I brought most of the parts to build pc. This is what I brought

Mobo - evga z370 matx
cpu - i5-8600k
gpu - evga 1070 sc
psu - corsair tx750m
hdd - wd blue 1tb
ssd - samsung 860 evo
ram - gskill ripjaws ddr4-2400
case: some oem matx case

so i put everything together and bios 1 gives error code 23, which is not even in the manual, bios 2 gives code 99.
