Hi,
I have a Dell XPS13 ultrabook which when I power it up the dell logo flashes then nothing, then f12 Boot options on bottom of the screen if I touch a button, I can get into setup and have done a full Diagnostics and everything checks out ok, I got this computer on 25th feb this year, it was delivered to a gut in the states on 19th feb this year & I bought it off him, any ideas?????
