Computer freezes randomly, no sound, hard reset required. Not PSU, temp, or RAM

[Onlooker38]

I am having completely random freezes to my desktop. The screen will freeze in place, sound cuts from speakers, and it requires a hard restart in order to end it. The freeze is so random I have no idea how to pin down the problem. I could be playing games for hours and then freeze, I could be watching Netflix, or working on Word documents and the computer will FREEZE. Sometimes it runs for a day and then freezes three times in one hour. It seems like the only time it runs fine is when the computer is completely idle.

Recently the computer froze and I performed a restart. The system got caught in a restart loop and i had to hold the power and shut the system down. after booting it has worked normally, but it is only a matter of time before it freezes again.

Here are the fixes I have done. Nothing has worked:
Replaced ATNG 600W PSU with a Corsair RM1000X 1000W PSU ... no change
Tested CPU and GPU temps with SpeedFan. Everything runs under 60C even at full load (Fallout 4 on Ultra)
Memtest86 for 4 passes on 16GB with no errors.
Reduced the speed of RAM from 2133-1600 MHZ ... nothing.
Installed new drivers into GPU. Nothing
Disabled Turbo overclock mode. Still nothing.

Here are the specs:
CPU :AMD FX-8370 4.0GhZ
Motherboard: Gigabyte Technology Co. Ltd. 970A-DS3P
GPU: 2047MB NVIDIA GeForce GTX 950 (Gigabyte)
SSD: 111GB SanDisk SD8SBBU120G1122 (SSD)
HD: 931GB TOSHIBA DT01ACA100 (SATA)
RAM: 16.0GB Dual-Channel DDR3 @ 2133 MHz
PSU: Corsair RM1000x

So now I am extremely frustrated and completely out of ideas. I'm not a hardcore gamer, and I don't overclock the system. I like to play games, but the majority of my time is used on Adobe Illustrator, MicrosoftWord, PowerPoint and Excel. I have lost a LOT of data and I now auto-save every ten seconds to keep things safe.

My computer knowledge is not that great, and it has been a learn as I go kind of process. So please take that into account if you have any solutions.

Thank you for the help!

I had a similar problem once. You can try to set your CPU ratio lower in BIOS. I had the fx6100 and i set the ratio to 15x so it was clocked on 3000mhz instead of 3300 and it worked for me. Just give it a try also disable amd cool n quiet

When did it start to happen? Was it from the start or happened suddenly?

some more things you can try.
BIOS update
complete system drivers update
HDD check with brand specific tools
disable PCI express power saver (under the advanced settings in power management).
clean install windows

Computer freezes can be nasty they can happen for numerous reasons.

I wanted to wait a bit before replying. So far about 48 hours later I have not had a single freeze or hard reset. I set the CPU at 3.4 MHz instead of 4 and disabled the cool and quiet feature. Kinda crazy but I think some of my games are running a bit more smoothly. I got no idea why this works. All I can say is thank you!
