Gsync issue maybe, need higher powers help

Ill try to keep this post concise, but it's a long story. In a nutshell my monitors will randomly shut off with "no signal". This can happen within 5 minutes of boot, or 5 hours. Ok for the long version. I have 3 monitors, 2 connected with display port, 1 with hdmi. My monitors will shut down randomly. Unplugging, replugging won't bring them back, only a hard shutdown and reboot. I know it's not the PC because if I am in a game I can still hear sound, and myself navigating in the menus. First things first I tried a different displayport cable. I have had issues with low quality dp cables in the past, so I ordered a new good one with high reviews off Amazon. Same thing occurs. I tried all 3 displayports on my 1080ti, same thing didn't matter. I tried only one monitor at a time. Seemed to delay it a bit, but same thing. Tried hdmi only, got probably the most uptime, but again, same thing. So I rma'd my EVGA 1080Ti FTW3. In the meantime, I used my brothers R9 290. It didn't shut down, but displayed distortion/static on my primary Acer Predator 1440 144hz Gsync monitor. So I rma'd that too. I now have a new dp cable, a new 1080ti, and a my 1440p Acer monitor back since they found no issues after testing. All looked good at first, but it happened AGAIN. For some reason I wanted to try ULMB, I have always ran my monitor with Gsync turned on. ULMB on, 120hz, Gsync off. Wait a sec, it's stopped happening! (For a few hours and counting anyway) Holy hell, is this a Gsync issue or a 144hz issue, since I have to be at 120hz for ULMB to work. Either way, WTFH is going on here??? Does ANYONE have any insight as to what the hell is going on with my cursed computer?
