Hey guys,
I basically was trying to find out why my bios couldn't sense one of my hard drives, when I accidentally unplugged it's cable then my whole pc suddenly when off, no display, no PSU fan running, no nothing.
Does this mean my motherboard is dead? If so is there a way to reverse(somehow put back the electric charges in the motherboard) the changes of my motherboard?
Thanks
