Win 7 Freezes When Monitor Powers Back On
Jan 24, 2010
I don't know what this could be, I set my system to power off the monitor instead of using a screen saver. When ever I try to power it back on the screen will come on with the desktop as I left it, but the computer freezes.
So I reboot and during the reboot it checks my C drive for consistency, never finds a problem. Other than that the system works fine, and it doesn't happen every time, more like once or twice a week. It happened twice today which got me fed up enough to ask the community. I have no clue what it could be, I thought it might be the C drive going out, but it's a new SSD, actually it's a replacement as the first one I bought died after about a month and OCZ sent me a new one.

I have an hp dv5215us that I have been running off a power cable with no battery for quite some time now, hooked up to a secondary display, a Dell E151FPp. Every now and then I will unhook the secondary display and take the laptop with me to work without issues. Last night I popped my Win 7 install disk while running XP to install, clicked what I needed to, and let the install disk run. Now that Win 7 is installed, I am running into the following two issues:
1) When the secondary monitor is unplugged, the computer will not power on, let alone boot. No blue lights, nothing.
2) When the computer is on and I unplug the secondary display (I learned the hard way), the laptop powers off instantly, as if I unplugged it from the power source.
I looked in device manager under monitors and it only shows one. I am getting mirror screens now, and under the display options, the resolution options available to me look like those for the secondary monitor, not for the laptop monitor. I installed Windows 7 with the secondary plugged in.
I bought a new battery for the laptop online last night. I know it sounds like a hardware issue rather than an OS issue, but the laptop and secondary display didn't move anywhere since it was running without issues in XP, so unless there was some kind of short or something while the installation was taking place, I can't think of why this would be happening.
Any suggestions?

I"m new to computers, so I will try to be clear as possible.But I have a question about my pc.I turned on my pc and i heard the fans, but the sound was too long and went from low to high. And stops.Then my monitor did turn on, I saw a little message.Then all of the sudden it goes to sleep mode (orange button).After that my system cabinet has that same sound when I turned it on. And stops.

My computer has been doing this for awhile...I've had it for over 4 years and it works fine but it seems like lately my computer will freeze for a second and then it makes a suddle click sound then it comes back...Computer is not making loud noises or anything but when it freezes it sounds like it is switching gears before it works like normal again.Someone told me Memory issue and I have Memtest but not sure how to use the ISO.

When Windows 7 shuts does my monitors after 15 minutes of inactivity, it crashes completely when I bring it back.
So when I left for breakfast this morning and came back, I moved the mouse to get the display on again...the mouse moved around for a few seconds then stopped. Freeze. No task manager nothing...I had to pull the plug and restart the computer, and it works fine.
I replicated this as well. I just left it sitting there for 15 minutes, the monitors went off. I went to bring it back and again, freeze.
Only programs that I was probablly running during both instances are uTorrent and Firefox (No-addons, one maybe two tabs.)
My screen saver is set to "none" if that helps. For now, I can alleviate this issue by setting the "Turn Display Off After" to "Never" in the power settings, which is fine with me. I just thought I'd post this up.

During my usage of Windows Seven, I have found one very annoying problem which is freezing. It doesn't freeze for more then 2 seconds, it freezes and then it goes back to normal instantly but it gets very annoying. Because sometimes the freezing stays for like 2 seconds and the sound totally freezes up also it does a peeping sound like its stuck....
Also I have been reaching about this problem before posting here.. they are saying that it my be cpus or memory and and I know that is not my problem because I recently updated my PC with a new graphic card. Before i did that it wasn't freezing..
I updated from a radeon X800 ATI to a HD 4770 which is clearly its better and before I switched graphic cards it worked fine and now its not right now Please I really need a fix for this issue.

I went to sleep last night with the computer on (Windows 7 7077) like always and this morning it's still on but none of the usb devices are working, monitor doesn't come back from sleep state but the fans on all the components are still spinning. I tried hard rebooting 3-4 times and still nothing. I let it sit and cool off for a bit and still nothing. Anyone know what the problem could be?
I was thinking it was the motherboard but then wouldn't the ethernet light be off if the board wasn't working? The only thing on the computer the has been overclocked is the CPU which I took from 3.0ghz to 3.8ghz and it's been running fine on the stock cooler for the past 6 months almost and then bam it's like this. I don't think it could of been over heating as the temps usually run 30C at idle and 50-60C at full load and the side is off of it.

How do I stop the screen resolution from reverting back to 800 x 600 when switching to external monitor? Intel(R) Graphics Media Accelerator Driver for Mobile thinks the optimal resolution is 800 x 600 when it's actually 1024 x 768. How do I make it see 1024 x 768 as the optimal resolution and make it the default for the external monitor?

I am going to preface this by saying that this has *nothing* to do with restoring from sleep or hibernate modes. In searching for an answer to this issue, I found way too much related to that.
My problem is simple. Occasionally (~50% of the time) when I turn the monitor back on after shutting it off, it will stay blank and not really turn back on. It makes no difference how long the monitor has been off. After turning it back on, the power light is green, indicating there is a signal, but the screen is black.
Again, the computer has not slept or hibernated. I simply shut off the monitor and later come back to turn it on. The same thing will happen occasionally if Windows shuts the monitor off after the configured time. (I did that last part as a test; I typically do not automatically shut it off.)
Specs:
OS: Windows 7 64-bit
CPU: Intel Core i7 860
MB: Asus P7P55D
Memory: 8GB - Corsair CMX6GX3M2A1600C9 (2 x 2 x 2GB)
Graphics: NVIDIA GeForce 8800 GTS 640MB
Monitor: Chimei CMV 221D
NVIDIA Drivers: 8.17.11.9562 (11/20/2009)
I originally thought it was the OS that was hung. However, I was able to go into the start menu and restart ("Start" -> "Right" -> "Right" -> "R"), so I know the OS was there responding to my commands.
Attempts to fix:
- Restart the computer. This worked.
- Shut off the power to the monitor and turn it back on. This works most of the time.
- Lock and unlock Windows. This works after a few tries.
- Hit CTRL-ALT-DEL followed by ESC. This works after a few tries.
So, I have a fairly simple work around now. So this is only a minor annoyance. Hitting CTRL-ALT-DEL then ESC does seem to work. I don't think it is a placebo because I waited 5 minutes and it did not come back, but after 2 cycles of that, it came back. I think that fixes it because it causes full screen refreshes.
Does anyone have any ideas or has anyone seen this before? The drivers are recent, but I noticed this with the clean-install Windows 7 drivers for this card as well. This is a very clean and very recent install (3 days). I never had this problem with Vista 32-bit, the same graphics card, recent drivers, but different CPU/motherboard/memory.

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

Lately, its been happening when I've been playing Diablo 3, however it has happened when surfing the internet with Chrome. There is no indication of when it will happenAlways happens at random. The computer freezes completely and the sound goes on an infinite loop. Eventually it magically comes back as if nothing happened at all. No error messages popping up from my system tray(for example, I don't see a "Nvidia Driver has recovered from an error")I don't have any crash dumps/error logs to share at this moment, as I am posting from work. So this thread is a bit of a place holder for later so I can update it with relevant information if you need it[CODE]

Two PCs here, one with Windows Business other with Ultimate have the same problem.They don't crash or completely stop, nor go slow along the day. They just give me several small halts during the entire operation.Everything is up to date, during stress test no problems are noticeable but (one PC is overclocked by 40%, other is stock).Full virus check, nothing found.

I run a dual monitor setup, and I use two user profiles and switch between them throughout the day. I set up both user profiles identically, which is as: In each profile, I run multiple instances of Internet Explorer 9, so I have four or five Internet Explorer windows open with multiple tabs open within each window. I keep two IE9 windows open on my left monitor, and three open on my right monitor. I also have MS Word and MS Excel open on my left monitor, and two notepads open on my right.
When I click on Start and switch user accounts, if I go back into my first user account, my windows will have either moved off screen somewhere, or they will have moved to the first monitor. The behavior is inconsistent in which windows are shifted around, but the windows end up moving none the less, and it ruins my work flow. I spend all my time setting up the windows back to their 'correct' positions.
Switching users to the 2nd user account will cause the same consequences with the windows set up on the 2nd account, thus defeating the purpose of utilizing multiple profiles to make work more efficient. I recently switched to Windows 7 on a new computer. My "old faithful" has Vista 64 does not exhibit the window shifting issue.
I am running a new 2nd gen sandybridge system, with an asus h67 motherboard and an i7-2600. I have 16 gigs of ddr3, and Win 7 64 Home Premium. I have an ATI Radeon HD 6570 running both monitors, with the latest video drivers installed. I've encountered this issue with and without ATI Catalyst suite installed and with/without Ultramon installed.
I don't want to revert back to Vista 64 just because it will be a lot of downtime to install and transfer my profiles again on the new machine, and I'd like to stay on the most current OS regardless, but I may have to switch back to Vista if this is a known issue on 7. We use dual monitor Windows 7 setups at the company I work for (my day job), and Ive verified 3 of my coworkers also have this issue. I also replicated this issue myself on one of the work Win 7 comps.

i have a acer aspire am3802-u9062 and while playing games like sc2, world of warcraft, and multiple other games, the computer makes the humming sound through the speakers which i assume means its frozen but the monitor becomes unresposive. i've tried dusting out the inside, taking off the side, turning the back facing the open part of the room, putting a fan by the side of it, so it doesnt seem like a heat problem. i have the recent video card update. i can also watch live-streams and hd videos on Internet with ease and no freezing. im baffled and can't figure it out. also have never had a bsod.
os - windows 7
(home premium 64 bit)
cpu - intel core 2
(quad proccesor q8300)
memory - 8 gb ddr2
hdd - 1 tb
odd - dvd super multi drive
vga - nvidia geforce gt 220 1024 mb
it only started happening recently, about 3 weeks ago. i've also ran programs like advanced system care, smart defrag 2, fix cleaner, ccleaner, along with full virus scans?

I've been all over the internet trying to figure this problem out, but when I try to put my computer to asleep, it does as I described in the subject line. It's a new PC, though it was custom builtnyway, I've tried a dozen tips and tricks that haven't worked, and I'm sorry I can't remember what they all were. I've tried adjusting the Power settings, and tried changing options somewhere that said "Allow computer to sleep". With all the changes I've made, it should sleep

On startup, power comes on, the hard disc runs and the system starts to boot but after 10 or 15 seconds the system powers off. This is a sudden and repeatable event, the screen sometimes getting into 'startup repair', but always powering off before any Recovery. After removal of the harddisk, memory slots and video card, I can poweron continuously and the main fan runs ok. A second fan (video chip?) does not run. Replacement of the hdd and memory is ok but as soon as the video card is re-installed the system returns to powering off after 10/15 seconds. The video card is an nvidia gtx go 7900/7950 and I don't want follow an expensive path of unit replacement- the laptop is 4 years old, a Rock Xtreme CTX Pro (a Clevo generic laptop with a Hannstar J MV-4 motherboard.

Ok well we had some lighting today but power did not go off, maybe made some of the things flicker for half a second.After PC shut down went to go turn it back on, would boot for a few seconds but then turn off, never got the beep from the mobo or anythings..Things i tired.
-Different power supply (same thing)
-Removed CMOS and put back in (same thing)
-left all but 1 ram in (same thing)
I am thinking its the mobo but i want to be 100 % sure before i go out an buy a used one, as for some reason 1366 mobos are expensive.

I built a computer for a friend. I used the $500 build, found here: I kept everything the same except I got a core i5-2310, and a zotac GTX 560ti, instead of the ECS(due to mail in rebate). It powered on initially fine. I installed motherboard drivers and video card drivers off the cds provided. I rebooted once, and began running windows update. I noticed performance was slow. So I checked task manager and CPU usage was at 100%, and then it just turned off. So i tried to reboot it, with no luck. I removed video card thinking that uses the most juice, and it still did the same thing. Reseated everything, put new thermal paste on cpu and still same thing. System turns on for 3-5 seconds then everything turns off. No beeps, etc. Im kind of at a loss. I did think it was odd that the PSU was only 450w, and gtx 560ti says 500 minimum. Could that be the issue with the core i5 i threw in there over the celeron g530 Edit: some odd behavior I noticed. When I pressed shutdown. It said windows is shutting down, but the PC restarted. Though that was weird.also tested with my 500w raidmax psu.

I put my laptop in sleep mode before leaving to star bucks.I open my laptop and press the power buttonThe internal fans start turning as well as the disc drive, but the screen remains blank.I have heard that Windows 7 has multiple issues with the sleep mode, and I'm pretty sure laptop is now stuck in hybrid sleep? Also, I noticed that there is a hotfix for this provided by microsoft, but I would have no way to use this since my computer cannot get stuck out of this. After Researching this, I heard some people taking out the battery and holding the power button down for 30 seconds, then running it off of a/c power.

I recently opened my laptop (already void of Warranty) to clean up the dust from the FAN which was giving so much of noise. After replacing the fan - i was able to control the noise - but my laptop starts to powers down automatically. This does not happen always. I checked the below things
1) Power Supply - no issues
2) Battery - no issues
I am not sure what is causing the laptop to power down automatically.

I just built a new computer, installed Windows 7 and all that, worked great. However, recently, when I leave the computer on by itself, after a while I will come back and the computer will have randomly shut itself off. Mind you, it isn't a full shut down, such that when I hit the power button again, it doesn't go through a full windows boot, just takes me to the login screen to my user account. What also happens at this time, is that my computer does not recognize my monitor's optimal resolution. I then have to go into the control panel and hit detect every time this happens, so that the computer displays on the whole screen.

I put my Windows 7 laptop to hibernate when it is plugged to the power source. When I unplugged the laptop from the power source, the laptop powers off. The next time I turn on the laptop, it is restarted and I see the screen with a message that says Windows was not properly shut down.

I have 4 computers in my office.Out of 4,3 of them has a problem for the past 2 months.They all run windows 7.
They keep working for about 30 mins to 1 hour after which they suddenly goes into power saving mode.The monitor goes dark but the CPU light and the fan still work.Then after 10-20 seconds it automatically restarts.
When logging in after the restart,It shows "The system has recovered from a serious error".This happens every 30 mins and for these 3 systems.(I bought it from the same shop last year),But the other one works perfect for about 4 years.
I have tried cleaning the fan,sink and even reinstalled a fresh copy of windows 7.Still the problem persists.
