MY computer keeps on shutdown by it self
My computer for some reason is shutting down by its self. I don't know why, I tried to scan for virus nothing big comes up, McAfee found no Virus and this problem has still countinued. Sometimes I have lost few really important documents that I might have been typing, and the computer will shut off by its self and won't start for long time. The light in the CPU will stay on but nothing on the screen matter of fact the screen light just stays yellow I believe there isn't any output coming from the CPU, how can I solve this problem and what might have caused it so that I can avoid it the next time PLEASE HELP!! ASAP!! and I'm using HP computer.
THANK YOU
