Random system freezing

Hi there, I recently just had some hardware issues with my computer. I'm on a new motherboard with a new CPU, PSU, and heatsink.

For some reason, whenever I'm doing something (almost always playing a video game), my computer will just freeze. The sound stops, the screen freezes, I can't make any more inputs, and nothing happens until I turn off my computer. Other than this happening, everything else is working great. I figured, okay, maybe I've got some bad RAM. I get a couple new sticks and swap them out and I'm still having the same issue.
I've even tried running HeavyLoad to push my CPU, memory, and GPU, and I was able to run at 100% for a few minutes without freezing. I'm at a loss here.

MOBO - ASUS 970 Pro Gaming/Aura
CPU - AMD FX-9590
GPU - GeForce GTX 970
RAM - Corsair Vengeance DDR3
PSU - Corsair RM 650i

Do you mean that you changed the CPU Bus Frequency from the default of 200MHz, down to 170MHz?

If you did this without changing anything else, it will downclock the processor to 4GHz (170 x 23.5). That number also affects your HT Link and CPU NB frequencies, as they are multipliers of the CPU Bus Frequency as well.

EDIT: This video is pretty good, it should at least show where everything is https://www.youtube.com/watch?v=MvhgH3bOW8A

The settings aren't too bad even, but every system is different so you can't just cut and paste

This is totally bizarre. I monitored my hardware's specs on a different screen with Open Hardware Monitor while I was playing games, and then it froze on me! I looked at the temperatures and voltages that were being reported, and they weren't nearly as high as the specs in the above picture.
I pull up the Event Viewer to see if anything else is going on, and I can plainly see the exact time my system started up again after rebooting, but there are no logs on anything for several minutes before the freeze.
I've got no idea what could possibly be going on anymore.

Do you think it could be related to my video card? It's about 3 years old. I don't have another power supply on hand, but do you think I should pick up another video card when I go to the store for the PSU?

It might be, but usually power supplies fail far more often than video cards. Over the way too many years I have been working with computers I have had maybe one video card failure compared to 10 or more power supplies. This includes more than one that was DOA.
I would inspect the video cards for obvious damage, like burnt marks, and failing components, like bulging or leaking capacitors.

Oh, god, I had some spare unused RAM lying around, so I replaced it. After that, it wouldn't boot Windows, throwing me an 0xc0000006 error and saying that I should try system repair. I wound up having to reinstall Windows 7 onto a different hard drive, and now my SSD isn't being detected. Interestingly, when setting up my drivers for the new install, it says that my SSD has the status of "Device unplugged". I hope my SSD hasn't died, too - this is basically a new computer at this point.
I guess I'll pick up an extra SATA cable along with the power supply. Just a heads up.

Well, after reinstalling Windows, I finally got a new power supply and swapped it out.
I still got a freeze when playing games. Any more help would be greatly appreciated, as all I can think at this point is that something is up with the video card.

Oh my god, I passed memtest AND got a new graphics card and put it into my computer. IT'S STILL HAPPENING! I'm losing my mind over here, what on earth is wrong with my computer? Is it the motherboard or something?

I can feel your pain, as this kind of thing has happened to me far too often. The only thing I can think of to test is try using the keyboard and mouse in different USB ports, preferably using the front ports if they were plugged into the back or vice versa. You can also try a different keyboard and mouse if you have them.
Maybe something in the device or one of the USB ports is causing your problem. I only mention this as your problems mainly happen when you are using them more in games.

Well, I actually just had a freeze while I was away from my computer for a few minutes. I just had my browser open.
And yes, this is after I tried different USB ports. I thought maybe it was a driver issue, so I downgraded to the version I was using before I reinstalled Windows, but that's not it either. My computer's normally plugged into those surge protectors that's also a battery, so I'm going to try plugging directly into the wall and see if that does it.
But it's weird that it happened to me when I wasn't even doing anything, though.

Hey, I think I'm on to something here! I forgot that while I was having the SSD issues, I was too worried about fixing it to actually test my HDD. I managed to play 40 minutes of Skyrim before getting bored on my HDD, while when I booted Windows from my SSD, it froze about two minutes in. I think my SSD is the issue here. I'll report back after some more testing.

I can only think of two things to try. If you place the SSD on the same port as your hard drive was on does it still happen? Is the game(s) you are having problems with on the hard drive or the SSD? If it is on the hard drive could you move it to the SSD to see if it still freezes?

I should specify further - The only thing that I use my SSD for is Windows, all of my games and such go into my HDD. When I boot Windows through the SSD (new or old) is when I start getting problems. I tried an old cable in a different port and that didn't work, but I haven't tried the cable that my hard drive is using yet. I'm still testing to make sure that the HDD really doesn't freeze randomly.

WOW, as soon as I made that post, I froze again! I was just on the HDD!
Jesus christ, this is maddening, I'm back at square one again!
I guess I should just swap the MOBO at this point, huh?

I am not sure if it would be cheaper to start with a new system or to see if a professional shop could find the real problem. The problem could be something in the motherboard or CPU. Or the problem could be that one of the parts you swapped out was also faulty. This has happened to me before and it is really annoying.
Just out of curiosity, have you tried running just on the SSD? Download a program like Heaven and let it run to see if it still freezes. This will at least eliminate a problem with the HDD causing your freezes.
