thanks for the link alot of that came in handy but i still get the same messages

 

symtdi.sys--

Did you ntocie this in the error?

Uninstall the Norton products on your computer.

If that helps, and it should, reinstall them and see if the problem comes back. If it doesn't, then you are probably good to go, in regards to the blue screen error.

 

yes it in the message but i dont have any norton products

 

You do if that file is on your system.

Or used to.

Uninstalled any Norton products as of late?
