Restarting or shutting down (power off)?
There should (could) have a possibility of disabling automatic restart (the just reboots again behavior).
By disabling the automatically restart on system failure feature, you are able to read what messages appear on the blue screen and can, if necessary, pass the information on to your technical support person or post here.
It's important the error numbers and the error message there.
Do you have any other antivirus installed in this computer?
Which firewall are you using?
Disable Automatic Restart:
Using Registry Editor:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
DWORD = AutoReboot
0 = Auto Restart Disabled
1 = Auto Restart Enabled
Not using Registry Editor:
System Properties > Advanced > [Startup and Recovery]Settings
Remove the checkmark from "Automatically Restart" in the System Failure section.
