hey guys I know I have made serval posts today, after reading the manual, I reinstalled the memory on slot A2 and B2 as it said in the manual, after doing so I get no video out put, and I will get a contusions fan noise. so I want back to channel a1 and a2 and everything boots, fine and reads 16gb, anyone have a clue why its not booting when I put it in A2 and B2 as the manual says,
