Hi all, this only happens on rare occations but none the less, it still happens.

Basically when I connect things such as USB devices, e.g MP3 players, controllers, headphones, my screen goes black with the usual "no signal" message. The only thing I can do to get the PC back to life is to restart the system.

When it cuts out, there is stil power going through the system, because the LED lights and fans are still active.

As I said before, this happens on rare occations, like once every few weeks. Im thinking its the motherboard or power supply, although the system never cuts out when under stress, which leaves me to believe it isnt the power supply.

Could you guys shed some light on this ?

Thanks in advance.
