Computer beeps 6 times, flashes orange light 3 times,pauses,repeats

Hello,

remove the ram, put back one stick in the first slot , see if it boots. If it does, use the same method to check the other rams.

Then install in pairs. one pair ( positions according to manual ) , test . add a 2nd pair, test , and so on

@mazzinia_​  Still doesn't work, still beeps 6 times and orange light flashes 3 times and repeats.

@chirevam​ without ram installed , does it do the same ? ( as in same sequence of beeps and lights ) If yes , a dimm slot has some issue and you may try to see what happens installing one dimm in the others, trying moving it
