my laptop started to act strangly lately, the cpu was almost always at 100% usage and i could not open any games or heavy programs , i used system image to install windows, but now, games like assasine creed odasy start and work for about 30 to 40 minutes before the game shut down without any message from windows.. while playing cpu reaches100% ,which i don't remmeber happening before the problem started... i decreased the cpu power because my laptop started to heat up without thermal thredling at 3.5 GHz before the problem started..
