Hi, ill just get right to th ebasics. My motehrboard is a A8M2N-LA (NodusM3) with Phoenix Systems 3.07 Bios. It came with a AMD 4200 but i wanted to upgrade it to a 5600. I plugged everything in correctly and hooked up the computer. However, when i turn it on i hear the fans and everything but the screen is blanc, and i hear a repetative, long beep sound. I installed the old cpu (using it now) and everything booted fine. Can anyone explain to me why it is not booting up with the 5600 cpu and making a beep sound every 2 or so seconds? Thanks!
