Hi, New Here. I incorrectly fitted my fan onto the north bridge fan port . This cause my computer to shut down. Since then it now will not restart and system hangs on 3.7. on the guru counter. I have tried different mobo(av8), power supply, disconnected everything i can and problem still there . Could it be processor. Ahhhhh. What will this mobo take up to as AMD now do Athlon 64 X2 5200+. On AMD website It only specifys Upto 4800 ???. Thanks
