can't get into safe mode no matter what i do. f11 at start up computer stays on blank screen then shuts off
tried msconfig.exe boot tab check safe then restart just takes you to normal mode.
restart+shift.... advanced setting..... didn't work either.
did a reset pc from recovery partititon that didn't work did a refresh pc did recovery manager that didn't work
did a factory reset using usb flashdrive that didn't work either.
did a F2 extenstive test on all hardware passed(3hr)
having problems with not just getting into safe mode but creating a system restore point get non transient error can't update to windows 8.1 all of this stuff even after factory reset
any help i would be greatful
