Okay so i installed the latest drivers for my card (Crimson 188.8.131.52) And i was suffering from pc crashes everytime i play games. I was playing the crew for around 20 minutes the card was at 70c (locked) and the fans on my pc were going on max speed (dunno why) And my pc was just rebooting.
If you get this problem like i did. Just uninstall that driver. and install the oldest one (the first one available in the downloading page)
I'm opening this thread to warn people so if they have this problem they might know what todo
