So yesterday my pc crashed a few times, and this appears on my screen "checking media presence, start pxe over IPv4 and IPv6" after that my bios appears. Can get into windows, I put my hard drive as first in boost options but didn't work. Once I connect my old hard drive and everything worked out. Seems that hard drive is the problem... I tried swapping cables, unplug and plug everything but nothing seems to help. I wanted to take out bios battery but my mother board don't have it, don't know why. My motherboard is ms-b106 My desktop pc is Msi nightblade x2.
