I've been testing my new PC (not as much as i'd like) over the past week and it hasn't crashed so I think we've identified the issue as a faulty ram chip. A courier is due to pick up the faulty chip tomorrow at whilst i'm at work and replace it with a new one. Let's hope it works when I replace it at the weekend. Otherwise it's a motherboard issue and I think i'll just send the whole thing back.
64gb ram is much better than 48...
I can now play Total War Warhammer 2 without the surface struggling. I've also tried Pillars of Eternity II and Battletech with the new graphics card and they all look wonderful. I re-installed Fallout 3 (New Vegas) and Skyrim last night (April was out) and gave them a whirl but don't think I have the commitment to play through them again.
There are 2 or 3 other games that I own on steam that i'd like to revisit now that I have a computer able to run them but I'm now also looking for a new game to play (before the new FM release next month).
I'm also interested in running a game through the PC as a host and playing it downstairs on my laptop.
The fun i'm going to have whilst unemployed (6 work days left of my contract!!!)
