not sure how to explain it - but there are 2 brown squares with small black chips - attached to the card. one card doesn't work (the one that has the chips) which is the one i found to be causing my boot-less problem. the other card works, but does not have those chips in the brown squares - or holders - the computer is running fine - but video has lines all through it - i assume its those chips missing - and want to exchange them - but they don't seem to want to pop out without force - don't want to hurt them.
