generally, a bugcheck in win32k.sys is not a graphics problem.
win32k.sys is a common target of malware and windows now does checks to see if it is modified.
if it detect a change it did not make, it calls a bugcheck.
in this case the driver could not read some data, most likely because its data was modified, and it bugchecked.
-this can be caused by bad ram. (run memtest86 to test ram)
- this can be caused by file corruption in win32k.sys
(common on pirate versions of windows, and versions hacked by malware)
run cmd.exe as a admin
then run the system file checker
sfc.exe /scannow
this will scan core windows files on the hard drive for corruption and fix them with the backup copy.
(problem is malware often modifies the back up copy)
- this can also be caused by other drivers that rampage thru memory and write over other drivers data.
programming mistakes in drivers. Lots of older versions do this. most often found with USB devices,
and in particular USB wireless devices. to fix you have to update BIOS, install the current CPU chip set drivers for your cpu
and try to find the current USB driver for your device. most of the time people will get a different bugcheck on each boot of the machine in the case of general memory corruption. (because windows loads drivers in different orders on each boot)
if you post the memory.dmp file to a share it can be looked at with a debugger.
if you have problems getting it, copy if from its current location to another location on your drive first. You may have only read writes to the file in the default location.
