Question GPU disappeared after a Windows update ?

[Diego Marllon]

I bought an AMD RX 580 2048SP GPU.

I connected the video hdmi to the motherboard instead of the video card. The Gpu worked normally for 2 days until I updated windows 11 via windows update and it disappeared from cpu-z, system manager, adrenaline. However, the coolers are still running, but when I connect the cable to the video card, the monitor gives no video signal. I've tested various solutions I've found on the internet and none of them have worked. Here's a list:

• uninstall drive via ddu;
• returning windows update to the previous installation;
• restoring the system to a date when it worked;
• formatting the computer;
• changing the cable;
• and installing the specific drive manually.

Nothing works, all the solutions I found on the internet didn't work, that's why I came here. I believe that the way the problem occurred, it must just be a software problem.

Did you try resetting CMOS and/or disabling IGPU ?

Just to clarify a point: If you plug into only the dedicated GPU, if you clean boot your PC, do you get video output for the splash/BIOS, or are you a blank screen the entire way through?

Other then that: I know plugging into the iGPU can confuse Windows and it sometimes takes a reboot or two for Windows to switch over between devices (went through this with my father recently). But at PC boot plugging into the dGPU should be giving *something* if it's working. And plugging into the iGPU certainly shouldn't break/disable the dedicated one.

I haven't reset the bios or disabled igpu. If I disable igpu, won't I lose the video signal for good?

black screen throughout the process, however if I switch the hdmi cable from the gpu input to the basic input on the motherboard, the computer is on and working normally. It just doesn't have the gpu.

f you disable IGPU it's not permanent, only until CMOS reset, IGPU is always default. Instead of IGPU, PCIe should be set as default display device.

Ok, i'll try now

Nothing worked, do you have any other suggestions?

Final solution, reinstall Windows this time with CPU and monitor connected to it.
