Hello,
About a week after upgrading my Dell Vostro 5470 to Windows 10 it suddenly crashed and a blue screen appeared with the error message "driver_irql_not_less_or_equal"
and it didn't boot anymore until I downgraded it to Windows 8.1 from the recovery options in the blue screen.
Then, I'v upgraded it again to Windows 10 and after a week the same thing has happened.
I'm currently using Windows 8.1, and it works fine, but I want to use Windows 10...
Any suggestions?
Thank you,
Or.
