Very Long Loading Times, Fairly Often Crashes

[Outlaw_Spike]

So this is a new problem I'm having since one of the more recent updates. It goes something like this:

Game loads in fine
Can go through menus
Can select a team
When it tries to load into the actual game, one of five things happen:

1. It loads normally, no problem
2. It sits on the loading screen for an extended period of time, eventually loading in (if it was an online match, it times out and starts the round with a disconnect)
3. It sits on the loading screen for an extended period of time, eventually loading in after appearing to almost crash (loading screen stops moving, windows treats it like a dead program briefly)
4. Game freezes and I have to shut it down through task manager
5. Freezes up my entire computer and requires a full restart of my system​

Have this problem in both beta and retail. Already verified the cache on both version and tried with 2D backgrounds.

Any advice on what to do? Any extra information I can provide?

Thanks!

Edit: Turns out it was a HDD issue. Issue resolved.
