I did a bit of googling around the ' npsvctrig ' you mentioned . It looks like other people have had this issue too . If you open the Control Panel and go to System , then Advanced System Settings on the left , then Startup and Recovery settings button at the bottom , there will be a checkbox to disable automatically restarting . If you do that , try leaving your system on for an extended period and see if the reboots stop . Additionally , since the issues seem to have something to do with the file system , you may want to run a HDD diagnostic tool . <| sep |> Is this DDR 4 or DDR 3 ? <| sep |> uSpez I thought you were one of the good guys <| sep |> I agree , If I were a security personnel at a concert , I ' d be standing right next to the lead man the whole time , so I don ' t have to waste time running from the backstage to tackle a guy .
