HD4850 no sound in 2 of my 5.1 system

I have a sr1650nx with 2gb ram a 550w psu and a sapphire hd4850. I everything running fine until i had to do a system wipe. After completely updating the system I installed the latest drivers for the psu and i lost all sound. Now that did happen before and all i did was install the realtek ac97 drivers and it fixed it. This time sound only comes from the rear and center speakers plus the sub, no sound from the side speakers. Any recommendations?
