Blank screen during startup with triple monitors

[Nicholas Oh]

Current Scenario:

   Main Tower Specs:

• i7 8700K with H100i V2
• 16GB GSkill TridentZ
• GTX 1080 (Zotac AMP Extreme)
• MSI Z370 Krait Gaming
• WDC Black 512GB SSD and 3TB Seagate Barracuda
• 650W G650M Corsair PSU
• Logitech G213 Prodigy with Logitech M331 Silent Plus
• Windows 10 Pro 64-bit

   Monitors:

• 2x LG 25UM58-P on the sides
• 1x LG 24MP88HM-S on the middle

Issue:

• Every time I start my computer up, the three displays show the windows loading screen and then remains blank for around 10 minutes. They look like they are receiving the signal from my GPU but doesn't do anything at all. After around 10 minutes, the computer just restarts and it repeats all over again. I have tested that one single monitor plugged in to the GPU works.

Notes:

• During the windows loading screen, my keyboard RGB lights up. But, after that (during the three displays being blank), my keyboard lights turn off or seem to be disconnected, odd.
• If I plug in only one monitor to the PC, the display lights up and everything seems normal.
• If I plug in only one monitor, wait for it to light up, plug in one more, and then the other one (sequentially one after the other), all the displays work no problem.
• I haven't updated ALL of my drivers because my internet is extremely slow
• I am using 2 DisplayPort to HDMI adapters for the two 25UM58-P monitors because all my monitors use HDMI and my GPU only has one.
• Sorry if I made any mistakes, this is my first post 

 

Any advice will be greatly appreciated, thanks in advance!
