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! :-)

    Well, after googling my problem, when I got to this page and saw that the first post is dated back to Jan 2010 I thought there would be an answer at the last page! I cannot believe they haven't solved this problem after this long time!

    I agree, I have decent tech knowledge and have tried literally everything to get my monitors to wake from sleep. The web is littered with questions regarding this issue and few people manage to resolve it. When thousands of people suffer from the same symptoms one would hope that MS would at least acknowledge the problem.

    MS Windows 7 64-bit Bus

    Intel Core i7 2600K

    16.0GB DDR3

    ASUSTeK Computer INC. P8P67 PRO

    LG Flatron W2442 (1920x1080@60Hz)

    BenQ E2420HD (1920x1080@60Hz)

    NVIDIA GeForce GTX 460

    Has anyone found a solutions - I have two Dell's Opti 330 & 760 that have just been recently updated with Dell drivers and freshly installed with Win 7 Pro 32 - also the full bevy of windows updates plus some driver updates via windows.  Of the 17 machines I had done the same procsses these two have the same characteristics as mentioned:  Monitor goes to sleep mode and will not wake even though the machine is running.  Only option when this occurs is to hard boot the system, and I hate it each time we have to do this.
