Just received my rev 3 p67 board and have been in the process of getting the my machine up and running again. Here are the build details:
■Case: HAF922
■PSU: CoolerMaster Silent Pro M 700w
■Mobo: Asus P867Pro Rev3
■CPU: Intel Core i5 2500K
■Memory: Corsair XMS 8 GB (2 Dimms)
■HDD: WD 1TB Caviar Blue (to be swapped for SATA 6gb/s when next gen comes out)
■Optical: Lite-on BRD Drive
I purchased the system at the end of January. After build everything worked perfectly and the system worked like a dream. One day after about a month of solid use, the machine no longer was passing POST. All I got was a bright red CPU LED lit up.
Attempting to fix it, I first laid it on it's side and hit the power. Booted fine...the first time. Subsequent boots however failed. Because my RMA mobo was on it's way, I decided to just leave it be for the time being since I was going to have to take it apart anyhow.
Rev3 board comes in. I take out the old one and pop in the new. Boot the machine, doesn't past POST - same CPU LED. Frustrated I leave it for a week. Coming back to it, I again put it on its side and boot, this time it works. Odd. Try again, same thing. Stand it up...no POST success.
At this point I think it's a short. The Mobo is new, so i figure it's not that given the behavior is identical. Hypothesis at this point: perhaps it's the case or something that's touching something else and causing it to short.
So I pop out the mobo, put it onto some anti static wrapping with the memory, cpu, and case front panel LEDs and switches attached. No Good. So I remove all the case front plate connections aside from the pwr swtich. It boots! I try it a number of times and it seems solid.
Put the mobo back in the case and try. Success! At this point I feel pretty confident and start plugging things in one at a time to test and see if it passes POST. Nearly everytime I plug something new in it fails. But trying again immediately after we seem okay and it passes post.
At this point I have fans, cpu, memory, and all front case things plugged in directly (not through the Q-connector thing Asus provides). Next I try to plug in the HDD and Blu-ray drive. Fails. Try again. Start. Try a third time to be safe. Fails. Unplug HDD and BRD drive. Plug in GPU. Success! Again. Fail. Success. Fail. Fail. Sixth boot CPU LED blinks and then goes off, but this time it hangs on the DRAM LED.
After a number of more boots, it seems to boot every third time. For giggles I plug in HDD and BRD Drive again. Boots 1 in 10 times, and 1 in 5 times it hangs at the DRAM LED and not the CPU LED. Tried this about 20 times until it seemed to never boot.
I have only a single guess at this point, and am looking for some advice. My guess is that it is the PSU. Why? The only pattern I've noticed is:
-When it boots, the CPU fan speed seems lower
-The more things plugged in, the lower the likelihood that it boots
Anyhow, any help would be greatly appreciated - thanks all!
