Monitor Going In/out Of Powersave Mode Only During Windows 7 Startup
Aug 8, 2012
This problem only occurs during W7 startup, after the "Starting Windows" logo screen. My display then goes black. A few seconds later the status light on the monitor changes color and it displays "Entering Power Save Mode". Several seconds after that, the display wakes up, showing me the user login screen. Then, all is well until next startup.
My PC is a new build:
Intel i5 2500K CPU, has onboard GPU (unused)
Mobo is ASRock Z77 Extreme4
GPU is a GeForce GTX 560
(known good) Dell monitor, ST2220
I've tried different monitors and tried switching to the other DVI connector on the GPU, no joy. Removed & reseated the GPU, no luck. Don't see any BIOS or Windows settings that seem to apply here. should I go ahead and call EVGA support for my GPU? Reaching the end of my rope, as I can't seem to find anyone else with this particular problem on the Inter-Webs.

I have dual monitors that work perfectly at windows startup.After leaving the computer alone for sometime (after powersave has occured on the monitors), I arrive back to the pc to find only one monitor returns from powersave (the same monitor everytime) Rebooting the system corrects the problem; or entering the device manager and selecting "scan for hardware changes" will also correct the problem.I've updated the video card to the most current drivers possible and do not know where to go after that. It's very annoying and have the exact same thing happening with a PC at work with completely different hardware.

Win7's LCD power save mode, after a few minutes, gets constantly disrupted by an application. As this happens with detached mouse and keyboard, I think a process might be the culprit. But how can I know, analyse which one? Are there "usual suspects"? Is there a system log entry for that?

I have a Windows 7 installation that I seem to be in an 'endless loop' on. First off, if I just let the system reboot, it comes to the windows 7 splash screen and then reboots again. This will happen endlessly if I let it.If I hit F8 during boot up, I do get the Windows 7 menu. I have tried using the 'repair' options, but they don't succeed in solving the problem. I have tried going into Safe Mode and that also reboots after getting to the 'CLASSPNP.sys' driver (at least that's what it displays on the screen).
So I thought I would just 're-install' Win 7. I boot from my Win 7 DVD, and my options are 'upgrade' or 'clean install'. If I do 'upgrade', the DVD tells me that I need to start Windows first and then run Upgrade. Of course, I CANNOT do that since Windows 7 won't start! I'm afraid to do CLEAN INSTALL as I don't want to lose all the files

I can only run Windows 7 Home Premium (different computer than the one I'm posting from) in safe mode. When I try to use the Diagnostic Tool, it says that it is saving the files but then it doesn't finish up with giving me the folder on my desktop. How I can get the files to show so that I can attach them to this thread?

I've recently upgraded my computer with an ASUS P6P67 Pro, Intel i5 2500K, Corsair Vengeance 8GB and Corsair TX650 The operating system is Windows 7 Ultimate 64-bit.The installation of hardware went fine, I used my WD Raptor 64GB as system drive and connected my 2 other drives.Maxtor 250GB and Samsung Spinpoint 750GB. (they will be replaced eventually)The installation of Windows 7 also went fine, no problems at all. When it was installed I could see all harddrives and I could browse them. But after I installed the drivers from the DVD from Asus and restarted the computer it hangs at the Windows logo waving. It just keeps waving for hours.When I disconnect the Maxtor and Samsung drive, it boot up correctly. I've only tried to connect them to the Intel SATA Controller. I tried to switch between the connectors but it didn't boot up.When the drives where disconnected I could resume the configuration of Win 7 and I ran Windows Update to install SP1 but still the same problem when i tried too connect the drives?I reinstalled 2-3 more times, but no. Then I changed in BIOS from ACHI to IDE on the Intel SATA Controller and reinstalled again and now it works?I updated everything in Windows and restarted it several times and it boot up every time. But I wish to use ACHI, since I'm planning to run RAID 0 I've used the latest chipset drivers from Intel and IRST as well.I need to clarify that the problem begins after the installation of chipset drivers.

I've got Windows 7 Ultimate (x64), my graphics card is an ATi 4670HD and my widescreen monitor is a 22inch Samsung SyncMaster 225MW.
Everything looks and works perfect. When I go to display, I click detect, and ofcourse it finds my monitor and sets it to its native resolutiob (1680*1050.)
But when I restart my computer, it will be set back to 1024*768 and it will be listed as the generic monitor.
The latest ATi drivers are installed on a fresh copy of Windows 7 and there were no hitches at all. Also to add, I've got 2 seperate DVI cables used to make sure the cable wasn't at fault and they both give me the same result.
What is the problem? This is one I can't quite get my head around.

Earlier today I tripped over a headphone cord and it flung my computer off my desk. I have an HP omni PC. It's the kind that had the computer and the monitor built together. I picked it back up off the floor. The power cord came out on impact. I set everything back up and was relived to hear it turn on. I selected start windows normally (win 7 64 bit) and it sat at starting windows forever. I eventually manually shutdown the computer. I powered back on and I got an option to start windows normally or use startup repair.
I thought it would be a good idea to go into startup repair. It just sat at the light blue screen with the large white mouse sitting there. Nothing happened. Nothing appeared on screen. I turned off the computer again and am just leaving it there for now. I am worried that the hard drive may have been disconnected from the fall and that's why windows won't start. Or maybe the hard drive was damaged. I tried doing a safe mode boot but it redirected me to startup repair.

when I made a boot defragmentation of C:/, after 5 minutes my monitor showed up "no video imput" and got in stand-by. This was frustating: I had to wait until the system started to beep, and reboot... And second, I wanted to find some settings in the BIOS to fix this problem, I started to search, and after 3 or 4 minutes... the same thing: "no video imput", and a black screen... How can I get my monitor to work in vga mode also? Or is something else here? Some infos: I have a HP XW-4400 Workstation, it comes with pre-installed XP, but for two years I upgrade it to Windows 7 Pro. I installed all the drivers for Windows 7 from the HP site, because on my recovery CD are only the drivers for XP. Some of the Windows 7 drivers failed to install... but all that I could install, I installed. I tried to find a driver for the "on-board vga intel video driver", but nothing to find on the HP site... I already searched everywhere on the Windows 7, and I put all the settings for monitor and video to sleep "never", but with no change when it comes to boot operations. It is very risky to not see what is going on when you defragment on boot, or when you are in the BIOS settings...

I recently got a virus 2 days ago. It disable my possibilities from accessing any program or internet. I made a mistake by downloading a windows something ware to boot up security. It then crash...so I went to task manager didnt work, which i then went to search and entered msconfig. I then chose safe mode in minimal services. It then says loading files. U see a black screen with thite letters of the files being loaded. Then u see ur mouse cursor, and then it boots up again and same process. So I tried launch startup repair, it launches a repair, but it says it startup cannot repair this computer automactically. I then result into going to tapping f8..it goes to the screen of advanced options. Problem is if i try safe mode it will crash. I dont have a backup, and i dont want to lose my movies of over 700 gigs.

im having problems with my monitor, it doesnt want to get out of sleep mode. Right now I have the comp apart which is no problem for me to put it back together. Im assuming its either the battery not giving enough power or the connection where you plug the monitor into is bad.

I have a Dell Studio XPS435 MT running Windows 7. For the past six months I noticed that when waking the computer from sleep mode, occasionally the monitor would not wake up and I would have to reboot. It got worse and worse until now it will never wake up without rebooting. I also noticed when I reboot, if I don't wait a few seconds for the computer noises to stop and immediately press the power button; the computer starts beeping loudly and nothing works. I have to manually shut it down and wait about 30-40 seconds to reboot.

My computer monitor won't wake up from sleep mode. The power light flashed blue like it is asleep but when I hit the keyboard or click the mouse nothing happens. I even restarted the computer and tested to see if the wires were bed or loose and that didn't help either. I switched out the monitor and the new one works on the computer so it seems it is something with the monitor.

The thread title about sums it up! When I try to wake my computer from sleep mode, my monitor gets no signal/is black. The "rest" of the computer seems to wake up just fine.
The monitor was working fine with Windows Server 2008, after sleep mode, but I just recently upgraded to windows 7.
I have already tried: displayswitch /extend displayswitch /internal in a .bat file
using "Hibernate Trigger", "Power Triggers" and Windows task sheduler.
Doesn't work at all for me (I've got Windows 7 Proffesional 32-bit Service Pack 1)

Is there a way to force Windows to use the default monitor settings as used in Safe Mode, but when running in normal mode? My Nvidia GE 6100 graphics began scrambling the screen. Safe mode works ok, but on normal startup, the screen is scrambled or goes fuzzy and everything freezes. I think it's a hardware problem (it started after I added memory) but I want to keep running until it can be fixed. I have updated the drivers but it did not change anything. I tried deleting the Nvidia driver, but Windows keeps finding more.

I left my computer running overnight as I usually do. When I went back to it this morning, it was stuck in power saving mode. When I rebooted, everything looked fine and the windows logo loaded but when I reached the login screen it went directly to Power Saving mode and got stuck there.
I am posting this from Safe Mode with Networking.

so the Windows 7 Ultimate 64bit install is fresh, and all the drivers are the latest available. I have updated my mobo's bios to the latest version through Asus' "AI Suite II" which makes things very simple. I want my PC to be able to go into sleep mode but I don't want to have to force shutdown every time it goes into sleep mode after a time span. For some reason if I wake my PC after its been in sleep mode for a short period everything turns back on just fine... I know there might be a solution through the configuration panel

Annoying intemittent fault whereby the monitor is incorrectly detected as a generic model instead of an LG L192WS and the screen resolution changes to a lower setting which loses a large percentage of the desktop. I've updated to the latest AMD drivers as that seemed to work for others with a similar problem but to no avail. it takes 5 mouse clicks to open desktop and reset the display to the correct one, but after spending quite a bit to speed up my system I begrudge the time!

While my pc is on, I plug in the usb cable of my canon pixma MP276 printer. When the usb cable contact to the usb port, the lcd monitor goes into power saving mode/sleep mode (black) immediately and never turns on again no matter what I do (clicking on mouse, pressing keys on keyboard)I then need to restart the pc and everything will be normal.

Windows Live Messenger needs to run in compatibility mode in order to minimize to the system tray instead of the taskbar. This seems to work except sometimes on startup it does not run in compatibility mode. I have to exit and then restart WLM and then it's ok.

When I'm using the computer...at very random times, the screen goes black, then a blue window pops up telling me it has gone into power safe mode. I'm assuming, when this happens the computer freezes because, when I hit the hot key I set up on my keyboard to shut down, nothing happens...So, the only option I have is unplugging or holding the power button until the machine shuts off. Then, I restart.When I try my hotkey for shut down during normal usage, it works just fine, but not when the monitor decides to take a coffee break and leave me hanging.If I was doing something lame, like work, it wouldn't be so bad, but right in the middle of online gaming??? COME ON!To sneak another question in...which might, very well, be linked to the issue above, the computer freezes at random times as well. Especially, at startup. I have to hold the power button 3 or 4 times...with beep beep beeps...until it finally decides to show for work and do what its job description states.

The monitor seems to go into power saving mode when entering/exiting a game such as a game in steam. (But it doesn't happen every time) the only way to get it out is hard restart. Yes I've tried other monitors, as well as display drivers, and there also seems to be nothing wrong in the Bios.

I'm having some trouble starting Windows. First I was having trouble with booting into safe mode so I done some Googling and I found this page and tried it [URL] now not only can I not start my PC in safemode but not in normal mode either, with checking the option for safe mode in msconfig it now keeps trying to start my PC in safe mode over and over again. I also cannot start my PC with the last known configuration.
I tried repair my PC with my DVD but that cannot fix it. There is no system restore point or recovery saved.
