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 have scored these  boards and others and done everything  can and still my computer does not wake up using windows 7.

    The only way I can wake it up is to actually switch the power supply off at the back and then press the power button, often 2 or 3 times, until the computer reboots - often telling me that it was not shut down properly.

    This IS a Windows 7 issue!

    I have now had it on 3 computers now that I have installed win 7, one as an upgrade on my old desktop, one a laptop as a new install and on this one I am using now on a completely new desktop I just built.

    My old desktop was a little easier to wake up as if I kept pressing the power button several times and if it did not work  and ctl alt del a few times it would wake up, the laptop I had to switch off completely and this new one I have to pull the power, put it back again and then reboot.

    I see no point in listing the hardware etc on any of these machines as all have completely different hardware and all while running Win7 have the same problem.

    On two of them I gave up  I have wiped and reinstalled with a previous operating system and they are BOTH totally fine now. The laptop I re-installed to vista and the desktop as my daughter wanted it to play older games I put Windows XP on it and neither now have this wake up problem!!

    But my own newly built desktop that I need for work which I have left running Win 7 still does not wake up!! This despite updating every driver ( did that on the other two too before I gave up and reverted back to older OS on both of them!)  trying every workaround I've read on theses forums and many others - including switching off hybrid sleep as suggested by many and on many forums - this made it worse as now it requires a reboot at least with this on it seemed to hibernate and woke up finally looking as it had when it went to sleep with the applications and windows I was using still on, but only after I had turned the power on and off and pressed the power button several times.

    When is the Windows tech team going to accept that this is a windows 7 issue, a BUG that they need to fix and issue an update to fix??

    I may not be a tester anymore but I was a beta tester for win98, WinXP and ME and I recognise a bug when I find one

    Please get it fixed Windows!

    Thank you

    I fixed my wakeup problem today by turning on the feature "require password on wakeup". I'm the only user at home and I don't use a password so I had turned this feature off. Not sure why this fixed it. The symptom was that on wakeup all screens were blank but I saw the mouse on the secondary screen. Ctrl-Alt-Del and going to the Task Manager would force the screens to wakeup but on occassion it would result in a BSOD (blue screen of death).

    There are many issues that cause wakeup problems. Tried updating to the newest drivers, tweaking and testing the RAM, hotfix KB977178 then clean installed windows 8 times with hundreds of sleep mode tests. After two weeks I finally narrowed is down to the "require password on wakeup". I sure this is not the issue with everyone here but let me know if this helped in your problem.

    My desktop setup is ... Windows 7 Pro 64 bit, ASUS P5Qse Plus motherboard, Intel Q8200 cpu, 250GB Seagate 7200rpm boot drive, WD Green 1.5TB storage drive, G. Skill PI 6400 4GB RAM and 3 video cards in the Radeon x1300-1500 series

    I have the same problem I believe it is a thing with win7 i had my system on vista before and didnt have that problem. myself the only way i can get it to restart is shutting it off unplugging it for 2 min then restarting it. the only way it comes back up is if i have a game or a program running in the back like windows media player.

    On my PC I hit CTRl-ALT-DEl a few times and then select Task Manager and that wakes up all my monitors. But this is not a fix for the issue. Someone had sucess in fixing this by rolling back the driver for the video card.
