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! :-)

    There is so much written about this not only in this topic. I, like others have changed video card, monitor etc. I use the only work-around that will always work - no sleep on the monitor and no sleep for the computer. I never really tried the other option of never hiding the taskbar.

    In my case, the problem only happened when I upgraded to Win 7. When I has Vista with the same hardware then, this problem never occured.

    The bottom line - there are many work-arounds but no solution as yet. Even MS put out a patial patch and also a hotfix. I have not tried the hotfix. I will wait for SP1.

    Spokus:

    This indicates that the monitor is a problem, possibly in combination with your video card. This is very likely a hardware problem.

    One further question: Does the display appear in the resolution changer panel?

    If not, than something like the five volt line from the graphics card which feeds the identification logic in the monitor might not work in your current setup when the monitor is asleep. This is not obvious during the boot phase, since the bios sends the signal without regard to the monitor.

    Seymour:

    Uhh, doesn't the fact that it works in some cases indicate that there are different causes?

    And doesn't that indicate that a one size fits all solutions is not likely to be possible?

    All the anove 'proposed' solutions are not solutions. They work in some cases only.

    To me , a solution is one that works in all cases and is not just a work-around.
