Hello guys. 1 mounth ago my computer started acting really strange. When playing some games or just browsing the internet my monitor, keyboard and mouse would freeze. More exactly the light on the mouse would remain open even i would not touch it and the keyboard lights for num lock/ caps lock wont response to the buttons. There was no way to restart the pc so i just needed to press the power button for 10 or so seconds.
The big problem is that i reinstalled my windows 7 several times, and nothing change. Its not constant. It could past 2 weeks not having any problem and some random day it would be impossible to even open my computer. Any idea or advice would be much appreciated.
