Problems when exiting the game

[caravel]

I honestly can't remember what the in-game resolution is set at. I think I had it maxed out, but I can't say for certain.

Setting all resolutions to the native resolution might do it - well it'll rule out the resolution being the problem anyway.

I'm in the process of returning it so I can get it exchanged for a new one. Probably going to be at least a couple weeks before I get the replacement, however.

You didn't flick the red voltage switch on the back of the PSU did you?
