Thanks for that, but I ended up going into Boot Memory, and then something along the lines of starting in a separate partition (can't remember the exact wording) and now I'm running a fast check of the hardware.
I only have one hard drive, and it's all word/excell documents so it won't have chewed up too much memory. Of course, I'd really like to get all those documents back.
I'll let you know what it says when the quick test finishes in about 15 min. Thanks.
