I don't know where to ask this, so I ask here. I have my system go into stand by mode after 2 hours of inactivity. It has never been a problem until recently. Actually the monitor is supposed to shut down after 15 minutes and then after 2 hours whole system stand by. This is fine until I wake it up by hitting space bar. The system starts up and all but no monitor. It stays asleep. Maybe this is a video card issue? Any ideas?
