Searching for hidden PCI devices on Windows.
Searching for hidden PCI devices on Windows.
You received your Asus Z490-E gaming motherboard and installed the chipset and LAN after updating the BIOS, but you're unsure what missing component is. Any assistance would be helpful.
Check their driver area: https://www.asus.com/Motherboards/ROG-ST..._Download/. They list VGA, Audio, Wireless, SATA, and Bluetooth options, indicating it's likely one of those ports.
During the second restart, the driver was deleted or removed, yet the "PCI Simple Communications Controller" remains marked as missing with identical hardware IDs to yours. This situation is causing confusion. Your model is Asrock Z490m-ITX/AC.
I discovered the fix—the missing component was the Intel TPM driver. I added it by downloading the Intel Management Engine driver from the motherboard download site.
