Windows 7: Intermittent BSOD - MUP.SYS

Intermittent BSOD - System Service Exception(3b) & mup.sys

Within the last 4 weeks, I've been getting complaints of intermittent BSOD on 7 PCs. It seems to be more frequent on two of them. I've inspected the memory.dmp files generated and they all point to the mup.sys file causing the issue. I read an article on here on how to run the driver verifier, so I tried that but I'm still not sure what may be causing the crashes. I uploaded an XML file generated by the crash and and memory.dmp with results after having verifier enabled. Any assistance would be greatly appreciated!

An exception happened while executing a system service routine.
Arg1: 00000000c0000005, Exception code that caused the bugcheck
Arg2: fffff880019d40cd, Address of the instruction which caused the bugcheck
Arg3: fffff8800547d8e0, Address of the context record for the exception that caused the bugcheck
Arg4: 0000000000000000, zero.

Hi rikper,

Please upload dumps of all systems having BSOD issues, preferably with Blue Screen of Death (BSOD) Posting Instructions

Run MemTest86+ on the system where the dump is coming from.

Intermittent BSOD - MUP.SYS Diagnostic Test Intermittent BSOD - MUP.SYS

Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 7 Forums

Note   Note

MemTest86+ needs to be run for at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero errors here. Even a single error will indicate RAM failure.

Make a photo of the result and post it.

If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.

I ran HP hardware diags and no issues. I also ran the memtest86+ diags and no errors.

Here is another dump file from a different computer. So far these are the only two that have had a BSOD since I enabled verifier. I have not run the memtest diags on this one yet

That sheds some light on the situation for this system.

Check for this system for network driver updates and check Symantec/Norton for software updates.
You may also want to check for BIOS updates.
