Hello, I have a PC that I mounted with a motherboard Asrock X99 since more than one year.
And since a month, it randomly won't start up and show the error codes b0/19.


I have to clear the cmos with the battery method to allow it to start up. Then It boot correctly.

I currently have a P1.0 bios, and one day I tried to update the bios A from the SET UP, but after that the PC didn't boot windows (nor Linux). So I restored the bios from B to Bios A.

Is the motherboard defected ?

Have you any idea of the source of this problem ?

Thanks!
