This has been happening randomly for 2-3 months now. I'll be using my computer and all of a sudden the LCD goes blank and turns off as if in power saving mode. I'm not playing games on it. Just typical windows/internet stuff. If I put my system into sleep mode, and then wake it up everything appears fine. Also, if I reboot it everything appears fine. However, sometimes it will do this several times in a row...or sometimes not for days. I can't find any rhythm or reason for it. My system is not over heating at all. All temps are fine. I don't think it's an LCD problem...I'm thinking maybe a video card problem but I'm not sure. I checked inside the system and all of the fans are running.
Any ideas?
