Claymore Crashing (WatchDog hang error)

Hello, recently I've been having some issues with Claymore Crashing. Here's what the problem is
"WATCHDOG: GPU 0 hangs in OpenCL call, exit
08:32:42:037 1adc watchdog - thread 1, hb time 76254
08:32:42:037 1adc WATCHDOG: GPU 0 hangs in OpenCL call, exit
08:32:42:037 1adc watchdog - thread 2, hb time 125
08:32:42:038 1adc watchdog - thread 3, hb time 328
08:32:42:038 1adc watchdog - thread 4, hb time 16
08:32:42:038 1adc watchdog - thread 5, hb time 219
08:32:42:038 1adc watchdog - thread 6, hb time 76222
08:32:42:039 1adc WATCHDOG: GPU 3 hangs in OpenCL call, exit
08:32:42:039 1adc watchdog - thread 7, hb time 76020
08:32:42:039 1adc WATCHDOG: GPU 3 hangs in OpenCL call, exit
08:32:42:039 1adc watchdog - thread 8, hb time 156
08:32:42:040 1adc watchdog - thread 9, hb time 63
08:32:43:100 1adc Restarting OK, exit..."

Whenever this happens, the whole computer freezes (Not using the computer for anything else) It is interesting to note, though, how GPU 4 doesn't hang like the others.

What might be causing this, it wasn't running for very long when it did this. Yesterday it ran for 24 hours and 2 minutes, then did the same thing.
