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! :-)

    The solution to this problem for me is that the problem occurs everytime i have a USB flashdrive or USB external harddrive connected to the computer while it's asleep

    If no usb storage devices are connected when i leave my computer (and the monitor turns off) it wakes up with a 100% positive rate. So something in the wakeup sequence fails because of the usb controller/driver software etc.

    Not a problem solved I guess, but at least i know my computer isn't ill hardware-wise

    Same problem, and I've disabled my screen saver (KB976427), and have an Asus P6T Deluxe MB running Win 7 Ultimate 64 bit, NVIDIA GeForce 9600GT, with a UPS. A few folks seem to find (short-term?) fixes involving their PSU, memory defects, updating drivers . . . but there seems to be thousands of users experiencing this problem, with many different hardware configurations, and thousands of users who have lost much time and hair, seeking a resolution, with no satisfactory solution.

    I cringe at similar threads where the MS Support Engineers or other gurus start another hapless Windows user down a likely dead-end path of updating drivers, changing their Power Options, testing memory, etc. Why can't MS admit that this is an endemic problem, publish an honest KB report and start working on a fix?

    This is the best thread I've found so far on this widespread problem. To help people find this high-quality discussion, I'm herein pasting some of the endless ways in which people have described this problem in their "subject" lines.

    I performed a clean install of Window 7 x64 a few weeks ago and everything was running fine.

    That is until a few days ago. The system went to sleep and no matter what I tried I couldn't get the display to detect a signal from the PC, even during post. This was very frustrating. I went through the usual troubleshooting (cable swap, monitor on different system different monitor on target system, etc). I eventually used a DVI-VGA adapter and was able to get up and running. But obviously that was not a long term solution. I was about to submit and go out and get a new video card, when I came accross this page: http://www.playtool.com/pages/dvitrouble/dvitrouble.html and I tried the solution: turn the monitor on after Windows boots. This got me back up on DVI. Prior to completing this however, I had completely removed the manufacturer driver, in my case NVidia 260.99, and let windows pull down the windows update supplied driver. That was yesterday, and so far, so good. The display comes back up after sleep.

    Both my wife and had been all ready to blame MS and we even discussed getting a Mac, which we will do anyway, when it becomes necessary to replace this system. However, after explaining to her what I had learned and how I solved the problem it became clear that it was not really a Microsoft issue. Don't get me wrong, I have no love for the M$ machine, but I have to be fair. It really seems that the issue, at least in my case was an issue of hardware. My video card manufacturer supplied drivers was unable to correctly process EDID data from my display (BENQ G2410HD) .

    As I say, so far the Microsoft supplied driver has not produced a repeat of the problems. I'll post if that changes.

    I have 3 windows 7 desktops, all have ATI video cards, 2 of them Sleep and wake fine. One does not, I have Sleep shutoff, but when using Sleep I had to hard  power down and restart to get it back. I think my particular Model video card is the problem.

    I have tried the following:

    changeTurn Off Displayto "Never"

    switch OffHybrid Sleep

    then enableSleep

    Bios is set to S3
