USB non-functional on OS bootup?

By agledhill135 ·
So, I've just finished a new computer build and all of the hardware works just fine. The problem I'm having is when the OS (Windows 10) fully boots up, it removes the functionality of all the USB ports. When I go into the BIOS the mouse and keyboard work just fine, as do all other USB inputs and hardware, but when the sign-in screen pops up all of the USB ports suddenly go offline. I'm hoping I don't have to reinstall Windows 10 but I will do that if necessary. Is there any way to restore functionality to the USBs on OS bootup or do I have to fully uninstall and repurchase Windows 10?

This issue could be due to corrupted USB ports.

You may try uninstalling and reinstalling the USB controllers and check if it helps.

Press Windows Key + R, type devmgmt.msc and press enter.

Expand Universal Serial Bus controllers. Right click a device and click Uninstall. Repeat for each device.

Once complete, restart your computer. Your USB controllers will automatically install.

Check the issue.

You may also try to install the latest version of chipset drivers from the manufacturer’s website and Windows Updates to check if it makes any difference.
