Driver Issues Installing Win 7

[Deleted]

I just built and installed Windows 7, and when Windows 7 loaded up I wasn't able to use the mouse or keyboard. I believe it some sort of driver issue, but why would there be a driver issue with a completely new Mobo and Cpu? That leads me to assume they are not supported by Win 7, if so how do I go about fixing it this or should I get Win 10 and reinstall windows on it. I don't really want to get Win 10 since I've upgraded it on my laptop and there were too many bugs and issues for me, so i reverted back to Win 7.

Any idea?

Please help.

Thanks!

I didn't find the right solution from the Internet.
