Basically it could be at any time. For instance, once i was just downloading a game and it froze, another time I was changing a song on spotify and it froze.

The shut-downs occured once whilst playing BF3 multiplayer and just randomly browsing the Internet. Ive changed thermal paste and the cpu fan is facing toward the ceiling of the case. Temperatures seem okay ( using HWmonitor) Please help me :/ I do not have a clue what is wrong
