Hi, guys. Sorry to annoy you again but I dont know what to do.. After 8 hours of using pc, gpu was fine running at 52 C.. Then I started Skyrim, after ten minutes of playing I was forced to minimize game because of message... When I tried to go back to Skyrim I get Blue Screen Error. I dont know what it was about because it restarted my pc too fast and I was not able to read it.. So I unscrewed all the screws from my case and when I saw gpu there was something weird about it.. So I looked closer and I saw that gpu protrudes from motherboard so I pushed it inside and everything seemed fine to me.. When I was starting pc I accidentaly tapped F2 and advanced mode of bios started.. I saw there was something about cpu so i set it to max perfomance. Later when I started AC4 my fps was around 12, while today it was around 30-40 today on same settings.. After that I set everything same like it was before. I dont know whats the problem but it was pretty much same as yesterday. Sorry for my english. Thanks for help..
