My computer was in sleep mode, and i couldnt get it out. I tried CTL+ALT+DEL, I unplugged the mouse and plugged it back in. I couldnt do anything to get it out of sleep mode. I had to turn the power off to my computer without shutting it down (I know this isnt good for the computer) in order to get it to restart. When i turned the power back on to my computer a black screen came up, and said Windows will restart in 20 Sec... or i could choose to "Start Windows to last setting that worked" "Start Windows in Safe Mode" "Start Windows in Networking Mode" and there was one other option that i cant remember. I chose each of them and the same thing happened with all. It would act like it was going to start windows, but then it would just take me back to this black screen with the same options. Also, When it would act like windows would start up, there is that blue screen where you can hit f10 for recovery, or f1 for setup or escape. I tried to hit f10, and it would just turn into a blue screen and freeze. I hit f1 but there wasnt anything there that looked like it would help.
