Guys I have a problem: the PC (w7 64 bit) does not want to know to start, it loads the screen with the windows logo then turn off your monitor and restart (a few times instead of the monitor is off, I saw a BSOD). Restore tool startup (suggested by the same system in some reboots) failed to solve. I have no previous restore points saved. I tried to start it in Safe Mode but I did it only once, other attempts end up with a reboot after loading the files. That one time I was able to provisionally read something minidumb with bluscreenviewer and I remember that reported "Caused by driver: Raspptp.sys" and underneath was "Raspptp.sys + c0d5" Unfortunately, all the other items I do not remember. Do you know what is derived and above all how to solve?
