Question Monitors switch off while gaming but the computer stays running ?

[prezzy]

hello, I've been having an issue where when I try to play any game my monitors will turn off and display no signal but the pc is still running.
I have tried every thing I could think of, like updating drivers and after that didn't work completely uninstalling them. I pretty much tried every fix I could find on youtube and other forums with no results. After that I tried with a different graphics card and the issue was still there. Honestly, I am at my wits end with this computer but I wanted to see if someone here could maybe help me out before I take my pc to a repair shop.
As a side note the pc was built less than a year ago and this issue has now been happening for maybe 3 or 4 weeks.

Id appreciate any suggestions
thanks

the specs are:
CPU: ryzen 7 5800X3D
GPU: rtx 3060ti
RAM: corsair vengeance rgb pro 32GB
MOBO: msi mag b550 tomahawk
Boot drive: samsung 990 pro 500GB

Look in Reliability History/Monitor and Event Viewer.

Either one or both tools may be capturing some related error codes just before or at the times the monitors/display "turn off".

How old is the PSU? History of heavy gaming use?

Hey, I really appreciate that you wrote back.
I just had a look at the event viewer and I'm really not sure if I am missing something but all I can see in the errors are windows not shutdown properly, and these are from when I've restarted the computer after the monitors switched off. If I'm being honest I am not too sure what to look for in there.

As to the PSU I bought everything brand new about 10 months ago, Id say its been casual gaming kind of use a couple hours after work and maybe a longer session here and there over the weekend.

Go back a step and start with Reliability History. Much more end user friendly.

Event Viewer requires more time and effort to navigate and understand.

Clicking any given error will provide more details. The details may or may not be helpful. Look for patterns and make note of the numerical error value.

= = = =

If most of the errors are "not properly shutdown" then a loose connection is a likely culprit.

What you can do.

Power down, unplug, open the case.

Carefully clean out dust and debris.

Verify by sight and feel that all connectors, cards, RAM, jumpers, and case connections are fully and firmly in place. They can and do work loose due to vibrations along with heat related expansion and contraction.

Gently rock and wiggle back into place even if something appears to be in place.

Also use a bright flashlight to inspect for signs of damage: bare conductor showing, melting, corrosion, loose or missing screws, cracks, leaking components, pinched or kinked wires.
