Hi I'm new here and know absolutely nothing about computers. 2 days ago my computer wouldn't come on after I had shut it down. The light comes on and the cd/dvd drives will open and close. But, the monitor says it is in power save mode and the mouse and keyboard do nothing to get it out of power save mode. A friend of mine told me to hit the f8 key a couple times and this worked. It got me back up and running as if nothing was wrong. I did a virus scan and no viruses were found. Everything ran smoothly until I tried to turn it on last night. Exact same problem only this time the f8 key does nothing. Does anyone know what the problem is?
