Hi, first off I'm on Windows 10.

AMD fury X
AMD fx-8350
8gb RAM (idk much more than that)
GA-990fxa-ud3 am3+
1tb WD black hard drive
850watt gold edition evga psu

Recently I've been having my PC lock up on me while playing The Division, I get anywhere from 60 to 120 fps (144hz monitor, I like my fps > resolution) and it'll freeze. Someone's once after a bit then not again all night. Tonight is been a few times even while playing a less intense game like league of legends. The CPU temp is usually around 72 on division and 50 on league. I just cleaned it (it's at 50 on division now) so I hope it helps. But if it froze at 50 on LoL idk

Any suggestions would be lovely
