I tried some different ram, got excited cos it let me play for about 20mins but then crashed again. I went into reliability monitor and there was no reason for it, it just said windows wasn't shut down properly etc. This time though I didn't get bsod, the game crashed and seemed to restart my system.
EDIT - I then restarted the sims, with the ram in the same slot played for 5 mins bsod fans going mad and dsm the culprit again.
Swapped the ram into the other slot, loaded up the sims had about 10mins before it crashed with bsod and fans again so I'm not sure what that means.
It did feel warm when I was swapping things around, we purchased a new fan which we put in yesterday to try and help. Could my graphics card be getting too hot?
My partner has bought me a new psu - he think this might have something to do with it - it is due to come either today or tomorrow but I'm not sure if it will do the trick.
