Sorry no idea, never experienced that ever in my 160+ hours of play. Had some crash to desktop stuff, but nothing major.
Have you tried setting your sound to, I think 44Khz & 16-bit, in your Control Panel, I think I remember something like a sound setting causing crashes.
Some crashes also stop if you disable AA, V-sync, etc. Hope that helps or do what I did, put the game down and play it again, once they fix their borked game...
I've been trying to get a hold of Skyrim on the xbox for weeks, seems suppliers are sold out and don't know when the next shipment is coming is :/
Ive checked Zaps, AWX and called Btgames, none of them seem to have stock in JHB. Im gonna go check CNA tomorrow. But they those type of stores all sell at R600 for newish games... Oh well :/
