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.
Thanks

First of all NEVER update drivers from Device Manager. Video drivers should be obtained from the OEM website, not from Microsoft. Second, does the same thing happen in safe mode? If you haven't tried, please do so.

Thanks for the reply...I have not tried it in safe because it only happens every 5 or 6 times I am on the system. I can try to do this, but it limits my ability to work...I will taske your advise to d/l the update from the OEM...Motherboard or video chip???

So it doesn't happen EVERY time the system is idle for 15 minutes? Then don't worry about safe mode - intermittent issues are very difficult to diagnose.

I did put it in safe mode and...lo and behold...it shut down the monitor...the tower was still running. Also I noticed that the keyboard was not live either...the caps lock and number lock lights did not light up...Does that help? Also, I guess I will have to d/l the chipset drivers???? (there is no card)

If the problem occurs in safe mode it's almost certainly hardware related. Beyond that, the fact that it's intermittent really does make it harder to diagnose.
