There are also apiaries scattered around. Honeyfill meadworks east of Novigrad for instance has several beehives, they look like mini towers, you can loot them for honey comb.
I looted several last night.
This sounds like a hardware or PEBKAC issue.

What motherboard?
How much RAM?
What OS?
What power supply?
Could it be a overheating issue, does everything have good airflow?
If running through Steam have you verified the file...
