Instability and Hard Freeze During Gaming and During Prime 95 Blend Test (Hard reset required)

I have recently built a new computer and I am having a reoccurring issue with a hard freezing of my system. I cannot alt+F4 out of programs, cannot open task manager or alt+tab when it happens. A hard reset is required to get my computer out of the freeze.

I have been able to recreate the issue with Prime 95's blend test, it runs just fine on the other two tests (Small FFTs and In Place Large FFTs).

So far its either my PSU not being able to handle it, my RAM is faulty and craps out when under heavy load, a corrupted Windows 10 (somehow), or my CPU is overheating (Not exactly likely because it handles the heat torture test fine). I know you're "supposed to" have a water cooler set up with my CPU but it really shouldn't be an issue and I would like to avoid water cooling if at all possible.

Here's my specs:

OS: Windows 10 Home
CPU: AMD FX 9590
Cooler: Cooler Master Hyper D92
Motherboard: Gigabyte 990FXA-UD3 R5
RAM: 2x8GB Ballistix DDR3 1600mhz 1.5V
GPU: Radeon RX480 MSI Armor 8GB OC
PSU: Rosewill 650w Hive 80+Bronze
SSD: Kingston 120GB
HDD: Hitachi 2TB
Case: Fractal Define R5
After market fans (2):Rosewill Hyperborea 14cm

*I have 4 case fans installed, I moved the stock case fans to the front and the after market fans are set up as close to the CPU as possible. Pulls air from the front and pushes it out the top rear corner.

Doing a RAM swap with my buddy to see if that's the issue I'll also try his PSU. If that fails I'm going to reinstall windows. The Bios is up to date. Could be the CPU, lots of forums are saying its a volcano and its power heavy but really it would be causing issues during the heat stress test (it doesn't) instead its during the Blend test on Prime 95. I'd really appreciate some help and some input :)

Actually, turns out my fans were not set up that way. The rear fan and the top rear fan wear set to intake air into the case. Once I flipped them everything cooled down and no longer has any issues (for now). So it WAS probably a CPU temp thing but as long as there is good air flow it works fine. I have space for 3 more fans and will probably get more soon.


TLDR; fans weren't set up right, it was temperature related, now fixed.
