Abit av8 bios post codes 8.3 - 8.6 - 9.c What is failing on boot ? I get one long beep followed by 4 short beeps. I have swapped video cards and reflashed the bios with no help. If I reboot 2 or 3 times the computer will eventually boot.

I still did not find beep code that match your problem..

Anyways here are the common beep codes for your motherboard.. it might help you too.
1. No beep - no reaction, the mother board is dead, power supply problem, processor and or ram problem.
2. 1beep - board is working fine.
3. One long beep then it shuts down - cpu problem, your processor is not working or missing.
4. 1short beep - system boots normally
5. 2short beeps - CMOS setting error.
6. 1long 1short beep - dram error
7. 1long 2 short beep - video card or monitor not connected
8. 1long 3 short beep - keyboard error.
9. 1long 9short beep - ROM error
10. Long beep - memory card is missing or not connected

12 Four beeps - there is no fan detected on Fan1 or Fan2 header. make sure to attach or reset CMOS bios to factory setting.
