Hi

 

Turned on my laptop after the Christmas break it went on fine, i just got into outlook then the screen flashed black, I turned it off to start again and it just kept going blank, ran a diagnostic test and it came back with optimized DST failed.

 

What does this mean and what can I do to fix it?

 

Many thanks
