How to fix Gpu not detecting

I installed an additional SSD in my laptop, but since both SSDs had Windows installed, it caused system glitches. After removing the extra SSD, the laptop runs fine again. However, my dedicated GPU is no longer being detected, and I’m now forced to rely only on the integrated graphics (Ryzen 5). I’ve already tried uninstalling/reinstalling GPU drivers and applied several fixes, but nothing has worked so far. Any suggestions?

Answer this question I have this problem too

Hi @tokito

What is the make and model number of the laptop?

Have you checked in BIOS to see if the discrete GPU can be disabled there?

What does Device manager show for the adapter or is it not even listed there?

by

I can not do it from bios as my laptop is acer nitro 5 and for device manager it has yellow caution sign on it and says [ Windows has stopped this device because it has reported problems. (Code 43) ].

Check BIOS/Device Manager to ensure the dGPU is enabled, then reset BIOS to defaults and do a clean GPU driver install (using DDU) to re-detect it.

I would have done that already but problem is that my bios has no options for dgpu or igpu as it is automatically detected by laptop which is acer nitro 5
