    Well that did not work :( I have found out that it is a driver problem but i can't find the root of the problem :/ I have tried downloading older drivers but the problem is still there i wonder if it is the GeForce experience there is the problem.

    I have the same problem but I am using another gpu (Nvidia Geforce GTX 675M) I did not have this problem until my windows 8.1 updated about 2 weeks ago (november 2014) 

    If you find a way to solve this please reply.

    Regards Jonathan
