Hey everyone.
I made this post to anyone who has the same issue as me since sadly it's still relevant.
I built my PC in November 2022 with a Ryzen 7 7700X and an Asus TUF B650 Plus Wifi. I had this problem where if i booted with stock BIOS settings, load into Windows 11 and start any game, said game crashes in 5-10 minutes with error message: "Update video drivers" pointing to the iGPU. I have an RTX 3070 in my PC so i don't know why it wants to use the iGpu. Spent a week troubleshooting to no avail. After disabling the iGpu in device manager the game crashes instantly with the same message. Updating the drives either manually or through Adrenalin software didn't help either. I updated BIOS after BIOS and tried again but the issue still persists to this day.
Solution:
Uninstalled every AMD driver with DDU in safe mode, restarted the PC, went into BIOS and disabled the iGpu.
Crashes stopped and have no problems since, but be aware if you ever need to re enable the iGpu and boot up with it, you might have to do this again.
I don't know what's causing this but it feels like if i start any 3D application at one point it wants to switch to the iGpu and it crashes.
