When I woke up this morning, I noticed my monitor was just a black screen and the power light was flashing and I couldn't get the screen to come back on (because I leave left the monitor on), even moving the mouse or nothing wouldn't make it come on. I had to reboot my PC to get the screen to come on. I've come the conclusion that it may be: 1. My power options in control panel. 2. New 9.2 ATI drivers. 3. I've overclocked my card to 800MHz on core and 1000 on memory in CCC. In the power options, in the balanced settings, the top option was set to 20 minutes but I set it to never (so screen don't go off, something to do with sleep mode). I haven't left the monitor on for a while yet so see if the problem was the power options. Suggestions? Also, I have one more issue I've noticed. Sometimes when I exit games, my monitor just goes black and I see (slightly) black lines vertical going down the monitor).
