[SOLVED] Computer Freezes for seemingly no reason?

Mar 11, 2018
First my Specs:

Windows 10 (Clean installed)
AMD FX-9590
16GB Ram Dual Channel DDR3
Gigabyte Technology 990FXA-UD3 R5
Nvidia GeForce GTX 1070 (EVGA) (Brand New)
120GB SSD and 2TB Hard Drive
650W Power Supply

I've just started playing on my computer again after about of year of inactivity. My only problem right now is when ever I start playing Rainbow Six Siege about 5 minutes into the game my computer will completely freeze, no sound, no mouse movement, no key stokes will work. I recently bought a brand new super clocked graphics card to try and see if that would fix my problem but it still persists. I have put new thermal paste on my CPU and dusted my computer out. I have tested all sticks of ram, my computer has no problems with overheating, all drivers are up to date and the integrity of the game is fine.
Rainbow Six Siege is the only game I have Downloaded and play.

I'm at a lose, any help will be greatly appreciated.
