Trouble booting the OS. PSU to be suspect?

I recently finished putting together my system and have been encountering a problem that causes my computer to only boot the OS intermittently. When it does boot it has very noticeable graphical problems like mouse and window ghost trails. It also will not manage to get through the driver installation process as it requires auto restarts that often fail. When it does not boot it goes to a blank command prompt-ish screen, but the keyboard is unresponsive or it will just send no signal and the monitor turns off. The computer just stays on until I manually shut it off. I have clean installed Windows 3-4 times and had the same results. I posted about this problem before and the only answer I got was that the PSU was junk that would be a better door stop. I don't know that I'm convinced of that because I'm running a 95W 7850K with no graphics card. Even though my PSU only has 20A on the 12V rail it should be enough, right? Anyhow, here's my specs:

ASRock Fatal1ty FM2A88X+

AMD 7850K

Toshiba Q Series 128G SSD

LG CD/DVD-RW Drive

6 gigs G. Skill 1333 (3x2g)

RAIDMAX Hybrid II RX-530SS 530W PSU

Running Windows 7 Ultimate 64-bit

It's also powering 5 120mm fans aside from the CPU cooler

So, I replaced the PSU. Changed to a Corsair CX430M. I'm running a clean install as I type this, but on the first reboot after installing the new PSU I had the same symptoms. Intermittent boots and sometimes just getting a black screen with a blinking command prompt or the monitor just receives no signal. I honestly don't think that my power supply was ever the problem, it may have been a brand that has had poor customer feedback, but it was functioning and well within my amperage and wattage needs. While I am glad to have installed a nicer, more modular PSU I am a little disappointed that the only answer I got was to get rid of my PSU.

I have no idea how to fix the issue, but it might help to change the title or start a new thread.

Only thing I can think of is taking a look to see if there are any motherboard bios updates available. I only have windows 7 home edition since it came with my computer so I have no idea about ultimate. There are also hard drive tests but I am not familiar with those.

I have more than one computer so I just swap out components to see what item is the culprit with the exception of the processor and motherboard.
