help analyzing minidump..

Hello, I know this is a common problem and I've tried searching for solutions but I haven't been able to solve it. The win32k.sys BSOD is completely random..I didn't get it at all Thursday, I got it 3 times Friday (once while playing a game and two times just surfing the internet), and not at all today. In fact, I didn't start getting this error until last week. If anyone can help me or give me any advice, I would appreciate it a lot. Thanks in advance. I also have a longer debuglog if you'd rather refer to that instead.

-Prime runs flawlessly (all 3 tests) for 20+ hours.
-Memtest86 passes 25 times without errors
-Hard drives are error free

KERNEL_MODE_EXCEPTION_NOT_HANDLED_M (1000008e)
This is a very common bugcheck. Usually the exception address pinpoints
the driver/function that caused the problem. Always note this address
as well as the link date of the driver/image that contains this address.
Some common problems are exception code 0x80000003. This means a hard
coded breakpoint or assertion was hit, but this system was booted
/NODEBUG. This is not supposed to happen as developers should never have
hardcoded breakpoints in retail code, but ...
If this happens, make sure a debugger gets connected, and the
system is booted /DEBUG. This will let us see why this breakpoint is
happening.
Arguments:
Arg1: c0000005, The exception code that was not handled
Arg2: bf82c192, The address that the exception occurred at
Arg3: f4f97ab8, Trap Frame
Arg4: 00000000
