My Pc restart instead of shutting down

Hello,
it is a week or so that I have a problem with my PC.
When I shut down the PC, instead of turning off, he restart.
Before restarting, for a brief moment I can see a BSOD screen, but I cannot read it.
After the PC restart, I see a small window telling me that the PC was restored due to an error.
The message detail is this :

A week and a half ago, I installed two add-on cards ( a PCI USB card and a PCIE USB 3.0 card), and with the PCI I has troubles to make it run, so I uninstalled it and I sent it back to the store.
With the USB 3.0 instead everything was fine.
I dont know if this is related to the problem I have right now.

Attached is the files requested on the BSOD Posting Instructions.

Any suggestion as what is the cause of this problem ?

Thank You very much !
Best Regards
