I have a HP Windows7 and I've had it for about 2 years with no problems at all until recently. About a week ago I was using it and left it alone for a few hours and when I returned to my office to use it the screen was black and the number lock, caps, and f12 key were lit up. Now when I try to cut on the computer the screen is black and those same keys are lit! I have to continuously cut it on and off before the computer operates normally but then it freezes once I start using it so I have to cut it off and start the process all over again!! Needless to say I am becoming more frustrated by the day. Can anyone please help me??
