Screen randomly goes black for a few moments then comes back

[vegashepliin]

I have an external monitor hooked up through the built in hdmi port and it will occasionally go black for a few seconds then come back. There doesn't seem to be anything directly triggering it as I have not been able to discover a pattern of any kind on when it happens. It happens on multiple monitors and multiple cables. I've updated and rolled back my display drivers for both the built in intel graphics and the GForce GTX 1650 that came with the laptop. I have a 13in version of the same basic laptop and it doesn't have this issue although it doesn't have an hdmi port and is using a usb-c to hdmi converter. I have another issue already submitted stating that I am completely unable to use the usb-c with any kind of converter to hook up a monitor on this (the 15in version) laptop.

Between these two issues, I'm starting to wonder if I just have a faulty GForce graphics card as it's only issues dealing with external monitors. the main display on the laptop, which seems to primarily use the built in intel graphics as opposed to the GForce graphics card has no problems at all. The GForce card is part of the original laptop i purchased and the laptop is brand new.
