[SOLVED] HDMI no signal problem.

[EugenPlesca]

Hi, I have been dealing with this for over 6 months.After playing games like 25+ mins with 65-70 degrees, my monitor loses signal.(goes black screen)

My specs:
GPU:ASUS Expedition Radeon RX 570 OC edition 4GB GDDR5
CPU:AMD Ryzen™ 3 2200G, 4 cores, base clock 3.5GHz.
Monitor:MSI Optix MAG241CP (1920x1080, Full HD, 1 ms response time, 144Hz).
RAM:KINGSTON HyperX Fury black 8 GB (2 x 4 GB) DDR4
PSU: COOLER MASTER MasterWatt Lite 500W PC power supply.
Motherboard:ASUS Prime B450-A black.

I tried replacing the hdmi cable and it didn't work.
And I tried another monitor and it didn't work too.
I just turn off my PC to get the signal back.
The GPU has only 1 hdmi port and the monitor has 2, but I don't think the problem is from my monitor
because this happened on my older acer monitor.

The interesting thing is that when I'm playing Heroes and General at the temp around 70-75 for almost 1 hour the screen doesn't loose signal
but when I'm playing destiny 2,just cause 3,steep or other games, where the temp varies from 60 to 70, it looses signal after 15-30 min.

Any help or suggestions?

How about to try other PSU, or test the rx570, or tweak the GPU, like lower power limit, under-clock, increase the voltage, etc with software.

And make sure you update the GPU driver, and when you update the GPU driver, use DDU to uninstall the GPU driver first, then update the driver.

one more update the chipset driver too. https://www.amd.com/en/support

So, I solved the problem.I opened the GPU and saw thermal paste everywhere, I mean there was to much,
maybe it was just a factory problem.I cleaned the place and put a new thermal paste and it is not losing signal now.I can finally play on high temps.

Thanks for Help and Suggestions!
