Blinking screen issue [10.13/10.14/GT730]

Hi !
So I have an issue with my hackintosh (that makes it unusable, really)

It's that the screen will go black for like 1/2 seconds every 5 minutes or so (depends, sometimes it can go as far as 5 per minutes)

I found a video showing the issue (not mine, but that's exactly the same thing that's happening to me):

DELL Optiplex 7010 Mini Tower
Intel Q77 Chipset
Intel Core i5 3570@3.4GHz
Gigabyte GeForce GT 730 2GB GDDR5 REV 2.0
12GB DDR3 1600MHz
macOS High Sierra 10.13.6

Someone pointed out it could be a power issue, but I really don't think it does, even tho the power supply recommandation for the GT 730 is 300W, and the Optiplex PSU is 275W, the power supply recommandation is really often overkill (275W = 77W i5+25W GT 730+2 SSD and 1 HDD, doesn't make 275W)

I tried both with Mojave and High Sierra, but no matter what, it does the same thing, and also, I think it's important to say that I had the EXACT same issue on my Dell Optiplex 780 (Core 2 Duo), so I believe that's a driver issue

I tried with both OS X driver and NVIDIA Web Driver, it does the same thing, but with the webdriver, I don't have working HDMI audio (oddly enough)

I'm using the latest version of Lilu+WhatEver Green, here's my CLOVER folder:

Okay so I think that's it

Thanks a lot to everyone who will take the time to help me with that
