BSOD 3b after graphical experience, please help

[dendrees]

After playing a game or other graphical experience I get this BSOD:

SYSTEM_SERVICE_EXCEPTION (bluescreen view)
0x0000003b
00000000`c0000005
fffff960`002ac9ed
fffff880`0915c110
00000000`00000000
Caused by driver win32k.sys
Crash adress: ntoskrnl.exe+68d80

In windows it's stable, only after a graphical work.
I did a clean install of Windows 7, updates the Nvidia drivers (latest version). Shutdown antivirus. Removed the Intel RST drivers. But it still happens randomly. I think it's a driver issue with the latest Nvidia driver.
I removed the drivers with drivesweeper in safe mode and installed the latest WHQL drivers. But when I open Geforce Experience it's always crashes.

Did a driver stress test with Driver verifier. When I booted in windows instantly a BSOD.
Caused by AsUpIO.SYS

DRIVER_VERIFIER_DETECTED_VIOLATION
0x000000c4
00000000`000000f6

This is a hard one.
