random restarts --> "Problem Event Name: BlueScreen Locale ID: 1038"

Hello,

The problem seemed to escalate yesterday just before I wanted to start the "perform a clean startup - reduce items on start" method.

Interestingly the system did not restart, neither crashed, but it was continously "laggy", the mouse cursor moved hardly, and also its shape and color changed.

So just as try, I removed the newest Nvidia driver (320.49), and I did a restart. Win7 automatically installed on the fly an older Nvidia driver (311.06 version). Since this, my PC did not crash again, and it looks ok.

So I really hope this was the real source of the problem, if not, I will do the above mentioned method (what looks quite a big effort).

Thanks for advices! If I do not get BSOD in the next days, I will mark this post as solved.
Regards,
