Hard Freezes On GTX 960 Suddenly

[FrozenZephyr]

So i just started getting these really random freezes on a few of my games like GTA V and Tomb Raider i assumed that it was the new Nvdia drivers because i haven't noticed these freezes before so i rollback the driver restart my computer load up the games again and its still happening even on the old driver was wondering if there is a program i could run in the background to see a diagnostic of whats causing the freeze because games just lock up for like 2-3 seconds sound still plays but the game is frozen for that amount of time.

I have an i5-4690k
MSI 960 4GB
8GB Ram

i dont have any anti virus programs or anything this problem just started happening a couple days ago
