I own an ASUS D1 series portable computer. Just recently the LCD screen suddenly turns off and no hard disk activity is present as if my unit freezes. The power is still on though and the processor fan still running. It's not because of the power settings... I already checked that. When I reset the unit everything becomes fine but after certain minutes my unit freezes again, LCD turns blank, and my unit becomes unresponsive. I've tried reseting multiple times but after 3, 4, 6 minutes it happens again. It's also not a virus. Can someone help me with this?
