Hi Komancere2013,
As you mentioned issue started after you installed some new software on the system, then you should perform system restore to an earlier point:

Also, if the issue still occurs then you should check the mouse and keyboard under safe mode:

Lastly, to isolate check this keyboard and mouse on a different system. Keep us posted with the results so we can advise you further.
