I have a CD macbook, and when I turned on my screensaver, the screen just went black. I restarted, only to find items in my trash. It's a folder called "Recovered Files" and in it are documents called "dftmpAOMMPHBMnkkkkkkk--------" and similar things. Also, there are folders called MSau_489, MSau_602, and plugtmp. Any idea why the screen blacked out and these files are here? Thanks.
