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! :-)

    This is very frustrating.  Once my computer goes to sleep the monitor will not wake up.   I installed window 7 about a year ago and installed a Gforce card about 5 months ago.  Everything was fine, but recently my computer was slowing down due to junk in the system.  So, I did a clean re-install of windows 7 and now the monitor won't wake up.  Sleep mode is awesome, because it requires no time to boot up.  I can't believe Microsoft hasn't found a fix for this issue!

    I am SO SICK of my monitor not waking up.  This is a WINDOWS 7 PROBLEM.  I now have BOTH monitors on HDMI cables (one is on DVI to HDMI now, which used to be VGA), and the problem persists.  My computer is not set to go to sleep, so it's always on.  Only the monitors are set to turn off.  This problem manifests itself only if the monitors are off for a long period of time, like overnight.  When I come to work in the morning, my primary monitor does not wake up when I click and move the mouse, even though the secondary monitor does.  The only way to wake it up is to remove the HDMI connection on the active monitor, which seems to force the system to activate the other monitor that wouldn't wake up otherwise.  I think this is a SIMPLE problem, where the OS cannot get it straight which is a primary monitor.  It needs to wake ALL MONITORS SIMULTANEOUSLY, ALL THE TIME.  I think they're doing something like trying to wake only the primary monitor until the user logs in, but it's guessing the wrong monitor is primary and waking up the wrong one.  JUST WAKE THEM ALL.  If I don't see a patch to fix this in the next month, I'm just going to start pirating everything, because there's no way I'm going to pay for broken $hit.

    The time and money I've spent effing with this thing every morning (posting here, trying to log in blindly, pulling monitor cables out every day, purchasing HDMI cable and DVI to HDMI converters, etc.) outweighs the cost of the software.

    I have been having intermittent failure to come out of sleep mode too.  This started a few weeks ago.  The settings are all OK as per the 3rd post here about allowing devices to wake up the system.  After about 6 minutes the PC automatically reboots.  I am unable to find how to set the Balanced power setting to Active.  So I just have Power Saver [Active] and each setting at 2 hours.  Maybe this will help but have not had enough time to evaluate.

    I started getting identical symptoms a few days ago (monitor would not wake from sleep). In my case, the solution turned out to be trivial (once found).

    Over time, the cables to my monitor had slipped downwards slightly in their sockets. To my surprise, reseating them cured the problem.

    You may want to try this before exploring more exotic solutions.
