I have an old m2n68la narra 2 that came with a athlon 64x2 4400+ and I tried to install a Phenom x4 9600 .When I turn on the computer I get a black screen,nothing from the graphics card port or the original vga work. I tried resetting the cmos and the bios is updated to Phoenix tech 5.13 but still nothing is working. I'm almost 100percent sure that is a compatible CPU but I am fairly new to computer repair.any ideas to get it to work?thanks,jack
