We have built a new PC in the office and when we turn the machine on all the fans, DVD Drive, HDD all start up but nothing can be seen on the screen (stays in standby). Please note there is no onboard graphics.
M/B - GA-X79-UD3
CPU - Intel i7-3820
HDD - 60GB SSD
GPU - Gigabyte HD6850
any ideas on what this could be? I have reseated all hardware and when I remove the RAM i get short continuous beeps. If we have the RAM installed we dont get any beep codes.
