Disconnect everything from the Motherboard except
- keyboard
- mouse
- video output
- 20+4 powercable
- 4/8 pin 12v wire both coming from the powersupply,
- Cpu fan wire
- power and reset button to the case
- case speaker
The goal here is just to test the mobo:
If the computer still will not boot up the please remove the motherboard from the computer along with the power supply
place the motherboard on a piece of card board larger than the motherboard,
this will eliminate a short from the mobo to the case which could be a possibility
Install the cpu with, 1 stick ram in dimm 1, power supply, case switch and case speaker
Connect ps2 mouse and keyboard along with the monitor
Repeat the above and power on
If the computer now boots into bios you most likely had a case short so make sure when installing the motherboard in the case that you use standoffs,
and they line up with the mounting holes in the motherboard and none of the standoffs touch anything else on the underside of the board.

Have you tried testing the mobo outside of the case?
Disconnect everything from the Motherboard exceptNow you should have NOTHING connected to the motherboard except what was listed above.
- keyboard
- mouse
- video output
- 20+4 powercable
- 4/8 pin 12v wire both coming from the powersupply,
- Cpu fan wire
- power and reset button to the case

I have done all of this. I had it resting on a static bag instead of cardboard though, but same type of deal. I've tried different combinations as well. Like no ram, no video card. Also note that the CPU is not getting warm. I know the CPU is fine though, tested on a good motherboard. I am almost positive it's a bad mobo or incompatible CPU issue.

Accepted cpu's for that motherboard.CPU Type
Phenom II / Athlon II / Sempron 100 Series
AMD 140W CPU Support
Your cpu other then a 6 core fits within the parameters.

It's on the Asus website as a supported CPU as well, but only with a bios update. I just don't know for sure if it would not start at all without the bios update or if it would just run as a generic CPU without it.Accepted cpu's for that motherboard.CPU Type

If it doesn't boot at all then there is no way to change anything in the bios to get it to see a generic CPU.

Ok. I'm just not sure whether to buy the same motherboard again just in case it's a bad motherboard and hope it's not a compatibility issue, or buy a different motherboard. If it was because of needing a bios update, another solution would be to put a CPU in it that does work then upgrade the bios. It's all expensive ways to figure it out.If the bios update is required for it to identify the cpu correctly rhen it is changing some firmware to see the cpu correctly.

This may work but then you have a cpu you won't be using when you are done.another solution would be to put a CPU in it that does work then upgrade the bios.
