Hello and welcome to PCHelpForum.

Open your Device Manager
click on View ... Show hidden devices

Click on and Delete (with the Delete key) any devices that have a ? or ! in front of them.
If the Device Manager has an "Other" device category, open it and Delete any devices in the "Other" category.
Now, reboot.

The reboot will force Windows to refind the deleted devices and hopefully see them for what they are.
After rebooting, give Windows time to locate and properly install the deleted devices.

Go to the Device Manager and verify that all your devices are listed correctly.
