Illustrator Freezing

Morning All,

Our Illustrator freezes around 10-20mins into each session.

We can't work out any rationale behind the behavior. Sometimes it freezes whilst another adobe product is in focus, sometimes whilst we're working. Freezes irrespective of the file, new and old. Irrespective of the tool or action being used. There doesn't seem to be a pattern.

We're on Windows 7.

Top spec Dell machine.

No printer directly connected, a large konica is networked.

We're up to date with all software, drivers etc. Running CC 2017.0.2

Illustrator recovers our files every time but it's incredibly frustrating all the same.

Any assistance would be greatly appreciated. Let me know if I've missed any extra info required regarding the context.
