Ok so i've gotten this BSOD a few times now.
Running windows service pack 2 32 bit.

IRQL_NOT_LESS_OR_EQUAL what does it actually mean?

I googled around and ended up downloading windows debugging tool. After figuring it out I checked a minidump.
Heres the results:

BugCheck A, {6c, 1b, 1, 8207ca66}

Probably caused by : win32k.sys ( win32k!SURFACE::Map+47 )

Followup: MachineOwner

What is the file win32k.sys for?
What does the rest of it mean?
How can I stop this from happening again?


Thanks in advance.
