The screen (freezes) then after about a minute it cuts to a blue screen and gives me an error message: DPC_WATCHDOG_VIOLATION.

 


 
This happens absolutely randomly, but not so often - can only once a day or several times per day. Has some cases , everytime  PC restarts after the BSOD, the Realtek Audio Drivers go missing, and there is no sound coming from the PC, as well as the audio device being hidden in device manager.  However, after a hard power off (holding the power button) the Realtek drivers comeback. This error occurs not only on old computers, but also on newly purchased computers. It would be really bad to be in this situation.

Step 4: Click the Scan for affected programs button to confirm the apps that will be removed because they were added after creating the restore point.
Step 5: Click the Close button, and then the Next button. Finished

 

Once you complete the steps, System Restore will apply the restore point returning the computer to the previous good working state. If one or more apps were affected, remember to reinstall them again after the recovery process.

You can remove the hardware (usb, mouse, keyboard, wifi, bluetooth card...) to check what could be the cause?.
