Problem when installing two HP Compaq microphones

In fact I put my review on strips on the strips to the laptop. I think it can be retrieved.
For then I had no problems during my first purchase and installation of the bars on the 3 microphones HP Compaq which they were intended, I have a real problem I can not solve during the installation of the bars of this last command on two other microphones HP compaq strictly identical (barrettes recognized in the setup, but after validation and exit setup, no more display on PCs, BIP indicates no defective strips. micro frozen. It just have to turn it off by holding your finger on the switch.
But look more detail explanation of my first comment and tell me what to do.

Thank you in advance
