By "working fine" do you mean, you just got to the BIOS with the WIRED-USB keyboard?
If, yes, maybe there's a bad connection, somewhere.
You previously formatted the HDD, so there is no OS to boot to.no i mean before this all happened. I got everything into the new case and it worked then the keyboard and mouse stopped working. so i looked up some answers ONLINE tried them and the last resort was a format. So i did that and reset the BIOS and im still in the same boat.You didn't mention that before. So you already have a new case and PSU? Maybe you should re-check your buildup first? Why did you move everything to a new case?

Event sequence (you CORRECT it as necessary)
1. WIRELESS USB keyboard & mouse stopped working.
2. Moved everything to new case and new PSU.
3. Wired USB keyboard & mouse stopped working.
4. Format HDD.
5. Reset BIOS
6. Reset BIOS, again.Has an OS been re-installed yet ? ?sounds like a loose connection
