Wow, no joke, I was about to make a new thread until I read yours. I'm having the same problem.
*There are times when my power supply is on, the LED on the mobo says power from the rail is being supplied to the 24pin, and when I press power to turn on the computer, it will turn on for < 1 second and then turn off. The LED next to the 24 pin goes out too.
*There are times when the above situation gives no problems at all when turning on the computer, but once I restart or shutdown, the LED next to the 24 pin goes out as well.
Honestly, I think this is one of mobo voltage more than anything. I like you, isolated my PSU and jumped it, having it connected to several fans and HDs, and it works okay. I have been running my Q6600 @ 3.6 at a Vcore of 1.4825 for about 1 1/2 years, and although it never gets close to getting above 65C, I can only imagine that my hardware is degrading from the wear and tear (games, stress tests, etc), so now it wants more voltage to compensate. I'll let the veterans chime in; just wanted to give me 2cents and let you know that you're not alone!!
