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.
