Default Flummoxed by problems with new overclocked build

So I got an asus z77-lk and i5 3750 and overclocked it to 4.4 ghz for about a month and a half stably with games and 24/7 load with BOINC. Just recently, it started resetting, and when it came back up it paused after post saying "Power Supply Surges detected during the previous power on. ASUS Anti-Surge was triggered to protect system from unstable power supply unit!"
I reset the bios back to factory and for some reason my computer is still at 4.4 ghz? I turned of Intel turbo boost and then it goes back to 3.4 ghz, but still has the resetting issue. I turned off the ASUS anti surge setting in bios, since I'm running with a nice big rackmounted ups, and my psu is a new rosewill CAPSTONE-750-M. I have an old 520 corsair that I guess I could try swapping out.

1. So if it doesn't happen know that I turned of power protect am I ok?
2. How can I try lowering the overclock to say 4.2ghz since even the factory reset didn't? I tried manually setting a maximum multiplier of 42 and a factory reset, but it still went up to 4.4 ghz.
3. I guess I really should try another psu? It can't be that my ups died right?

I would look at those modular psu connections.
I am looking for a cheap upgrade to my 3 year old computer.

Wow! Thanks, that was it man! It stopped working completely; one of the cables had wiggled loose somehow, but it seems to be fine now that its in. Now I'll just have to overclock it again since I took out the battery and reset everything again. We'll see if I have the same weird 4.4ghz issue.

I would go with the old psu you have to check to see if the problem disappears. When it does, as long as the 520 has enough power to run your system - probably at stock - then invest in a real power supply. The rosewill power supplies are not what I'd call dependable. It's usually not the amount of power but the quality and stability of the power that makes a HUGE difference. Go with seasonic, corsair or antec would be my recommendation. And oh, if your power supply seems to be causing problems take it out of the loop quickly, it will probably take out other components before it actually goes up in smoke.
