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.

    I have a Dell XPS410, and have had the same issue for some time. Have changed the graphics card a few times, thinling it was the problem, re-instaled Win7 also. I may have stumbled across a solution. When the problem occured, my power settings were set so the "select what the power button does" was set to sleep, along with power management being set to put the computer to sleep in whatever minutes. I changed the power button selection to make the computer go into hibernation when pushed. Changed to default for each user on the start menu to log off, and still have the power setting set to put the computer to sleep after 60 minutes, never turn off monitor. Have not had a problem with the monitor not waking up in over a month.

     May be dumb luck... but i'll take it.
