Title: GA Z77X-UD5H no POST only BBIOS and MBIOS LEDs blinking
Post by: dawees on June 07, 2016, 03:09:23 pm

I read similar topics here and i tried everything (cmon battery, different cpu, psu, ram). My PC yesterday works normally but the next day only bbios and mbios leds blinking... i dont understand why, its older mobo but still good for me. So my question: What to do? It can be repaired ?

Have you tried the memory in slots 1 & 2 instead of 3 & 4?

Have you try the Bios Switch? In the video it looks like it is set for the main bios. Plus it looks like for some reason it is jumping back and forth between the two bios.

Take it off the static bag it could be shorting out on it. I'm not really sure about them what they are made of.

All I can say try and pull the battery and jump out the cmos pins. Then leave over night to seen what happens. If it is still the same then the bios is bad. Or the CPU when bad.
