Hello. I've been using Windows 7 Ultimate for a week, since i've downgraded from 8.1. I have kept the games HDD not formatted, and done just a windows overwrite on the former 8.1.
Today, after minimizing Counter Strike : Global Offensive, i went to watch some videos on YouTube. Suddenly, i heared a buzzing sound in my headphones, and the BSOD appeared, then the pc rebooted normally, and brought me back to desktop.

I used bluescreenview to see what crashed and showed me this.
Bug check string: SYSTEM_SERVICE_EXCEPTION
Driver: win32k.sys
Adress Causing:win32k.sys+c4283
Bug check code:0x0000003b

Any suggestions?

Butbut, i am running w7, as i don't like 8.1...and i've read it may be a service pack problem, done the windows update thingy, but still i control panel, it does not show any "Service pack 1.", whereas in "Updates tab"-service pack 1 installed

Did the sfc test, showed no errors. As the computer is running smoothly for 1 hour , i will plan a chkdsk for the next startup. Hopefully, no more bsods will occur. I have installed updates too. the service pack one, and i have more when i will shutdown.

win32k.sys is the target of malware so you will want to run a malwarebytes scan.

it can also be a bug in your game, Often when a game is minimize it will continue with the assumption that it basically is the only thing running on your system. it assumes that its program is still totally in RAM when in fact portions have been paged out to the pagefile.sys (virtual memory)
It then does a write to memory but its data is no longer there and it overwrites some drivers data structures. Win32k.sys is a prime target for hackers so it actually checks its data for modifications it did not do. If it finds one it calls a bugcheck and stops the system.
if it uses the bad modification, before detection it might also crash because of the bad memory access data

so scan your system for malware, update your game,
run cmd.exe as a admin and check your system files for corruption
sfc.exe /scannow

I may assume it's the game, since i've rebooted my pc, and haven't started it, just browsing, listening to music, the pc ran fine . Now it's 5 hours since i've turned it on, and no problems. I can check the game's cache. will that be good?
The SFC showed no errors.

I would bet it is the game also, when you task switch, windows may swap out parts of the game that is not currently being used. when you switch back windows will load the section into memory again but not necessarily at the same memory address. if the game just continues to access the same memory as before it was swapped out. It could be writing its data over another driver stored data. Then the other driver might fail and get a bugcheck. very common problem with games, often it is why you want to run in full screen mode not a windows mode because of these types of bugs.

oh, I should say this would be common for 32 bit games.
or system with limited pagefile.sys and physical RAM
