Current hardware:
Processor (CPU): AMD Ryzen 7 3700X
Mainboard: MSI B550-A PRO
Power supply: Seasonic Focus
Graphics card: Radeon RX 6700 XT
2 monitors, LG and Samsung
The PC was bought as a complete PC, I only added an SSD. But that was right after the purchase some time ago. So I think everything should have been connected correctly and matched in terms of power supply and graphics card.
Describe your problem:
For a few days I have had the problem that the PC or the monitors no longer wake up from sleep. A quick search shows that there have probably been problems with AMD cards and sleep mode for some time. This wasn't really a problem for me before.
After rebooting, the AMD software said that the drivers were not correct.
After a few reinstall, reboot and sleep cycles, the screens no longer display anything at all, not even when booting or BIOS.
When I switch on the PC, the screen activates but stays black, then shows no signal and goes back to sleep.
What steps have you already taken/tried to solve the problem and what has it achieved?
I uninstalled the graphics drivers via UDD (when there was still a picture) and tried different driver versions.
According to a post in the AMD forum, the problem should not occur with the Pro drivers if you use the ones from Q4 22.
Without success.
I deactivated driver updates in Windows, as otherwise an error occurred during driver installation.
I also deactivated sleep and hybrid sleep.
I reset the bios via the CMOS button. I also installed the latest version.
I have tried different HDMI and Displayport cables as well as individual monitors and all ports.
I removed the graphics card, started the computer without the graphics card, I don't think the MB has onboard graphics, switched it off again, put the graphics card back in, restarted. Re-installed the driver, but still the same.
I hope I have described the problem clearly and that someone else has an idea of what else I could try.
Thank you
A small addendum
I have just done this because I have seen that it is better to connect the graphics card with 2 separate power cables.
Fortunately, the screen came on, I uninstalled the drivers via AMD CleanUp and not UDD, rebooted, started AMD driver installation, and now everything is dark again...
