2500k - Any kind of overclock, boot issues

I've tried a few times just doing a basic overclock on my i5 2500k, just upping the multiplier. Gigabyte Z77-D3H motherboard (had this issue on a previous motherboard though).

I've gone up to 4.7GHz, and many different clocks in between.

Every time, I do the overclock, and not had a single crash on any issue at all when stress testing and playing intensive games etc. All perfect.

The only issue is that even if I only overclock say to 4GHz, I've always had this boot issue whereby when powering on my computer it will 'fail' to boot several times, just switching itself off and on from anywhere between like 3 to 10 and beyond times, before finally booting.

Once I'm in it's fine, it's just this boot issue.

Any ideas?

I'd go through all BIOS options to see if everything is fine (like memory timings, voltages, disabling unused controllers etc). Newest BIOS is important as well. By the way, D3H series were troublematic, maybe it's that case.
Which PSU do you have ?
 
I used to have an intermittent boot issue very similar to what you describe. Eventually it refused to boot completely and it turned out to be the graphics card. Worth looking into if you have a spare to test with. It was always on a cold boot. Since changing card it's been faultless.
 
Potential Breakthrough! (kind of)

So I just had a go at setting the the XMP profile for the memory on, just as a test, was previously Disabled and tried setting it to the only other option which was 'Profile1'.

Save and exit, booted into windows, then shut it down to try and do a full boot.

And.. same boot loop!

That being tries to start up, fans start going, then shut down. Then starts up again, goes to a blank Dual-BIOS screen, then shuts down. And repeat cycle.

So, does overclocking the CPU affect the memory in any way? Because if I OC the CPU, I get this boot loop problem. And if I try the XMP setting, with the CPU still at default settings (which have never caused an issue) I get the exact same problem.
