Alpha R2, possible GPU issue

Hey y'all,

I'm having a fun time getting my Alpha-R2 to play anything more taxing than Crusader Kings 2. Possible GPU issue (fans speed up, screen goes black). After a little while in any game, there while be a click, and the screen will go black while the fans speed up. Scanning for errors and updating my drivers has done nothing; my computer doesn't think anything is wrong. Here are the specs in case anyone needs 'em. Any help is greatly appreciated.

• CPU: Intel Core i5-6400T (2.2GHz, four threads)
• GPU: Nvidia GTX 960 4GB.
• RAM: 8GB DDR4 (SODIMM format)
• Storage: 500GB 7200rpm Hard Drive
