Hi, ive just built a new system and it has been running fine for about a week and just yesterday it crapps out. I was playing counterstrike when the screen blinks for a sec and then the whole computer just shuts down. When i go to turn it back on, the fans spin the hd spins but the system led never goes on and the hd led is at a constant on. The power button then wont work to turn it off and i have to unplug it. This is very strange and this exact same problem has happened to me before. Any ideas on what i can fix or how this happened? thanks! Specs of system are in my sig
