No logo, no bios. Power indicator, HDD and Caps Lock glow white. 3 years old. Nothing has been done to him. I took out the SSD and HDD and the problem is the same.
Someone to know ASUS led error codes.

Black probe on ground red prope on the gray square coils if you do not have voltage try while you pushing power button i write everyting on hd pictures. Program bios you must do with an external bios programmer. If you not have the tools or knowledge to fix your board i will suggest to go to a repair shop. For tools is recommend on good soldering station, hot air station , digital multimeter, bios programmer tool. This minium requirement to fix your board.
