Random freeze and crash

Maybe someone can help me out with an error message I'm receiving. I was on the 3rd boss of ST today and the game staggered about 3 times in 15 seconds before completely freezing for a good 10 seconds and crashing.

The following is a paste of the Event Viewer:

Sorry but I'm not very tech savvy, so just let me know if you need any more information than this. I froze up one other time about 15 minutes before the big crash (just 1 stagger). This is a new build but I made sure all the drivers were up-to-date (I think). Thanks in advance!
