BSOD IRQL_NOT_LESS_OR EQUAL

Hello everybody.
one fine day i don’t know when, a
BSOD with IRQL_NOT_LESS_OR EQUAL appeared on start-up

I’m using my alternate computer requesting for help. I do not wish to reinstall my HDD because i have not backed up my files in a while.

Microsoft explained my problem to be caused by a new driver or driver software uninstalled properly. heres the twist, i didnt install anything since last year.

please help, thx
