windows 7 black screen after login, no desktop show up
windows 7 black screen after login, no desktop show up
- Hi everybody, I'm having trouble with my windows 7 right now, it's an ultimate version, I just shut it off last night and opened it up this morning. Everything seems to be normal util I loged in to my user. The old things happend after that, only the black screen showed up and an window pop up which shows "my computer" the mouse can be moved regularly.
I tried several ways to get it back to normal:
reboot.
reboot and login to safe mode.
change the resolution and multiple monitor settings.
uninstall and reinstall the graphic driver.
ctrl+alt+del will allow me go to the regular screen which I could go to the task manager, switch user, lock the pc, signoff, change pass word, and reboot or restart etc.
I ended the "dwm.exe" in process which would not work.
That window seems like the only hope I could access the computer which pop up everytime I reboot.
I can use that pop up window to go online and go control panel and all that, I can also run all the program just like normal. Everythings sames normal besides I cannot get the normal screen, no starup, no destop icons, no quick lunch. I could change my background picture, but I cannot use right click on the background.
Does anybody know how to solve this? I really don't want to reinstall the windows again which I just did a week ago.
I will appreciate any solution to this problem.

- This isn't an authoritative answer - I've just had this problem, sifted through the initial bogus media coverage, found a solution, and started speculating on the real cause.
Here's a workaround for the problem, though this company mis-diagnosed the problem (it wasn't an ACL problem). This fix is opaque and comes from a third party, but it fixed the problem for me:
http://www.prevx.com/blog/140/Black-Screen-woes-could-affect-millions-on-Windows--Vista-and-XP.html
Note their fix is an exe and they don't tell you what it does. I appreciate that they are helping, but they should fully disclose their fix so at least advanced users can have confidence in their good intentions.
Here's a better possible reason for why the problem occurred (a registry key telling Windows which shell to run on login was corrupted - a REG_SZ key was missing a '\0'. Sounds somewhat plausible, but the fishy part is what caused that?):
http://www.prevx.com/blog/141/Windows-Black-Screen-Root-Cause.html
My symptoms & observations:
I ran into this problem on a Win7 laptop that was upgraded from Windows Vista Ultimate. I log in, get a black screen, and Windows never proceeds to setting up my desktop, etc (ie, Windows never launches explorer). Running the fixing tool from Prevx did solve the problem, however their diagnosis for the cause of the problem was wrong (their initial hypothesis was the ACL's were incorrect and implied Windows Update patches broke it, but that was wrong. They followed up with the non-null-terminated string hypothesis). Before running Prevx's tool, the registry key existed, RegEdit visually displayed the expected value (explorer.exe), and the ACL's were fine. Yet, of course, I couldn't successfully log in.
My pure speculation about the cause:
So if the missing '\0' hypothesis is correct, and if the Prevx tool deletes & recreates the value in the registry key, obviously that should fix the problem. (FYI - look at the MSDN docs for RegSetValueEx for a note about the lpData parameter needing a '\0'.) But that doesn't explain how the value got messed up in the first place - I don't go around removing terminating zeros from REG_SZ values for fun nor profit. Sounds like either random corruption, or more likely, something wanted to run something when Windows boots then incorrectly undid their change to the registry.
I saw that some MS security folks suggested this could be caused by malware (http://blogs.technet.com/msrc/archive/2009/12/01/reports-of-issues-with-november-security-updates.aspx). Operating under that hypothesis, I ran Forefront on Wednesday using the current signatures, but it didn't report anything. That may not spot a novel virus or rootkit, of course.
Another wild guess - perhaps the act of installing certain classes of patches could cause the problem, due to a (hypothetical) bug in Windows Update. Windows Update does something on boot up to configure patches, and it looks like this happens after login but before Explorer is running. Perhaps Windows Update itself could be editing this registry key to replace the shell with another program that configures patches (or options to explorer.exe?), then replaces the registry key again to point back to explorer after patches have been installed? If that's how it works (which is a big guess), then maybe when WU restores the registry key value to explorer.exe, it doesn't reset this reg key appropriately on Win7. Of course, I would have expect to see a bad value for this reg key in RegEdit if this were the case. I didn't - perhaps there were some unprintable characters in the string, or I've empirically shot down my own wild guess.
Note - my problem occurred on a Windows 7 Ultimate machine that was upgraded from Vista Ultimate. Perhaps something during upgrade may have introduced some registry corruption that didn't show up until another value in the registry was changed later?
BTW, to confirm the fix & narrow down this fix, perhaps someone w/ a broken machine can reboot into Safe Mode, run RegEdit, delete HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon\Shell then recreate the Shell key as a REG_SZ key, with the value explorer.exe. If that works, that could help confirm the cause and allow us to give standalone instructions for a fix that we can have more confidence in (as opposed to telling people to run an exe from a third party).- Proposed As Answer byBlair BriggsMVPFriday, December 04, 2009 6:40 PM

- I experienced this problem today after installing an application called "Neatscan to Office 1.0". The program appeared to install correctly and documents could be scanned into Office 2007 programs.
Upon reboot I encountered the "Black Screen" along with the message "The procedure entry point DwmHintDxUpdate could not be located in the dynamic link library USER32.dll." Attempting to manually start explorer.exe was unsuccessful.
System restore to a point a couple of hours before the install, fortunately, corrected the problem.
Watch what you are installing. Neatscan claims Vista compatibility, but does not appear to want to play nice with Win7.

- I'm on Windows 7 Ultimate, a brand new install (not an upgrade).
There was a lot of "press" online, even from reputable technical sources, around this past Thanksgiving about prevx's claim and that it was a hoax and maybe even dangerous. I held off for a couple of weeks, hoping to see Microsoft come out with some sort of statement acknowledging that our experiences were real and at least begin working on a solution. I never saw one.
I eventually decided to repeat what Brian had discovered and done, running the prevx.com fix (http://www.prevx.com/blog/140/Black-Screen-woes-could-affect-millions-on-Windows--Vista-and-XP.html). I haven't had the problem since and it's been almost two months. Based on this, I recommend others try it too.
My thanks to Brian's experiment and recommendation. With Brian's link from Microsoft posted here, I had reasonable confidence I wouldn't mess my system up.

- I had the same problem, until a few minutes ago. My problem was that I had a NAS box set up on my local network, and 3 drives mounted and mapped the the Windows machine. I was getting ready to reinstall, when I tried rebooting the machine without networking in safemode.The NAS was responding to a certain point, don't know which, didn't care, rebooted it (It was a QNAP Turbo NAS 219P) Then tried again, now that Windows didn't try to map the drive, explorer worked once more!Problem: Windows explorer was trying to mount these and map them, but timed out a dozen times or so, ending in a malfunctioning explorer.Test: Pull out ethernet, or turn off router before login, see if it helps, if it does, use fix. If it doesn't, this was not the issue and I cannot help.Fix: Restart whatever machine you've got mapped to your machine, or turn it off, it's gotta need some repair.

Hi Perfect710,
I noticed that you tried to access Safe Mode. Does the issue occur in Safe Mode?
Also, please open Control Panel -> Backup and Restore -> Recover system settings or your computer -> Open System Restore -> follow the wizard to restore the system to the state before the issue occurred.
If the issue persists, please perform the steps below to add explorer.exe process.
1. Press Ctrl+Shift+Esc on the keyboard to bring up Task Manager.
2. Click File -> New Task (Run…)
3. Type explorer.exe and then press Enter.
Hope this helps.
Regards,
Linda

- Hi, yesterday I installed Windows 7 and after a few updates and re-starts I now have the same problem.
I have no idea what caused it and how to cure it!
I do not want to start explorer manually, each time I logon.
Very frustrating. - Linda,
As I reported above this works but is not really a cure for the problem.
Regards,
Marinos. - Linda,
To answer your question, I get the same issue with Safe Mode!
Also I created a new user to see if this was related to the user account but I observed the same thing.
Hope this helps. - I have the same issue on my Toshiba NB-205 netbook running Windows 7 Business (Pro?). ON Friday (11/27) it was working fine. Then I got prompted to activate with Microsoft so I did. Then i got this problem with a black screen. It happens whether I'm logging in under my user account or an admin. It happens under safe mode, too. Explorer.exe was missing from the Windows folder so I copied it there from another computer. Still doesn't launch when I login. I checked the registry key and it's sure in there (HKLM\MS\Win NT\WinLogon under the SHELL command)
If I login and activate the Task Manager I can manually start Explorer.exe and things seem to be fine but this is hardly a good solution for an OS.
What happened to Windows 7 and how do we get this fixed? - I have also been getting black screens lately, but not exactly as you describe. Several times the last days I had some explorer window stop responding. When trying to kill it, I get a black screen, and have to use the power button on my computer to restart Windows. When trying to kill the explorer window, I get the option to try to restart explorer (this is what I select), but it don't work. After I try this, everything is black, and nothing works (not even the mouse).
I am running Windows 7 Ultimate.
In my event viewer, under "System" I now get an error when starting up my pc.
"The Power Control [2009/09/11 00:28:09] service failed to start due to the following error:
The system cannot find the file specified."
Can this have something to do with the problem ?
(just trying to provide as much info as possible, so this problem can be resolved).
- I have the same problem on my home machine. I'm getting various incarnations of this problem:
* after boot, logging into an account simply shows the accounts background and never goes on.
* at the logon screen, if other users are logged on, trying to log into another account claims that there aren't enough resources to log on, which is bogus (4GB machine) and nothing running besides a browser on the other account.
Cheers, -MaF (Manuel Fahndrich) - On my Vista 64 home machine I had this black screen also. It started AFTER I tried to do a restore to a previous point. I did the restore because my first indication of an issue was OneCare would not start. I also noted that I can no longer run a command prompt as administrator either. All of this seems related if you read the information from Prevx on the issue.
For the record, safe mode appeared to boot fine. But OneCare won't start in safe mode so I couldn't test it.
Using the fix from Prevx I was able to get my screen back but the same issue with OneCare now exists. I suspected corrupted files but I now suspect a permission issue. I also noticed that the program Steam from Valve stopped working but I just ignored that until now. I am having the same problem from time to time, I couldn't figure out what is causing it to happen so therefore I don't have a reliable repro (I am using Lenovo X61 tablet).
My workaround is;
1. Boot to Safe mode with networking, then logon with my account to corporate network (this makes it boot and show the desktop in my case)
2. Restart and boot normally (which makes the problem go away and make my desktop re-appear)
This posting is provided "AS IS" with no warranties, and confers no rights.- I seem to have the same and perhaps worse. Symptoms don't match exactly, however. Received a patch on Nov 24 or 25. Upon reboot the computer (laptop) has a totally black screen. Not even the bios startup stuff appears. That doesn't seem to match other peoples' symptoms, and I wouldn't expect an O/S patch to be able to prevent the screen from powering up at all during boot.
However, the timing is impeccable. Received the patch, let it reboot the computer, and the problem started immediately. I was able to connect a separate monitor and see everything fine. Using the separate monitor, I can find no hint of the problem - other than the laptop screen not powering up.
Did a lot of troubleshooting with HP support (system restore, uninstall/reinstall hard drives, a few other simple things, looked around the PC a lot for indications of trouble. After all the the problem still persisted. The laptop screen started working 1-2 days later - don't know why. I did reinstall some non-MS updates to apps after the restore. - I too experienced the 'Black Screen of Death' on Win7 Pro. What happened is that my screensaver would kick off, the screen would go black and then would not come back. This happened soon after installing the updates. No matter what I tried the computer would not respond. I installed prevx's fix last night and it seems to have corrected the problem thus far.
- I had a very similar issue to this. I just bought my computer two weeks ago and had this happen the night I set it up. I first happened when I restarted. I called HP and they had me press f8 until the bios menu popped up. I was then able to restore default settings. I had to do it twice form Windows to even boot. It's only happened once since then, and again it was after I restarted. I used the same method to get it going and have been ok since... I'm guessing it is related to all this.
Win7 ultimate, updates were disabled from day 1 and no malware/virus on the box.
What I see is that the LCD lamp is turned of while the screen is on, this is my Black Screen of death. I was able to see what was going on in the screen by lighting the screen with an external lamp I had on my desktop. I noticed the monitor refresh rate was set to 59 Hz instead of 60 Hz which is the normal setting it should have had.
My guess is that this is definitely something video related, possibly in the way the monitors are being detected or something like that.
Also, there's a very nasty USB bug that prevents my mouse (and I tried 3 different ones) getting detected. From half the times I turn on the PC I need to disconnect and connect again the mouse in order for it to be detected.
Both bugs were seen on a desktop and a laptop I own.
Cheers- Linda,
I am having the same problem as these other people.
I purchased a new laptop a few weeks ago and decided to replace the vendor-installed Windows 7 Home Premium x32 with Windows 7 Home Premium x64. I activated the OS at that time. A couple of weeks later, as at least one other person who's commented on their experience, I was then prompted to activate the OS AGAIN! I've never seen this happen before. I decided to use the phone method and was able to activate it. Since my purchase there have been MSFT updates that I've installed.
I'm not saying what is causing the black screen but this has happened to me at least 3 times now. I've always forced the computer off and then rebooted successfully. (I didn't know about the Task Manager trick.)
Whether this is a problem introduced by MSFT or not, I would expect MSFT to listen to their customers, believe them, take this seriously, and do something about it (rather than generally telling the world that there isn't a problem). Give us a diagnostic. Try to simulate our experiences. Do something.
Jon - Add me to the list of the "Black Screen of Death." I have had Windows 7 Home Premium since 10-24-09. I have kept current with Microsoft updates. Yesterday, I experienced the same problem. The computer booted up to the User Account screen. I logged in and at that point the screen turned black. So far, I have only been able to resolve it by logging off through the Control, Alt, Delete keys and restarting the computer.
I have a Radeon 1300 video driver if it relates to this problem. Either Windows 7 has a bug or one of the later updates in November created the problem. Microsoft denies the problem is related to these updates. They should investigate the problem again. It can't be ignored.
Al - This isn't an authoritative answer - I've just had this problem, sifted through the initial bogus media coverage, found a solution, and started speculating on the real cause.

- I had the issue after a clean install of Win7 Enterprise. I could not get the system to boot into Win7 normally. The system would go to a black screen following the password entry. I could get into safe mode and was able to recreate the Shell key. Next reboot, I could get back into Win7. However, my wireless Microsoft mouse and keyboard have stopped working. I may be forced to reboot and if I recall, this it what started my problems initially.May be a USB / motherboard driver update?

Restart your PC and press F8 durring the startup. When you get options chose Safe Mode.
Click Start, click Control Panel, click System and Security, and then, under System, click Device Manager.
In the list of hardware categories, expand the Display adapters category.
Right click on your display adapter and click Disable.
Restart the PC normally. See if you can now get to your desktop. If that works you are working with a video issue. If not there are other steps you can try. - Raleej3, thanks for the suggestion. Lately, it has stopped. The black screen happened twice last week. I will, however, keep a record of your advice for future use should I encounter the problem again.

Hi everybody, I'm having trouble with my windows 7 right now, it's an ultimate version, I just shut it off last night and opened it up this morning. Everything seems to be normal util I loged in to my user. The old things happend after that, only the black screen showed up and an window pop up which shows "my computer" the mouse can be moved regularly.
CTR+ALT+DEL then go to task manager then new task then type in explorer.exe then it works. Got it from someone else down below i tried it and now it works. It did that because i accidently ended the process in task manager. I thought i had a virus but i didnt
I tried several ways to get it back to normal:
reboot.
reboot and login to safe mode.
change the resolution and multiple monitor settings.
uninstall and reinstall the graphic driver.
ctrl+alt+del will allow me go to the regular screen which I could go to the task manager, switch user, lock the pc, signoff, change pass word, and reboot or restart etc.
I ended the "dwm.exe" in process which would not work.
That window seems like the only hope I could access the computer which pop up everytime I reboot.
I can use that pop up window to go online and go control panel and all that, I can also run all the program just like normal. Everythings sames normal besides I cannot get the normal screen, no starup, no destop icons, no quick lunch. I could change my background picture, but I cannot use right click on the background.
Does anybody know how to solve this? I really don't want to reinstall the windows again which I just did a week ago.
