configuration. This would help rule out any recent changes made to the system.

Hope these things help.

As a start, do an extended memory test with the Microsoft online crash analysis memory testing utility:

Well the first thing I ran was a virus scan after updating definitions and I was getting worried because it would reboot frequently and I thought I'd never actually get the whole thing run. It finally ran and there were no viruses so then I ran Spybot and nothing other than a few bad cookies there. I also ran the system diagnostics from Dell that are on the utility partition and they too found no problem.

What I don't understand is that I still got the errors after I disabled mup. If its disabled then how can it be causing errors?

Just for the heck of it I ran the memory test from Microsoft you linked to and that didn't produce any errors either. Finally I just copied the mup.sys file from my laptop and that seems to have fixed the problem.
