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! :-)

    I fixed my wakeup problem today by turning on the feature "require password on wakeup". I'm the only user at home and I don't use a password so I had turned this feature off. Not sure why this fixed it. The symptom was that on wakeup all screens were blank but I saw the mouse on the secondary screen. Ctrl-Alt-Del and going to the Task Manager would force the screens to wakeup but on occassion it would result in a BSOD (blue screen of death).

    There are many issues that cause wakeup problems. Tried updating to the newest drivers, tweaking and testing the RAM, hotfix KB977178 then clean installed windows 8 times with hundreds of sleep mode tests. After two weeks I finally narrowed is down to the "require password on wakeup". I sure this is not the issue with everyone here but let me know if this helped in your problem.

    My desktop setup is ... Windows 7 Pro 64 bit, ASUS P5Qse Plus motherboard, Intel Q8200 cpu, 250GB Seagate 7200rpm boot drive, WD Green 1.5TB storage drive, G. Skill PI 6400 4GB RAM and 3 video cards in the Radeon x1300-1500 series

    I have the same problem I believe it is a thing with win7 i had my system on vista before and didnt have that problem. myself the only way i can get it to restart is shutting it off unplugging it for 2 min then restarting it. the only way it comes back up is if i have a game or a program running in the back like windows media player.

    On my PC I hit CTRl-ALT-DEl a few times and then select Task Manager and that wakes up all my monitors. But this is not a fix for the issue. Someone had sucess in fixing this by rolling back the driver for the video card.

    Suddenly,  the wake up monitor problem disappears.

    I said that all my drivers are up to date.

    But in reality new version of NVIDIA driver appeared 6 day ago. I did not know about it.

    I have installed this "brand new" driver and my monitor began to wake up properly.

    Hope, somebody help this information.
