asus zephyrus

This has been going on with my laptop for a while now. Restarting and reinstalling updates do nothing, and I'm starting to fear it might be something with my hardware. I've also restored the ASUS multiple times and yielded no results. Occasionally, my laptop screen will suddenly go black along...

I have an Asus gaming laptop with rtx3070, and I just bought a 144hz monitor, but the monitor caps its refresh rate at 120 because it only uses the intel graphics. Can someone tell me how to fix this?
