10. Display Driver Has Been Restarted
Windows Vista+ has a feature called Timeout Detection and Recovery, which detects if the GPU becomes unresponsive and restarts the driver. The GPU running at 100% load can inadvertantly trip this reset the driver, causing applications to crash. This can saftely be increased from the default 2 seconds to a larger value with the only negative impact being that an actual crashing driver will take that much longer to be reset. A bump to 8 to 10 seconds is generally ok; it is not recommended to disable TDR entirely.
