Every so often when i go on my computer after i type in my password and log on my moniter says power saving mode for about 10 seconds before actually switching into my account. Usually its not a bad problem but now after it goes through power saving mode my screensaver comes up and then it boots me out of my account and i have re enter my password and hope it doesn't mess up again, usually it only happens once bt one time it happened 4 times in a row so it took me 5min to get on my computer.
