    Hi, diagnosing System and Compressed Memory problems can be tricky. Please feel free to search the forum for threads on this: just type System and Compressed Memory in the search box above and you'll get quite a few results.

    Here are some I've collated. Please look through these carefully, then post back. Good luck.

    Removing HDD caddy and switching jumper in it resolved this issue.
