If I were you, Mamamegs, I'd take this approach:
That particular message
"mismatched number of KeEnterCriticalRegion compared to
KeLeaveCriticalRegion"
you're zeroing in on is generally from the addition of new hardware
that is causing a problem--perhaps via it's driver(s). See:
www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/w2000msgs/1117.mspx
That said I'd do this:
1) You can often prevent a gamut of BSOD's from a panoply of causes
by opening up Driver Verifier Ref.
How to Use Driver Verifier to Troubleshoot Windows Drivers
http://support.microsoft.com/kb/q244617/
and
1) Disable deadlock detection
2) Disable *the inspection of and note this does not one scintilla
impact the functionality of the software drivers of your antivirus
program.
Simply put again, disble driver verifier's inspection of your
software drivers for whatever antivirus progam Mamamegs has chosen to
use. That program is from a well known vendor. It's not going to
pitch in drivers that will harm your system, however disabling the
inspection of them by driver verifier and disabling deadlock
detection often prevents the BSOD's you've been getting. I have
found it to be very very effective, and MSFT has not come around to
showcasing it or emphasizing this yet but some of us are trying to
change that.
Many of the population never learns there are software drivers in
their equations as well as hdw drivers.
If that doesn't do the trick, try running the Startup Repair Tool
(you do not have to have a BSOD no boot Vista to run it and get a
repair from it--this may solve your problems:
You run the startup repair tool this way:
