PC won't boot into Windows after any change in voltage

I recently bought an i5 4690k and am trying to overclock. I've gotten to 4.2 Ghz at stock voltage. However, any time that I attempt to manually change the voltages to my cpu's cores, the computer will not boot into Windows and I get the "whea uncorrectable error" in a never-ending loop, forcing me to go back into the bios and set it back to "auto." I am wondering what is holding me back from being able to change the voltage. Simply increasing it by .001 v makes me get this error. My other specs are as follows:

ASUS Gryphon z97 mATX motherboard
8 gb (4x2 gb) adata 1600mhz @ 1.5v
gtx 780
corsair ssd
western digital hdd
dvd drive
Corsair gs700 PSU

Any help/feedback would be greatly appreciated. Thanks!

I think its because if your power supply , when PC is starting up , parts lure their max tdp as you have Gtx 780 eating a lot of power , and u are already over clocking , motherboard can't provide sufficient power to the components and it could be anything ( ram , HDD ) that stops the PC from booting to windows and my suggestion would be don't increase the volt ,just increase the frequency as much as you can

What is the voltage at normally?
When you change the voltage, what does the temp say in the BIOS?
Why are you changing the voltages? even while overclocking, 90% of the time you don't need to change the voltage unless it is by an extreme jump.

the voltage is normally at 1.008v
the temps in bios after i change the voltage are around 31 degrees. changing the voltage is often required when overclocking to achieve stability at higher frequencies. Like I said, I can't push my frequency higher because I think that i need to increase the voltage.

I was also thinking that it may be the power supply. I did manage to get to 4.5 ghz without changing the voltage, though. I monitor voltage and temps and that kind of thing with hwinfo, and it seems to change when I need it, depending on cpu load. It will even go past stock 1.008 to higher volts like 1.2 on it's own.

Let's go deep
As you are saying that 1.2 volt , I had a little thought and found the answer
Now read on , when you set the voltage to auto that means you are giving the authority to the mobo to control the voltage , now how does the mobo automate the voltage from the PSU? Let me tell you , now your PC component does not draw power all the time , when your Gtx 780 is not consuming enough power in a CPU oriented game ( let's take a game eg.) Then Ur CPU tries to lure power as much as it needs or vice versa , same goes for other components , now as other components are not as power hungry as CPU and GPU they does not matter to the mobo , now the verdict here is that mobo switches the voltage from 1.008 to 1.2 as it needs on its own and when u set it manually u know the rest
And sorry if I have gone too long with my explanation

Yes, I've achieved 4.5 ghz on auto.

I can't recommend any solutions. You may just want to settle for 4.5 and be happy with that.

I can't really complain about 4.5, that's a pretty decent overclock imo. I'm just curious about why I can't change the voltage at all.

Your latest bios may not support voltage change , u shouldn't have changed the bios version

Lol I've never heard anyone say to not update the bios. But either way, it did this on stock as well. So it isn't a bios version issue.

Well I'm not sure what you are suggesting because first you told me to update the bios, then you told me I shouldn't have done it, and now you're telling me to update it again lol. I'm gonna have to disagree, I don't think it's a bios version problem.
