I recently shut down my computer and walked away. When I came it sounded like it was still on because the fans were running. There was a red led light on at the front. I tried to use the computer but it would not respond. I pushed the power button and reset button, neither would do anything. I flipped the master power switch off and it shut down. When I flipped the master switch on again the fans started up, the red LED light came on, a green light turned on at the bottom of the motherboard and a light turned on on my wireless card. There was however no system response or image on the monitor.
Typically if switch on the master switch I still have to press the power button to start the computer. Now, this is not the case.
Any ideas what is wrong with my computer?
