Random missing files

[saykoshey]

Before you start on about it, no it's not my memmory my harddrive isn;t corrupted and yes I'm sure anybody who dares recommend any test will get flamed.

Since yesterday my console is randomly showing that it's missing files while the files are there. It's most apparent with sounds but from time to time I get missing textures in maps too.

Did you verify game cache?

Just because the file is there doesn't mean they're not corrupted.
