Mouse and Keyboard won't work after Win7 boot

[Need4funs]

Alright I've tried basically everything I could think of with this. I've unplugged and plugged my mouse and keyboard in every single USB port, I've tried to log into safe mode, and I've booted from a bootable USB and CD and even on new partitions they still won't work. I just upgraded my motherboard + CPU from an I5 3450 to an AMD Ryzen 5 2600. At this point I'm just desperate and don't know what to do.

Edit: The mouse and keyboard work in the BIOS, they just don't work when Windows loads up (even the numpad light goes off)

Did you re-install Windows after upgrading ?

If not you are trying to use drivers for an Intel motherboard with an Amd motherboard and that won't work.

Figured it out, certain AM4 motherboards don't support Windows 7 anymore (such as my own). Guess I'll finally have to surrender to Win10.

I tried to reinstall Windows 7 and even on the installation screen they wouldn't work. I've figured it out in the meanwhile, I tried to install a pirated version of Windows 10 to experiment and they were working fine on the installation screen. I just need to go around to getting a copy of Win10 now. Thanks for the reply nonetheless!

Of course, it's a Ryzen Cpu. I should have noticed that.

I believe you can install 7 but you have to put Usb 3.0 drivers into the install media.
If you want to try there's a good guide here :- https://kb.stonegroup.co.uk/index.php?View=entry&EntryID=629

If you post your motherboard details I'll look for the Usb 3.0 drivers for 7.
