While using my desktop it occasionaly restarts unexpectedly, the screen goes a dark colour but my voice chat and sound continues,no error codes or anythign upon computer restarting . I have checked my computer temperatures and nothing abnormal as it usually runs at 40 degrees c. New build running windows 10 with an ssd.

Any help would be greatly appreciated
