Why does your computer crash in caves only while playing skyrim?

Answer 1

If you find you are crashing often indoors anywhere in Skyrim, try purging the cell buffer. You can simply do this by opening the console and typing PCB then enter. Don't try to do this outdoors as it may take a long time and result in a crash. It clears the read-ahead of elements in an area and will not contain any previously buffered environmental data.

An alternate solution may be mod related. Try to have mods loaded in a specific order where elements don't conflict or have to read several times filing the buffer with useless data. Some mods fail to explain what changes are made if another mod is doing the same thing often leading to a crash.

A final solution is installation related and may have corrupted room data. Try reinstalling the game. You shouldn't lose any saved data as the uninstall will ask you if you want it removed or kept.
