Highly unusual flickering lights.

The fan control lights on my NZXT Phantom case randomly started flickering and making sounds. This has never happened before, and seems to have just started today after I attempted to raise my 4.2 OC to a 4.3

I've since taken my OC back down to 4.2 but that hasn't stopped the issue, and it seems to be directly related to whether or not the fan on the top of my case is spinning or not.

I cannot imagine that this is in any way good for my computer, but I have no idea what the cause is.

These are the risks you take when you start messing with your computer.

Did you change the voltages on your system for the OC?

No, I didn't. The OC worked fine on the old voltage I had, unless for some reason my voltage changed automatically and I didn't know about it. Do you think it might be too high?

You never said what your CPU is, but I am guessing you overclocked it once before, right? How did you do this? Some BIOS settings make all the necessary adjustments for you, including voltage. I would research exactly what was done to get to 4.3GHz.

Sadly, stuff like this can be hard to diagnose. Hopefully you get lucky by setting everything back to the very original settings (not your 4.2GHz overclock)

My CPU is an i7 3770K with an ASUS P8Z77-V LK mobo. I've OCed before on this system, to do it this time I simply bumped the CPU ratio up from 4.2 to 4.3, but I guess it's time to dig into it and clear the Cmos.

On the off chance that doesn't fix it, what would you recommend I do next?

Looks like to me you lost A leg on your power supply. What was the brand and wattage of the power supply.

SeaSonic 620W

Have you tried turning off the power supply and unplugging it from the wall for a few min to let the system drain??

I haven't, but I'll try that before I clear the Cmos.

 

[Setsukai]

I've tried turning the power supply off and letting the system drain, then I tried clearing the Cmos. Neither of those fixed the problem.

Again, it only happens when my top fan is spinning, but aside from that I don't know what could be causing the problem.

It could be that the top fan went bad.when it running it pulling to much juice through the fan controller on the Case. Try fowollimg the fan power leads and see if the case runs fine with it unplugged.
