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! :-)

    Windows 7. Amazing build. Nothing else wrong but I have the same issue, can't put my computer to sleep b/c the display will never come back on. The computer comes back but not the display. I hope Microsoft comes up with a fix for this soon so I don't have to always shut my computer off. Great OS but this issue is flat annoying.

    Folks, after trying everything with this, here is what worked for me, and it is really simple.  Let's suppose you have your monitor set to turn off after 15 minutes.  Well all I had to do was go into power settings and also set the computer to sleep at 15 minutes.  Because ironically, if the computer is in sleep mode it *will* come out of it and in the process will also wake the monitor!  NOTHING else would fix the issue for me.
