DWM.exe crashes with UAC

Hello all.

I've got an interesting problem. When performing some very specific actions
that engage UAC (i.e. snipping tool, running unknown [to Windows]
applications), about 50% of the time, dwm.exe crashes. Now, since this is
protected from being debugged (understandably), I'm having trouble
diagnosing/solving it. Here are my specs:

Intel core 2 quad (Q6600)
4GB RAM
Vista Ultimate 64bit
Dual nvidia 8600GT video cards

I've updated all of drivers, so I don't think this is the issue. This first
started happening (though not immediately) after I overclocked my CPU (back
to defaults now, but still happening). Here's the full text of the event log
msg:

Problem Event Name: APPCRASH
Application Name: Dwm.exe
Application Version: 6.0.6000.16386
Application Timestamp: 4549b7e9
Fault Module Name: msvcrt.dll
Fault Module Version: 7.0.6000.16386
Fault Module Timestamp: 4549d2e1
Exception Code: c0000005
Exception Offset: 00000000000017db
OS Version: 6.0.6000.2.0.0.256.1
Locale ID: 1033
Additional Information 1: c541
Additional Information 2: cee0f0a18f48f40265d6a5cb5749171e
Additional Information 3: 23b6
Additional Information 4: d9a48ac0288f7eddc923475806eaae11

I'm pretty stumped and would love some direction. Thanks.

Matt

Just figured it out, but still left a bit scratching my head. My Experience
Index needed to be refreshed (obviously after an overclock). Not sure why
this would cause this specific behavior, though.

Oh well, maybe this will help someone else that's banging their head against
the wall.

UPDATE (for those interested): This did not fix the problem. UAC acted as
normal for about an hour and then it started crashing DWM.exe again. So I
guess I'm still looking for some hints/suggestions/anything.

Much obliged.
