Inventive title! :P

I've overclocked my q9550 to 3.4GHZ but it takes the computer like two start ups to actually boot up. First time everything clicks on and you can hear it all happening, second letter it all clicks off like shut down and then immediately starts back up again.
Any reason for this?

I'm also looking at getting a PCI fan controller to try and help the noise, is the bay just the best place for them? I can't see them in the OCuk store.
 
My systems in the past have done this, check for any updated BIOS revisions, I think the boards starts up, applies the overclock then restarts.

On my current system and my old i7 920 system you can here several clicks before the machine boots with the post beep.
 
My Asus P5K-E used to do that. It makes a cold boot slower but otherwise it was never a problem for me.

I had standard CPU clocks but the RAM needed a faster ratio and more voltage.
 
Sounds like a cold boot issue. As RJC said, look for BIOS updates.

When it boots the 2nd time, does it keep the overclock or come up with an OC fail message?
 
I remember my old P5K PRO used to boot up, fans would all spin at max then it would reboot and start up. I was informed this was normal so i left it alone.
 
If you turn the power off at the mains when you switch off the PC that could be what causes it. My friends system did the same thing but only because he always turned the power off at the switch.
 
Try give the vcore a tiny bump. If you don't have this problem with stock clock, then the chances are it ain't cold boot, but just a bad overclock as already mentioned.

Did you actually stress test the CPU to check for stablilty after you overclock? Being able to boot into just the Windows desktop alone doesn't make it a stable overclock.
 
Mine does that also if I overclock it to 4.2ghz otherwise its completely stable. So I have set it back to 4ghz atm which it doesn't do it at until I work out why. I assumed it was the cold boot issue which I assumed had no cure as I'm running latest BIOS?
 
Loading once, then turning off, then loading again is a standard self-test feature on some motherboards when an overclock has been applied. If it keeps the overclock, then everything is fine and dandy :)
