What's broken? Power Supply, HDD, CPU, Motherboard... something else?

So a couple weeks ago I was updating my video card driver and in the process of rebooting the monitor said "out of range." After a few attempted restarts I was getting no display at all. Not even the BIOS.

I did a clear CMOS and I was able to see the boot up and the windows loading screen and then it would drop the display signal.

I took out my sound card, USB expansion card, and my video card. I've been connecting via the motherboard onboard video.

Nothing I did with Windows Troubleshooting solved my problem. I caved in and reformatted and reinstalled windows. Everything was going peachy. Windows updates were downloading and I went in the other room for a few minutes and came back to a blank screen. I rebooted and had similar issues to before.

I decided to reformat again. Again after 20 minutes or so the same issue struck.

It almost seemed this time like the screen went into hibernation and wouldn't come out as I was sitting there letting things download. I reformatted again and disabled the power saver that shuts down the display. This time i was browsing PC Partpicker and had only let the system sit idle downloading something for a minute or two when the signal cut out again.

The i5 3570K was previously overclocked to 4.5ghz. It is at stock since I cleared CMOS.

The motherboard is an ASRock z77 extreme motherboard.

There are 16GB of Kingston RAM installed.

The SSD is an older Samsung 120gb SSD.

Powersupply is 2 year old Corsair 750W modular Powersupply.

Given that everything runs fine through a system install I have a hard time believing the power supply is the fault. Temperatures in the room aren't causing an overheating problem either. I have the sides off my case and it is about 63 F ambient in the room.

With that said I feel like it could be anything i have absolutely no idea what to make of it. I would hate to do a partial rebuild of a motherboard/cpu/ram/ssd and find out the issue was my power supply. I don't have a good way to test the power supply though.

Any thoughts and speculation with reasoning for your speculation is welcome and appreciated.

I've tested that. It isn't the display. After a fresh install and 20 minutes of working every reboot it cuts out immediately after the windows loading screen.
