SignalRGB Stopping PC From Shutting Down

Quick summary: SignalRGB is stopping my PC from fully shutting down.

Long summary: I have been using SignalRGB for a couple of years with no issue. However, two days ago I was able to get an Asus Tuf 5080 OC card for my system to replace the 3080 TI I had been running. Ever since then, I found that my computer wouldn’t fully shut down/reboot. When I say this, I mean Windows appears to shut down, but my lights and fans never turn off. Monitors register no signal and go to sleep as expected, but the PC never turns off. So I have to hold the power button to turn it off. This also means I can’t restart my PC as it never gets to the point where the machine tries to start back up.

At first, I thought this was maybe a side effect of the new card with drivers and/or BIOS, but even after updates, that never resolved. So I started turning off apps that automatically run at start up one by one. Once I stopped SignalRGB from starting up, my issue vanished. I turned everything else back on, still no issue. I turned SignalRGB back on, issue returned.

At that point, I did a full uninstall of SignalRGB, and the system was fine again. Lastly, I did a fresh install of SignalRGB with updates, and the issue returned.

I am speculating there is some issue between SignalRGB and the 5080, as this didn’t start until I put the 5080 card in, but I can’t say with 100% certainty. Has anyone else seen this issue? Is there something I can do to provide logs that might help troubleshoot this? Any help is greatly appreciated!

I have same issue with 5070!
Did you figure out how to fix

I did not. I ultimately replaced the main PC with a new one, put in the same 5080, and now no issue. So maybe a combination of factors caused it.

Thanks for reply, I have aorus elite b550 with Zotac 5070 and doing exactly as your post outlines!
What MB did you have ?

Now that is interesting… I was running an Aorus Master X570 (rev 1.1) with an AMD 5900X and fully up-to-date BIOS. My new motherboard is a MAG X870E Tomahawk Wifi with an AMD 9950X3D. The X870 chipsets aren’t supported yet by SignalRGB, so I wonder if that’s why I no longer have the issue.

Hi, i got exactly the same issue, i have a Gigabyte Aorus B550 ITX (5700X3D) and a MSI 5070…

Same issue, Aorus B550 Elite v2, 5800X3D, 5070 Ti.

Same problem,RTX 5070ti , B550 Aorus.. No fix, tried BIOS,chipset drivers,fresh windows,older gpu drivers..
