    Screen flickering in Windows 10 safe mode

    I haven't made any changes on my device. This screen flickering is only happening in Safe Mode.

    Windows 10 lock screen flickering and wont let me log in

    Screen starts to flicker after logging in for a while


    Hello

    This is an entirely new issue. My screen starts to flicker after logging in/turning on computer for a while, and/or if I launch an app that uses my Nvidia card (my laptop has Optimus), I'm not exactly sure which of these two causes it. For the first while after a restart, the screen appears fine. The flickering appears on desktop background + internet browser as well, so I'm pretty sure it's not a program compatibility issue. The flickering is not severe (the type that looks like horizontal bars sliding up) but it's an annoyance.

    Tried:

    • Disabling Windows error reporting + problem reporting service in msconfig
    • Restart computer
    • Resetting Nvidia global settings to default in Nvidia control panel
    • Checking for display drive updates in device manager (all up to date)
    • Checking monitor refresh rate (60Hz, can't be changed)

    Laptop I'm using:

    • i7-4700MQ 2.4GHz
    • 1900x1080
    • Intel HD 4600 + Nvidia GT750M

    Thanks for suggestions.
