[jackysatio]

Helo guys..

after I build the system, I power up the pc, everything turn on, led , fan, water cooling using nzxt x62, but no display detected and mobo display code 4F.
I tried everything the forum and google guide, cmos, bios update using pendrive.
but no result, I tried using HDMI, display port on the monitor but still no display.

What code without RAM?

I just try to unplug both ram, and now code 53 when I power on. If I plug one ram at any slot, code 4f comes again. and theres 1 more thing, all the usb port isnt working, no led at mouse and keyboard

Turns out my CPU is dead. I tried other cpu everything works fine. Put in my cpu to another mobo, nothing works.
So conclusion if code 4F means CPU has something wrong.. cheers
