So things are not so hot...

I tried overclocking my intel i73770k again (I did it about a year ago and it worked well, but had to change things for other reasons, hackintosh reasons). It SEEMED to work fine after reset, booted into Windows, but my CMStorm Trigger wouldn't start. I hooked up one of my Logitec keyboards, and I selected restart to see if I could fix the Trigger not starting. The pc displayed the power off screen, and then went blank as usual. The computer didn't power off, it stayed on, and I waited to see what would happen. My noctua fan started going into overdrive, and so I turned off the power supply. I started the computer again, and I heard a relay click in the power supply, the noctua started, and then powered off. It wouldn't respond at all subsequently. I proceeded to turn off the power supply for a good 20 sec, powered it on again, and computer would start for a second as before, and then power off. I pulled the clearcmos jumper and tried to power it up again. It did briefly, and I replaced the jumper. After that, now the power supply won't even start briefly. The mobo light is on for power, but that's it. No fans, no clicking, nothing. I don't know what the heck I messed up, and I may have fried my CPU. How shall I trouble shoot this? I can get my other desktop back from my friend, to TEST another power supply, but that's pretty much all I can do I think. How can I figure out what is wrong/fix it, short of buying another mobo or cpu to test if that's what it is? I have the following setup:

Windows 8.1 Pro
Asus z77 Sabertooth
Intel i7 3770k
Corsair AX850
Noctua NH-D14

Thanks for your help!

Cheers,
Mike

UPDATE:

I was misinformed as to how to clear the CMOS. I did it correctly as per Asus's instructions and now at least it powers on, for longer than it did before, before powering off. Also another good sign is that after it powers off, it powers back on, and then powers off again etc. Which is better than not powering on at all. Haha. But still no bios. Hmmm. Thoughts?Attempt minimal boot... 1 stick of RAM only, no HDD or optical drives connected, and see if you can get it to boot to bios or error out on you with info on the error.
I agree with DAVE's advice above, but also what settings did you change when you tried to overclock your CPU?  It's highly unlikely that you friend it unless you did something crazy but it's worth checking just in case, for example, you set the CPU voltage way too high.UPDATE: Ok, so the clear cmos jumper worked! I had detached all the cables to the psu before doing it, and had forgotten to plug in the power to the cpu. Dough! So boom, everything works! Problem solved. Now I just have to fiddle with things so I can dial in my OC so it doesn't freak out like it did initially.

I didn't fiddle with the voltages at all, just the turbo and a couple of settings in CPU power management as per an overclocking guide on TomsHardware. I'll just play around with the turbo setting and set the memory to XMP as I did before... Tha ks a buch guys!!!Hah, I think we've all done that at some point, glad to hear you figured it out.  If you need any help or advice with your OC just post back, though the Tom's guides are usually pretty good.
