Windows 10: how to fix system black screen with no cursor, and can't access bios without clearing CMOS...

hello, i have an issue with my bios which happened after i installed office with autoKMS in it into my legit windows which makes my system stuck on a black screen with no cursor, no motherboard splash,and no bios on every cold boot.

what i have done so far to deal with this is:
1. uninstalling office and removing the autoKMS with malwarebyte
2. reinstalling windows which works for a while, but then on a cold boot it would be a blank blue bios screen
3. force fixing my corrupted bios as stated here https://forums.tomshardware.com/threads/gigabyte-z77x-ud3h-boot-loop.1427533/ which now enables me to boot bios after clearing CMOS

system would only boot bios and windows after clearing cmos before every boot, in which i would have to change my sata configuration into AHCI from IDE

any ideas on how to fix this issue?

Wiondows 10 PC won't boot unless cmos is cleared

Hope someone can help.

I installed the Win 10 upgrade about two weeks ago to a pc running win 8.1. Everything worked fine for a few days and then it booted to a black screen no cursor. I was able to access the EUFI screen and get things up and running. Things seemed okay until
the pc was powered down. On restart I had to go through the EUFI again. The situation has degraded to the point that now in order to start the pc I have clear the cmos and reset. Has anyone ant suggestions?>

Thanks

 

Black screen with cursor after Windows "repaired" my disc

I haven't found much that can fix a black screen issue.
Here's what I try at work:
- reboot the system several times and let it sit for a while (up to 30 minutes) while at the black screen (you can try to use the computer during these times).
- System Restore point
- RESET with Keep My Files (access from the boot and it should be able to be accessed)

Beyond that I've spent weeks trying to fix these things without success.
Now (at work), we try the above steps and if they don't work - we wipe and reinstall Windows (so I'd suggest backing up the system and then restoring the Macrium image)

Good luck!
