so i bought a new hp computer ( m8400f ). i succesfully replaced the power supply with a corsair 650W psu. and then i tried to install my new evga 9800 gtx+ superclocked version when i came across a problem. i believe my motherboard is an nforce 430, and the sata data cables going into the motherboard are not allowing my to connect the graphics card. when i unplug the 3 sata data cables (2 harddrives and dvd) from the motherboard the card fits just fine. but im pretty sure those need to be connected.. so i have no idea what to do to solve my problem. please help me.
