B590 boots to black screen w/ cursor in normal, boots to safe mode OK (Windows 7 64)

Hi folks!

Unfortunately, my 2 year old pushed some buttons on my Lenovo B590 laptop and something isn't right. Upon start up (Windows 7 64), I get a black screen with a moving cursor. Ctrl+alt+del doesn't bring up the task manager.

I double checked the boot order in BIOS and that looks OK.

Restarting in Safe mode works.

I also updated the video drivers, and (strangely) I was able to restart in normal and everything looked fine. However, when I restarted again after that, I was back to the black screen in Normal.

I've been Googling all morning, and done what I've found. If anyone else has any other suggestions, I'd be grateful for them. And if you have any questions for me, please don't hesitate to ask.

Thanks!

Re: B590 boots to black screen w/ cursor in normal, boots to safe mode OK (Windows 7 64)

Hi dgroyal , 

 

Welcome to the Community Forums.

 

The way you have described it , seems issue is with the video driver and that Windows automatically updates the drivers on its own automatically. 

 

With safe mode with networking , download the video drivers for your system and save it on the desktop. 

Go to the device manager to rollback the driver first and turn off Windows 7 Automatic Driver Installation.

Restart the machine and see how it goes. 

 

Else proceed to uninstall the display driver and reinstall previously downloaded driver and update it manually on the device manager. Turn off automatic update and restart. 

 

Update us how it goes. 

 

Regards

Re: B590 boots to black screen w/ cursor in normal, boots to safe mode OK (Windows 7 64)

Thank you for your help!  I took your general suggestion, but I did a couple of things a bit differently and I think things are working.  I've restarted 3 times in normal so far.

 

In case someone else has this problem: I followed the steps to prevent the auto-update of Windows 7 Professional drivers here: link

 

Then, I tried uninstalling and re-installing the driver, but I got the same black screen at start up.  Safe mode still worked, though. 

 

Then, I uninstalled the driver and just restarted the computer, without re-installing any driver.  It restarted in normal mode correctly.  I got a message that it was trying to update the driver but was prevented by a policy change (which I had made per the link above).

 

I'm still at a complete loss as to how a toddler pushing a few buttons could have affected this, though...

 

Thanks for your help!

Hi dgroyal , 

 

Greetings. 

 

Good to know that it works for you.

 

I think you owe your two year old kid a nice treat and a big hug since it was Microsoft that caused this . 

They have placed automatic update on default for the drivers in Windows and now is a challenge with Windows 10 since this feature to turn off is not readily available. 

 

Visit our community at anytime for your queries and likewise sharing your thoughts with fellow members.

 

Cheers

B590 boots OK in safe mode (Win 7 Pro 64), black screen w/ cursor in normal boot

I posted about this yesterday (link removed) and thought it was resolved, but it isn't.

 

My 2 year old pushed some buttons on my Lenovo B590 laptop and upon start up (Windows 7 Professional 64), I get a black screen with a moving cursor. Ctrl+alt+del doesn't bring up the task manager.  Restarting in Safe Mode works fine.

I double checked the boot order in BIOS and that looks OK.

I also updated the video drivers, and (strangely) I was able to restart once in Normal and everything looked fine. However, when I restarted again after that, I was back to the black screen in Normal.  Yesterday, I disable the auto updating of drivers (per these instructions) and tried re-installing the drivers.  It didn't work.  So I uninstalled the video drivers, and then I was able to restart the machine several times normally, so I thought the problem was fixed.

 

It was back this morning, though.  I also tried disabling all the stuff (AVG, drop box, etc.) that runs on startup, but that didn't help.

 

Any other suggestions would be greatly appreciated.

 

Thanks!

Re: B590 boots OK in safe mode (Win 7 Pro 64), black screen w/ cursor in normal boot

I just tried re-installing the video drivers (because I had left it w/o them where I last stood).  I got an error, so I undid the changes I made yesterday when I disabled the autoupdating of drivers, but I still get an error when I try to install the driver.

 

Specifically, it says "The setup program failed to install one or more device drivers.  Setup will exit."

 

At this point, I'm starting to lean towards reformatting and re-installing Windows...

Re: B590 boots OK in safe mode (Win 7 Pro 64), black screen w/ cursor in normal boot

OK, the strange saga continues -- I brought my laptop to work today, and when I started it up, it started up normally.  I brought my external drive, so I'm going to back everything up with an eye towards reformatting / reinstalling windows.

 

I'm still open to any suggestions as to what could trigger the restarting with a black screen and functional cursor, with no task manager, with safe mode working.

 

Thanks!

Ok, that one normal restart was all I got.  Upon restart, I was notified that the VGA driver had been installed automatically (because I'd re-enabled driver updates).  I restarted (to test it) and got the black screen.  Then I installed the proper video drivers from Lenovo, then I disabled the driver autoupdate, then I restarted, and I'm back at the black screen.

Hi dgroyal , 

 

Greetings. 

 

Try to perform the initial step from safe mode as previously done to restore the display .

See if method 2 here would work. Else try controlling the update for the video as explained here ( method 2).

 

Update us how it goes. 

 

Regards

Thanks!  I tried method 2 (the group policy settings) and it didn't work.
