Getting beeps on first run despite every try

I have built a new pc. I connected everything and when booting it I am getting short continuous beeps.It starts, all the fans runs perfectly, I can hear the hdd fan too.
I have been searching for solutions various forums now and trying those solution, still couldn't figure it out. I have tried Unplugging- Plugging RAM, buying new RAM, making the computer static free by starting all over, applying thermal paste again to make sure it is not over heating and also did wire management again to make sure no wire is causing static current.
My configs are:
Mother Board: FM2A88X Extreme4+
CPU: AMD Athlon X4
Power Supply: AeroCool 550w
