    Hi All,

    I was running an online training yesterday and realised my mouse and keyboard were no longer working. This has happened before and I've had to force shut down in order to get everything back. Yesterday, of course, I couldn't. After a while, the screen went black, though the webcam was still working and a text message to my phone said the class could still see and hear me.

    After a few minutes (fortunately, just as the session was ending) there was a series of loud chimes before everything stopped.

    Rebooted, and all seems fine... but now I'm having the heebies because I've got more classes to do next week! No idea where to look to find out what the problem is, so I hope somebody here can help.

    Terence

    Applications > Utilities > Console. Have a look in there for details about what happened at the time of the issues. The problem may have been caused by an Application (what were you using at the time?) or a general system issue.

    If so, Google search for Rember, a memory tester utility and run a test. Are you using third party RAM? This can be the cause for random crashes sometimes...

    Thank you - It's just happened again and after rebooting I had a look at the console. Thank you for that advice. I'm afraid the only bit I can understand though is: 'Stopping'! If you know about these things and if you have a couple minutes, this was what showed up:

    I totally understand if you don't have time for this, but I'm a total dunce at this sort of stuff!

    Nothing immediately obvious, but I am walking the dog. Run Rember and see what the results are.

    Yes, I did that - no faults reported. I have had Crucial memory in there for about 18 months...

    Thank you for helping!
