I read your post and I'm just guessing here
"In power save mode press computer power button or any key on keyboard or move mouse
"
it means you need to click ur keyboard / mouse do any action to bring back ur pc to its normal working mode
sometimes you need to press the "turn on" button (on your pc) to stop the power save mode, I dont know.... some pcs work like that .. !!!!
dude,just replace ur keyboard and mouse and c if that works for you
><" otherwise, your graphic card might be corrupted
Good luck
