randomly, screen goes black and freeze

[Javaded]

Hi, I installed macOS Sierra and High Sierra on hp8300 with GT 710 2GB LP Graphic card based on this topic:
https://www.tonymacx86.com/threads/...orking-and-easily-affordable-customac.224812/
in both os I have a similar problem.
when Im working with my Mac suddenly screen goes black.
I left my Mac running for 7 hours without touching it, it didn't have any problem.
when Im using it, it occurs a lot! I should press power button for several seconds to reset.
I installed os like this guide and Im pretty sure it is Graphic problem.
I also tried correct web driver maybe it works! but it has same sudden black screen problem.
it seems the graphic lost sending signal to lcd
what can I do?

thanks in advanced

some random freeze also happens, I assume the source of the problem is similar.
I use 13,2 as mention in the guide

@Javaded, please update your profile (personal details) with your Motherboard, CPU and iGPU or Graphics Card.
If you have a prebuilt computer enter make and model instead of motherboard (Mobo).
If you have multiple systems add them to your signature or build signature.

Profiles need to contain at least your primary system to assist others with helping you.

tnx
I have updated my profile, I think, I create this topic in a wrong place and it should be in Graphic section, if it is, please move it there to help me find the answer!

Hi Javaded,
I have an elite 8300 with a 1050ti LP that has started doing the same thing. I'm running sierra and only started seeing the problem after doing the latest sierra update. I thought it may have been an issue with the NV web drivers that I updated to after the sierra update and was about to upgrade to high sierra to see if that fixed the issue. However, I was on my windows 10 partition and the random black screen issue is happening there as well, although more frequently on macos it seems.
So i think its fair to say that it is not a macos/web driver issue or a graphics card issue either. I'm wondering if its power supply or other hardware related ie motherboard etc. I'm running via display port

Sorry I haven't got a fix for you but I wouldn't go throwing out your graphics card just yet. Do you have dual boot on yours?
