PC monitor gets black, randomly

[hliastsek]

hi guys,

 

i am new here, so i hope that's the right subsection. I am currently facing the following issue with my computer. 

 

Randomly (eg during gaming, or browsing etc) my pc screen gets black and comes back after 2-3 seconds, at the same time a strange sound comes from my speakers (similar to the one, when you unplug them suddenly from the mobo). Given that my gpu is still new, i contacted with the shop, from which i bought it and no issues found, i also tried with a new hdmi cable.

 

My pc consists of:

CPU: ryzen 5 1600

Ram: 1x 8gb ddr4

Mobo: Msi b350 pc mate

Psu: coolermaster Silent Pro M2 1000 (yeah i know, overkill)

GPU: gigabyte rx 480 8gb

Monitor: Dell S2316H

 

Any ideas?

 

thanks for your time

Disconnects like that are power issues. Whether it's power from the cable, the cable adapter for the power supply, or the power supply itself your monitor is getting "spikes" of being disconnected.

 

Try it with another monitor to see if that's the issue.

thank you for the reply! i will try with another monitor. 

 

However, the strange sound from the speakers doesn't imply issue with the psu? (i mean that the psu does not give enough power to the gpu and all peripherals)

No. Those are just connect/disconnect sounds/"pops". It's fine. Your PSU will randomly turn off or reboot your PC if it was the problem.

might just be a loose connection.

If you have a known good cable try this. If not touch/wiggle the connector on both ends.

Other problems might be wrong configurated software. Not sure if this is a nvidia exclusive problem or can happen on amd cards too. 

on which cable are you refering? the power cord of psu?

HDMI/DP 

Had last week the same issue (wiggle/touch the hdmi plug and the monitor went black which lead to the cable as solution) with a U2515H. Swapped in another HDMI cable and it works.  Even if the monitor displays a error with audio codec something it can be the cable/connector.

If you read the post in the Dell forum about these problems you will read about a setting inside the nvidia drives. I think this was releated to the audio part of the signal.

i have already tried with a new hdmi cable, issue still occurs
