I had an old card 8400 gs. I sold it and with the money i bought a new card from ebay Geforce 220. The problem is when i insert the card in the slot and when i boot it will not boot only a black screen not even p.o.s.t. After that i with the card in but i connect the vga to the onboard still the same problem. Is the graphic card the problem or the pci e slot?
