Same horrible Black Screen + easily movable Mouse Pointer for my Windows 7 today. (fought with it for 3 hours today)
I FIXED IT!!! - Solution:
- Reboot
- Keep pressing F8
- Choose boot from Last Known Good Configuration
- Wait for it... and it was back (still slow booting but thats been normal for over 2 years now.)
What else I did, however none of it was likely of any value:
* Unplugged all USB devices, pendrives, etc, except mouse. (Keyboard is ps2 anyway).
* During the Black Screen, hit Control-Shift-Escape (hoping it would bring up Task Manager so i could manually run explorer.exe)
* Reconnected my second monitor which i usually connected, but it has been off for 1 week while used on a new computer build im doing.
* Waited on Black Screen for over 1 hour (thought this might work since it was booting slower after installing Macrium Reflect this week.
* Multiple Reboots, all to no avail.
What I definitely did not want to do until I had tried safer stuff:
* Reinstall Windows 7
* Run System Repair from my Windows 7 install disk
* Anything that runs a program that might touch the Registry, IE cleaners.
* Any other external disk boot environment (not that they arent safe, or that i dont have, but i just haven't practiced with them enough.)
* Safe Mode - Although this is clearly the safest in this list, but most people said it didnt help, and it has potential to change stuff
* System Recovery to an earlier time - this would be fine, especially through safe mode, but i just couldnt remember how far back it would take me
(In fact, if you have this problem, try my solution first, then go backwards through this list above from the lowest one to the top one.)
What I dont think it was:
- Not a virus
- Not likely related to installing Macrium Reflect Free since it booted once or twice after that fine. (with longer boot time, which i think was related to being extremely low on disk space after the 400MB install.)
- Not likely caused by low C: disk space (but i do get slower boots the lower it goes)
What I think caused it:
When I woke from Win 7 sleep (with basically no disk space and memory topped out at 4GB of 4GB when put in sleep), it blue screened but too fast to get a code, other than to see it was related to my nvidia graphics driver
So I assume that the black screen + mouse related to the issue with the video corruption, that required last known good configuration to work again.
What I'll do now that its back up:
I have no trust that it wont happen again, since i didnt cause it to begin with, so therefore im:
* immediately copying off all extremely valuable data to a pendrive
* freeing up tons of space on the C drive (hopefully 100Gig, since its down to 19G on a 1TB drive
* uninstalling Macrium Reflect Free, since thats the last program i put on before this issue happened.
* updating and running both my Windows Defender and 3rd party antivirus (just to be safe)
After my hour of research, including all the posts in this thread, I tend to believe that tons of different things can cause the same Black Screen + mouse issue. And that each needs its own specific solution. So I dont claim what I wrote here will absolutely
help you, but hope it can. Good luck!
