Monitor turns off randomly mid game and won’t turn on unless PC is restarted

[Kradlox]

My friends pc recently is having issues where the monitor randomly turns off and won’t turn back on again unless he restarts his PC. The PC remains on but the monitor doesn’t turn on again and the only way for it to work again is by restarting the whole PC. Any idea what is causing this?

Faulty display cable? If it requires a system reboot and not just simply unplugging the display cable and plugging it back in or powering on and off the monitor though, that could mean the GPU is what is black screening not the monitor.

It's so weird because it's been working perfectly fine for a couple days now

There has been a faulty NVIDIA Driver causing this issue with specific GPUs combined with specific monitors when connected via Display Port I believe. Make sure that his GPU drivers are up to date.

Nah his GPU is a Sapphire Nitro RX580 8GB

I built the PC for him and I was literally stress testing it and everything at home and it worked perfectly fine. Even when I got to his home, I stressed tested it using the AMD Adrenalin one.

Then for now try swapping the signal output ports on the GPU and the input on the monitor, in general what @SpookyCitrus said is something I can fully agree with.

Alright I'll keep you lot updated after he gets back to me and hopefully find a solution. Pray for me guys

Monitor "turns off". 

 

Can you define this? Actually fully powers off or just goes black? Does he see no signal or something similar on the screen? 

 

Identifying these details are important. If its fully turning off now that its in a different location plugged into different power, I'd be concerned with the power cable and/or the outlet its plugged into.

I'm trying to contact him but he's taking so long but he told that it says HDMI and doesn't display anything. The monitor stays on but nothing is outputed.

[Kradlox]

I've just seen it. The screen goes black and it says HDMI NO OUTPUT and nothing is displayed. It happens here and there so we can't really see the pattern.

Okay update really weird. The screen turns off and nothing is displayed but the audio and sound is still playing on his speakers. Any ideas what's wrong?

Replace the cable, try different ports on the GPU, swap between DP and HDMI.. those are all the basics. 

 

At that point, DDU, wipe display drivers and install the latest fresh. (tons of youtube and written tutorials with how to do this)

 

Still happening? Outside of trying the GPU in another PC to see if the problem follows the GPU, you'll have to assume the GPU is faulty.

Event viewer might have something. Can you use different pcie power connectors from the psu?

[Kradlox]

Update he’s been using it for over a couple hours now. Changed the port plugged into the graphics card and tried to recreate the issue. Nothing happened. Will keep things updated if it happens again
