It is a known problem for all dz77ga-70k at least many reported it including myself(corsair 500r)...still no bios update to fix this(hope we get it soon).Another solution someone mentioned is to remove the fast boot options and then the led doesn't blink anymore on the startup.
Reset your BIOS to defaults. Remove your CMOS battery, and unplug the PC for 45 minutes, then reset to defaults again and see if that clears it up.
Not true. Mine started flashing and Intel told me instructions I just gave and that resolved it.
yes that resolved until u do not set properly the bios and fast boot...if u set bios then blinking again, BIOS update is needed
strange... never came back for me... btw.. NEW bios released today! try it!!
