Computer randomly freezes every day or so, requires hard reboot.

I've had my computer for three years now, built back in December 2015. Issue started around December 2017.

What is the issue:
My desktop completely locks up. No input seems to work, all three of my monitor's images freeze, numlock light won't toggle on the keyboard, and it's RGB lighting resets to it's default red that it does when the Corsair Utility Engine is not loaded yet. Computer's fans (CPU, GPU, power supply, two case fans) are all on, and so is a blue light on my motherboard. I can also feel parts moving inside my two hard drives (Can't check that with my SSD as you can't feel anything move inside it). Computer's OS is definitely frozen/off, because my friend has told me that I'm not still on a Discord call with them as the freeze happens.

Computer requires me to either hit the restart button or hold the power button to shut it off, and then push it to turn it on.


My computer specs:

OS: Windows 10 Home (Both OSs are that.)
CPU: AMD FX-6300
RAM: 8 GB (2x4GB Corsair brand)
GPU: PNY GeForce GTX 1050 Ti XLR8
PSU: 400 watts? (I don't know anything about this PSU, it came with the case.)
HDD: 2 Hard Drives (One is my old OS drive that is 500 GB, other is a drive I use for storing video games and videos which is 1TB)
SSD: 1 Corsair SSD (500 GB big (Not the same as my 500 GB HDD, just to clerify))
Monitors: 3 of them. Two are 1080p, one is 768p.


When did this start:

I originally wanted to clone my HDD OS to my SSD and run Windows from that, but that proved problematic as the cloning process didn't work, so I managed to get a Windows 10 Boot thing onto a USB drive and installed a brand new Windows 10 onto the SSD (With the old OS HDD unplugged during the install as I've heard that causes issues.) It worked successfully, and so I've kept my old OS HDD and my 1TB hard drive plugged in afterwards as I like to have access to all of my data.

Everything has worked swell, but only a short amount of time after that (I don't remember specifically) my computer suddenly did as described above in the 'What is the issue' section. At first I dismissed it, but once it started happening every 1-2 days, I knew there was an issue at hand. It's seemingly random with how it happens, sometimes it happens once per day, sometimes it happens once every 2 or 3 days, it's random but never takes longer than around 4 days. It can happen if I'm playing a video game or just browsing the internet, looking at files on my computer. It seems to happen regardless of what I'm doing.


What I've tried to fix it:

Reinstalling the graphic drivers.

Uninstalling some programs that I thought could be a culprit (MSI Afterburner, Corsair Utility Engine, seems unlikely that it's a software issue though).

Turning off and on cache writing to drives.

Going into device manager and hitting "Update driver" on every single option.

Doing Memory Diagnostics Test for my RAM.

Right clicking on each drive and checking for disk errors.

Switching SATA modes (From IDE to AHCI. Old OS HDD uses IDE, SSD OS originally was IDE, but I've not only tried switching to AHCI but also reinstalled Windows with it being AHCI to begin with).

Updating BIOS (There is no new BIOS version to update to).

Running the SSD OS with the old OS HDD unplugged.
Running the old OS HDD with the SSD OS unplugged.

Switching GPUs.

Overheating is not an issue, as it seems to freeze regardless of how hot my CPU or GPU gets. My drives temps are always fine whenever I check them.

Also tried looking at Windows Event Viewer, nothing seems to be there of interest. Just mentions loss of power, that's about it.



What I think could be the issue:

Judging from everything that's happened thus far, I'm assuming it must be a hardware issue but that's hard to figure out from this point. Could it be my motherboard, power supply, or somehow CPU? Power supply was my first guess, but if the computer is still being powered during the freezing then is it really the problem? I'm not sure because I don't really know much about power supplies, so that's why I wanted to come here.

I have no way of replacing the power supply, motherboard, or CPU as I do not have the money right now to replace any of them, which presents a huge problem as I can't just replace each component to find out what is the issue.

If anybody has any ideas as to what it could be, please help me. I've tried so many things to try and fix it and it's just irritating the crap out of me.
 
Test it with a single stick of RAM, alternately to test both sticks...

Borrow a known good quality PSU of sufficient wattage....

COnfirm your temps are OK...

Remove side of case, and blow small fan across motherboard's VRM circuitry to see if stability improves...

Thank you so much PupurHacker, resetting my BIOS settings to “optimized defaults”, turning off the ability for the computer to shut off the internet adapter for saving power and turning my power plan to maximum performance has fixed it! It’s now been more than a week and it has it hasn’t frozen once, thank you so much!
