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 had tried updating my drivers before with no sucess however i checked the ASUS website (my graphics card is a ASUS 7600 GT) and in the last month they had brought the first driver for it that specified win7 so i tried it and yet again the problem persists. the next thing i will try is see if there is a more up to date monitor driver as the problem seems to be monitor specific as 1 of my monitors is always affected and the other isnt regardless of setup. i have yet to test the memory proiperly however i doubt it is the problem as the isue has persisted from before and continues after a memory upgrade.

    SO, what u are saying is that u have one machine with a newer driver installed by M$ during the OS install that sleeps and wakes just fine, but u had to install an older driver from HP on the ghosted machines to make them work?????????????????????

    I just can't put my mind around that one as a solution.

    I've found the solution and hope this will help all of you who experience the same problem.

    I installed Windows 7 (64 bit) on a HP Compaq 8000 SFF PC and it didn't have any problem waking up by a keyboard or a mouse. However, I created the image from this computer and ghosted it to 28 lab computers (they are all HP Compaq 8000 SFF PC) and then the problem happened on all of them. After they went to sleep in 10 minutes, none of the computers could be waken up by the keyboard or mouse (the very first HP from which I created the image still didn't have that problem). I tried the BIOS or power options but all the suggestions posted here didn't work, so I decided to reinstall the video driver.

    I went to the HP web site and downloaded the video driver for my HP Compaq 8000 SFF PC. When I installed the driver, Windows 7 asked if I would like to overwrite the existing driver because it was newer than the one I was trying to install, and I just decided to overwrite it without a doubt. After the reboot and let the computers slept in 10 minutes, every one of them was able to be waken up by either keyboard or the mouse.

    I'm glad the original video driver from HP has solved this problem before I try to put in the new memory.   =)
