I have a 1 year old Gateway desktop running Windows 7 home premium with 4gb ram. Sometimes, when I am working and the system may be idle for 15 min or so, the monitor will go into sleep mode. It shows no signal, and no keyboard action will awaken it. I have the power settings to never turn off and the screen saver is off as well. I swapped out the monitor with another and it did the same thing, so I think I have eliminated hardware. I then went to the device mgr and attempted a driver update, which said I had the latest driver. The only way it will come back on is to cold boot the system. BTW, I hace reseated the video cable as well.
