i think your memory may be fried. Have u installed more ram? i did this with my a4000 and the onboard sound were ****ed up and so were any i uploaded into it. However, any samples that i recorded into it worked fine. If u have installed more ram then u maybe weren't grounded properly and static may have ruined the ram. Then again, maybe u havent and this was a waste of our time. Good luck dude and remeber to use the force.
