My computer isn’t picking up my mouse and keyboard

[Gaines24]

Okay, so here’s my issue. I have a Razer Blackwidow keyboard & razer naga chroma, one day when I turned my pc on the side buttons on my mouse weren’t working. After doing minimal research, I uninstalled the keyboard and mice from the device manager. I restarted my computer, plugged the devices back in and my pc didn’t detect them. I switched the ports, 2.0, 3.0, everything. After it wasn’t picking up, and I couldn’t sign in to reinstall the drivers, I switched to a different mouse/ keyboard just to sign in and fix my problem but the same thing happened. The mouse would flash on but if wouldnt move. I can’t open the Bios or log in because I have no input. I’m currently using windows 8. Please help! Thank you.
