When animation rendering is ongoing, my desktop suddenley stoped quite often, and I needed to reboot it. The GPU driver's already set up properly. I'll appreciate the cause of this problem and the solution. Thank you.

Are you sure you are asking for FurryBall 4,8 and not RT??

Try to check TDR level (see https://msdn.microsoft.com/en-us/library/windows/hardware/ff569918(v=vs.85).aspx).
For FurryBall 4.8 and older: Set TdrLevel to 0 (disabled) or to 3 (3 is default, so if no TdrLevel key exists, this value is used) and set TdrDelay to for example 1000 (it means, 1000 seconds ~ 15 minutes).
For FurryBall RT: Set TdrLevel 3 (3 is default, so if no TdrLevel key exists, this value is used) and set TdrLevel to 15 for example (it means 15 seconds - in most cases it is sufficient).
Note: TdrLevel = 0: graphics card will be never stopped by Windows, so it can cause your problems.
TdrLevel = 3 and TdrDelay = graphics card may not respond during this delay, after that, Windows should stop it.
