my dell dimension 9100 motherboard is short circuiting, so i need a new one. (don't know how to test it) becuase it cuts off in less then two seconds. so i want to upgrade the motherboard. it/s a sata harddrive that have all my info onto it.
I was thinking about atx(?).
where can i get a good deal on the motherboard? and/if can i upgrade it? :
