Hey guys, so I recently bought thing display card, (I've been using an on-board card from intel before ) and when I insert the card into the mother and power up, the comp wont boot, won't even go into the bios screen. But the card's fan and the mobo's fans are spinning. It does also have this beep code sequence which is 4-2-3-3 (extended block move) (don't know what that means though...)And when I remove the 5570 and use the on-board, even thing is fine. I'm sure that the card and the psu is fine cuz I try them on with another computer in the shop which I bought my card in. anyway, any suggestions and ideas? thanks. oh btw, I'm using vista home premium, lenovo a55-8706 so thanks guys... PLZ HELP!!
