Hello,

I recently purchased a XPS 8940 i7 and when I would switch it on Windows 10 login screen would be on display in a matter of seconds. Felt pretty instant. Now, the boot up takes much longer and is very noticeable approx. 30 seconds. My 10 year old XPS 8000 even boots up quicker. 

Any ideas what may have caused this slow boot up?

Thanks
