Hi Eddy/TwinHeadedEagle
It was the CPU (a dual core processor) running at 60c. I’m a bit braver when it comes to hardware and so I’d already removed the PSU and cleaned inside, though it was pretty spotless anyway and nothing obvious blocking airflow. Fan bearing was also nice and smooth so no obvious hardware problem.
Thing is, after TwinHeadedEagle’s interventions - well, in fact after removing the Malwarebytes - it has been running much quicker and the temperature of the CPU is half what it was. No error messages, Avast beeps/alerts or anything. Fingers crossed! Thanks everyone for helping
Great forum BTW.
