Good day! My computer is working fine , and during its operation is no problem , but when switched on, about three out of five cases , my monitor shows " no signal " . Thus the computer is always loaded and running ( audible sounds enter the system , you can connect to remote desctop ). After 1-2 reboots signal appears .

I tried all possible options which could find, I connected the other monitors, other cables to other video outputs . Pulled out and inserted again, the graphics card and RAM , tried to boot from a one memory stick , dropped the BIOS settings , took out the battery. Nothing helps .

The problem started after a successful update the BIOS to the latest updated version. I turned to the forum motherboard manufacturer , there is nothing but tried by me options I had not suggested .

The new version of the BIOS setup mode appeared "fast boot", I guess that the problem is like this , but I twisted these parameters in many different combinations and nothing helped .

Configuration of my PC :
GA-X79-UD3 (rev. 1.0) BIOS F20
NVIDIA GeForce GTX 670 (GV-N670OC-2GD bios F13)
i7 3820 + Deep Cool Shark
memory samsung 1600 , three strips of 4GB , set 1,2,3 slots
750W
SDD Vertex 4 + HDD WD Black 7200

sorry for my bad english
