Hello, im relitivly new to PC building. I'll post my specs below. Everything seems to be fine, but I twice now i've had steam installing a few games, and SWTOR installer up and my system will lock up. Only two games updating on steam, not much stress. The tower sounds normal, fans keep going and so on. But my screen locks up and i cant use my keyboard/mouse. Any ideas?
