I have just change my motherboard and CPU and adding a DDR3 2GB Ram. I notice that when I restart or shut down the computer and turn it back on, the computer will give 1 long beep and 1 short beep. Then I have to wait for at least 6 hours before the computer can boot properly again.
However, if I remove the graphic card, everything works fine even if I restart and shutdown multiple time. I bought my Graphic card for 2 month
This problem never happen with my old motherboard so I assume a motherboard problem.
Here is my computer Spec
CPU: AMD Athlon II
Board: ASUS M5A78L-M LX
Graphic: Sapphire Radeon HD6670
RAM: 2x 2GB DDR3
