Monitor won't wake up when coming back from sleep (Windows 7)

I recently upgraded my Dell Dimension desktop to Windows 7. In order to do so, I had to install a new grapchis card (NVIDIA GeForce).

I set the PC to sleep after a period of time. When I go to move the mouse and wake the computer back up, the PC itself seems to respond, but the monitor never comes back from sleep. I have no choice but to reboot to get the monitor back.

Any suggestions?

A Universal fix would be ideal but - ASUS appears in 14 out of the 16 pages in this thread!!! Not saying everybody having this problem has an ASUS motherboard but if they do, and it seems a high percentage of people do, then they need todisable the PLL Overvoltage in their BIOS!!

IT ACTUALLY WORKS! Not just a workaround, my Computer AND Monitor now both wake from sleep by simply moving the mouse!

Also, obviously only people who have this problem are going to come here. If this is a wide-spread Windows 7 problem, then what about all the complaints large companies like HP Compaq and DELL etc would receive when their customers have the same problem? If they received many complaints and being that  they have a much bigger voice than us they would simply demand Microsoft fix it. I also have a TOSHIBA laptop running windows 7 and it sleeps and wakes just fine.

So if anybody who has friends or family who own a 2011 Dell, Acer or HP etc that came out brand new, factory loaded with Windows 7  please ask them if they have this issue or not. (These companies may have had this problem initially but I would imagine it would be fixed by now??!!)

A lot of people who have this problem also seem to have a separate Video Card (I have a Sapphire Radeon HD 6870 which of course the monitor is connected to) Do any people who are using integrated graphics also have this problem such as people with an H67 mobo?

I am curious as to what percentage of Windows 7 users have this problem. We may find we are in the 1% bracket and 99% of Windows 7 users don't have this problem. It may just be incompatibility of Windows 7  with either our hardware or settings.

In my case disabling PLL Overvoltage works! :-)

    Hi, Guys.  I have the same problem I have a Dell Optiplex 960 (with Intel Core 2 duo vPro inside and n Series) and a dell E177FP monitor with an integrated VGA card Intel(R) Q45/Q43 Express chipset. These computer came without operating system and we installed Win 7 for the student's computer lab.   Surprisingly the system wakes up but monitor does not wake up.  Since I have the luxury of different model of CPUs and Monitors I made an intensive test. First thing that came in my mind that the monitor is not compatible.

    1. The dell E177FP monitor is connected to Dell Optiplex 960 running win 7. Once, twice the monitor is waking up but When left for 4 or 5 hour and also over night it does not wake up.  I have to unplug the power cord wait for some time for the power to go off then plug it in, then you will see the desktop.
    2. I configured another System of the same model to Vista (utility disk has xp and vista drivers) It work perfect it was on for 3 days wakes up as you move the mouse or touch the keyboard.
    3. I connected the monitor Dell E177FP to an HP Compaq dc 5850 with ATI Radion HD3470 card, It work perfect, it was on for 3 days.
    4. I connected another Dell E177FP monitor to a DeLL 520 with XP Pro 64 bit and Dell 745 with XP Pro, it was perfect it was on for 2 days no problem wakes up by touching the keyboard and moving the mouse.   
    5. I connected another model of Dell E177FPb monitor to a Dell Optiplex 960 running win 7. It work perfect, it was on for several days.

    6.  I even intalled a win server 2008 on the Dell Optiplex 960 with the same Dell E177FP it work perfect, wakes up any time with the mouse and keyboard.

    The monitor does not have issues with the any operating system nor the Dell optiplex 960 (win 7) with a different model of monitor.  The problem lies only if is connected to Dell 960 running win 7 with VGA driver installed as Intel(R) Q45/Q43 Express chipset.  I can not prolong the length of time for the system to be on for 6 hours which defeats power saving option.

    It is really weird don't you think so?

    Pardon me for bring so cynical , but after 7 months of posts re this issue I would think a MS Support Engineer could come up with something better than to edit the Power settings, or at least not post at all. That answer might have been appropriate back in January.

    I am willing to bet that Russ has changed those settings so many times he could do it blindfolded with both hands tied behind his back.

    Here is what we know:

    1. It is sometimes intermittent, sometimes not.
    2. It does it with XP, Vista, & W7. It is probably most noticed on W7 because it is more apparent/useful/noticed/whatever and fewer people even tried standby with XP.
    3. It does it with MANY different H/W configurations.
    4. It has been VERIFIED to be caused by memory errors. I personally solved mine by replacing memory. The issue is there may be something else in the system that causes an error in memory when going into or out of sleep that is not associated with actual defective memory. Lack of a UPS on the computer and bad power from the utility is one "something else".
    5. What is needed from "support engineers", who KNOW the hardware and software of these systems, are ideas on things to check/test/change that might lead to a solution.

    I am an engineer. I realize that without touching/seeing the system anything is a guess. I repair computers. I am, however, not intimate with the hardware/firmware/software as I once was. Back then I solved difficult issues in Europe from my desk in the US.

    There are people with this kind of visibility. Apparently, they don't read these forums.

    Hi Russ,

    Thank you for your post.

    I suggest editing the Power Options > Advanced Settings to see if it may resolve the issue.

    Just another 2p from me, my faulty machine has an ATI Radeon X800 I think, old AGP model.

    Also sometimes if I RDP into the machine I can wake the monitor up, no idea how this works, but I have RDPd in from my laptop.

    I've just realised my laptop (win7) also does it, if I close the laptop (so screen is off), then plug the power supply into it, then open screen, I have the exact same dead screen problem. Only way to solve it is power cycle :(
