Random things going on

Ok, so I have no idea what is going on. I rearranged my living room and disconnected everything last night. I put everything back together, and now my computer is doing random things. When I have FB pulled up, i try to open chat boxes, they close automatically, and letters randomly get typed and sent, etc. I have scanned my PC with Malwarebytes & Superantispyware. . Nothing detected. So, I don't have a virus or anything of that nature. What's going on? I don't think my computer is being hacked or anything, but I don't know for sure.

Note: This all started when I connected a brand new keyboard. I did not have any problems with the old keyboard. This new keyboard was factory sealed too.

Disconnect your entire PC (and peripherals, if any) from the AC. Is your new keyboard (and mouse) wireless?
If so remove the batteries from both, wait 10 seconds and reinstall them. Move the little wireless receiver to another USB port.

Then connect everything to the AC and power up the PC last.

Let me know. There might be another step.

Thanks.

I did all of that. I have determined that if was the new keyboard. I bought the Microsoft Ergonomic Keyboard 4000 v1 from someone. After installing the drivers for Win10 x64, it still will not work. Now, I have the SAME keyboard on another computer from best buy, only I do believe this is v2, so that tells me that v1 is not compatible no matter what. I have not had any problems since reconnecting my original keyboard.
