Ya I'm pretty much out of ideas. Hopefully a new windows will work. What version of BIOS are you running?? The reason I ask is you don't have any profiles set up yet for the 8350 so a bios flash wouldn't be erasing anything at this point. I would just hate to see you go through a re-install and not fix the problem. Follow me ? I know from experience that an old bios can do weird things when swapping parts around. I f you do decide to flash it make sure to clear the CMOS after. Gives it a good fresh start and is necessary.
