Hi Folks, can you help me out

Hi, my laptop is often locking out at 100% CPU usage which is obviously suspicious. Can you take a look at my log? Much appreciated.

Hi heracltus

Which process uses the most of CPU when 100% CPU usage happens?

Hi there, its Firefox and I my machine locks out quite frequently.

keith

Hi

Then I suggest that you uninstall and re-install Firefox first and let me know if it helped.

Ok many thanks, will do so and liaise
