Im pretty sure that my mobo ram slot 1 is defective, is this a rare or common problem? and if i replace it with the same model, do i have to reinstall drivers and windows?
Actually, I've never heard about this happening. But that doesn't mean it's not possible!! If it is defective, you can replace the motherboard with an identical model and you will not have to reinstall anything. (Because in theroy, you didn't change anything; you replaced "item 4" with another "item 4")
