Audio stutter that leads to graphics slideshow

rophez_ESO

Since about May I've been having this problem intermittently. I'll be playing my character and everything seems to be going smoothly when an ability sound effect or combat sound effect will have a stutter sound. No big deal, except after that initial stutter, I start to get more stutters, and I begin to lose FPS gradually until I have to actually reboot my computer. I can't tie down what causes it or find a pattern. Sometimes after a reboot, I'm good for many hours. Sometimes, after a fresh boot, the problem starts almost immediately.

Edit to add: I've played other games during this time frame, and not experienced any problems (SLI and non-SLI.) I never run into this sort of trouble, even after days of uptime, unless I'm specifically playing ESO.

Any advice would be appreciated.

My system:

• 2x Geforce gtx 670 in SLI (running most current drivers)
• Intel i7 3770k
• 16 GB Ram
• Sound Blaster ZX SBX PCIE (I actually installed this after the problem started, because I thought maybe my MB's onboard sound chip was cheap/failing.)
• Game is on an SSD (forget the brand)
• Running Windows 7 on a separate SSD(all updates)
