Hey guys, first of all, I wasn't sure if I should post this on the Motherboards or PSU section, but as I am not certain where the issue lies, I posted it on the MB section since there's a stronger chance it is BIOS related.

My specs:

2500K @ 4.5 GHz 1.37V (12 Hours P95 stable + 10 IBT passes)
MSI Z77A-GD65
8GB DDR3-1600 Corsair Vengeance (2x4GB)
EVGA GTX680 Superclocked
Crucial M4 SSD 128GB
WD 1TB Caviar Blue
Seasonic X-650 PSU

The PC is roughly 1 year old and I built it.

Problem is, and this has been ongoing since I built it, sometimes, when I turn on the PC, it will start booting and then power itself off, after that it turns itself back on and Windows 7 loads, exactly what happens when you apple new OC settings for example.

There is never more than 1 shutdown when this happens and it never happens when the PC is on and working, just during boot.

I ruled out heating issues, everything is well ventilated in my Corsair 650D case, all fans are working and the CPU temps are good (Using Zalman CNPS10X cooler)

I think we can also rule out any PSU issues since I recently tested my PC with P95 again after updating my BIOS for more than 12 hours and it was rock solid. I've also never had a shutdown during gaming since I got the PC.

My Overclock is raw, I have disabled, EuP 2013, C1E, EIST, Overspeed Protection, Intel C-State.

Is there any BIOS setting which could be causing this? I noticed that there's a setting under EuP 2013 called "Restore after AC Power Loss" and you can choose Power Off/Power On/Last State. But I think it only related to occasions where the PC gets shut down due to a power outage?

Which leaves me with the Power outlet. I am using an outlet splitter and currently there are 7 products connected to 1 socket:

1. PC
2. Yamaha RXV-471 Receiver
3. Morel Sub-8 Subwoofer
4. PS3 (Off 99% of the time)
5. Internet Modem/Router
6. TV Box
7. 42" LED TV Screen

The only thing I can think of is that maybe when booting up, not enough power is provided to the PSU and it turns off?

I have 1 other clear outlet next to the one being used and I'm fairly certain they both go to the same place in the panel because they are adjacent.

I can also try to replace the power cord, however, I replaced it once and I do recall it was happening prior to replacing the cord several months ago.

Any suggestions? Thanks
