No boot device available - please help

Hi, today my pc will not boot into Windows.

The black startup screen goes through a process showing Client Mac Addr, then after a minute or two says "No Bootname File Received". It then says "No Boot Device available" and offers options to press F1 or F2.

I go into setup via F2, and the two hard drives are showing as "Not present"

This pc has occasionally done this before, but then boots after a few attempts. Today it is determined not to boot. Does anyone have any ideas what is wrong or what I can try?

Thanks in advance for any help
