I have the pi-a9rx480 motherboard. I have tried both 3700+ and brand new 4000+ processor, several brands of memory, two different video cards, and the thing will not post. Actually, I got it to post for a brief moment, then once I turned off would not post again. I have tried clearing cmos. Like I said, it posted briefly, then would not post again. One other time posted after turning off and unplugging power supply. The board has some diagnostic LEDs on it, but I have not been able to find out what they mean. Any help please?

The motherboard is being tested outside the case. My power supply is 580 Watts, although I have tried others. I suspect bios corruption, if I could only get it to boot one more time I think I can force it to flash. So far, no go, including letting it set without cmos battery, jumper in clear position, and no psu attached overnight, still nothing. One thing I have noticed, however, is that the power led ( the one by the battery) goes off when i try to boot. The times I have been successful it flashes then goes on again. Does anyone know anything about the leds on this motherboard, or what that might mean?

GuruHi markpcfixer,
That green diagnostic LED you see on the motherboard is telling you there is power connected to the board. (That's all).
Each time you were able to reach post was from completely disconnecting power from the board. So I can suggest a couple of things. First make sure the board is not grounding through you're case. Is the board screwed onto the stand-offs? Stand-offs are copper looking legs that screw into the case. You lay the board over the copper pegs & screw down the board. Each screw should have a red fiber washer just under the screw so the screws do not short out the board. Nothing under the board should be touching the case other than the back plate.
Once you are sure everything is ok than make sure you added thermal grease between the CPU & heat-sink fan assembly.
Two things left. You're board needs a lot of power. Does you're current power supply include a 24-pin ATX main connector for
PWR2 J2800? (IF no you need a PSU that does). You also must have a 4-pin ATX_12v power connector on PWR1 J2802.
You're system will not boot with out these. You're board also can use up to 6 SATA drives. You're power supply should be no less than 500W. 550W would be better. If you are still unable to boot the system, only than would I consider flashing the bios. You can find that at this link. http://www.sapphiretech.com/us/support/drivers.php
You must pick the correct terms in each window to load the driver & bios page. They are (From left to right), Mainboard Soultions, than IGP Innovation- 780,690 & lastly,
PURE Innovation PI-A9RX480 Than click, Download the Driver
Each time you go there you will need to type this in.
You have swapped out the CPU & memory, the last thing to try is the power supply & bios. There is noting to check after that.
If I can help you further, feel free to post.
Suggestions & comments welcomed.

If the power LED dows go out when you start up the motherboard. You're board is bad. Return before it's too late. Very smart of you to test while out side of the case! You must have some experiance at this. When posting a question for help, everything no matter how minor it may seem does in fact help.
