Question Monitor no signal when gaming

[ant9398]

Hello,

When I play a games like Valorant or CS, my monitor suddenly goes black and says "no signal" during the middle of a game, and i can still hear the sound of the game, and I have to force restart my PC. It also happens to less demanding games, but less often. This issue came 1 year after I got my PC. My PC has no problem outside of gaming.

Graphics card: RTX 2060
CPU: i5 9400 F
8 Gb RAM
500W PSU

What I've tried already:
-Cleaning inside my with compressed air can
-reinstalling driver/ playing with old drivers
-remove/ plug back cables
-playing at lower graphics
- I've done the Furmark test with no problem

I'm suspecting my GPU, but I don't know exactly what is the pb with it

Thx for the help

HP 500 W

is the whole thing prebuild or did you upgrade the gpu?

 

[ant9398]

It's a prebuilt and I have it since 9 months.

I haven't done anything inside either

try to get a better cable at least, something called gold platted or certified, it's worth a try, solved my flickering issue for both of my current screens.

its not a cable issue, it only happens when I run average demanding games atleast

for those who might stumble upon this topic and have same problem:
- increasing memory clock + 700 ( vram) and overclocking my gpu + 130 made my game not crash for the first time in 2 months. Hope it stays like this.

I don't know why it worked, so if anyone interested in that matter, please share his opinion
