Thanks Again Jack!

Thats good advice. i think it will be better, to look at getting a more modern system to save pain down the line. Im quite keen on the mac mini - i can get a really good deal on it and its a little beast. especially if i can get 64GB ram i it.

I have dropped the slave completely and turned off the internet
Did a Pro Tools session for about 4-5 hours yesterday - running prerty high on RAM at like 80%

Was working great - then computer just randomly shut down.
Im gonna pull up a session now, deactivate all background apps and processes and the internet and see if it still chokes out.
