I finaly finished my master thesis (after 20 months ) So i decided i'd pay someone to check what was actually going on with my pc. At first he said my motherboard and cpu were broken but after some time he asked an other employee to check the pins on the cpu. They were all bend so problem solved and here im back on et :D.
Thnx for Daredevil and Raziel for setting my lvls.
See you all in the field
