Win7 Black screen of death with cursor on all boot modes
KSOD with cursor
I usually fix my computers (that I build) myself, but I'm appealing to the accumulated wisdom here because I'm at my wits end and trying to avoid reinstalling Windows from scratch and putting back software for a week... Needless to say I went through all the tutorials and how-tos on BSOD, KSOD, Windows won't boot and the like, especially on this forum.
My computer is running Windows 7 Ultimate x64.
Symptoms:
My computer wouldn't come out of hibernation (happens once in a while), so I forced it shut and restarted it. Since then it won't boot:
Boot in Normal mode: Black screen with cursor. Keyboard active (num, caps work), no mouse
CTRL-ALT-DEL or any other key combination = nothing
I'm able to go into the Windows boot menu by pressing F8, so:
Safe Mode: same, with bigger cursor
Safe Mode w/ Networking: same
Safe Mode w/ Command Prompt: same
Last Known Good Configuration: same
Low resolution boot: same
Leaving the black screen on for some time: nothing
What I attenpted so far (to avoid unnecessary responses and waste of time):
- Went to the "Repair options" screen (from windows boot menu):
- Startup Repair (numerous times): Disn't find any problems
- System Restore: Could not find restore point (which is false, as I have some automatic restore points)
- System Image Recover: Couldn't find image
- Windows Memory Diagnostics: no problems found
Then I went to the command prompt, and everything I tried from here on was from there:
- Chkdsk on the boot disk = no problems found. I could check that all my data (which sits on different disks anyway), is there and safe, so rescueing's not the issue.
- Windows Defender Offline: Ran that, no issues
- SFC Scan: Now this is interesting, because it will run with the usual options (/scannow /offwindir=c:\windows /offbootdir=c:\, it will report that it found corrupt files and successfully repaired them, but I think it does nothing at all.
The cbs.log file holds lots of stuff, but absolutely no sign of any relevant action - neither which files had an issue and were fixed, nor of the fix itself. I searched for the [SR] marker, and there are none to be found.
It's like SFC found problems, but could neither fix them nor tell me about it. I attached a copy of the CBS.LOG file, if its contents mean something to someone...
If anyone can help me with this, they would be my savior!!
Thanks to all
