"Page fault in nonpaged area" appears at startup

From time to time when i put on my pc, i get the error page fault in nonpaged area, and this code:
STOP: 0X00000050 (0XF7576712, 0 X00000000, 0X F755D051,0X00000000)
When i then want to try to start in safe mode, coming in the logon screen with the different users, the pc crashes and restart again, and most of the time then it goes well. But now it didn't, i tried a couple of times, and when everyting seemed ok, i had to reactivate my version of Windows again using my phone.
Thes troubles came after downloading a patch for the game DTM Race Driver 2. I don't dare to uninstall and re-install this game again, because i had trouble installing it when i got it because of SP 2. Is there a possibility to just remove the patch?

 

That would be a better question for the game's tech support folks.

 

that game uses starforce copy protection. Google it for yourself to see what most of the community thinks about it. Lots of reports of it causing huge problems for a lot of folks.
