Thanks for all your responses. The thread went off onto fonts, but that's OK

The reason I asked about system tools is that I am not a computer geek, by any stretch of the imagination. I'm a user, doing the best I can with tools that, hopefully, will bail me out when I screw something up.
Having said that, I try not to screw things up, so I need tools that don't require me to be computer professional to keep me going. I do have two hard drives. I also have my main 60gig hard drive partitioned so that my programs run on virtual "C" and my data is stored on virtual "D". I use my older 13gig drive to store really critical data, like Quicken backups, resumes, and the like; things that would otherwise be unrecoverable, but not yet burned to CD's.
As for system tools, nobody mentioned TuneUp Utilities, http://www.tune-up.com/order/. I read a good review of it in one of the computer magazines, so I downloaded and used it through the 30 day trial period. it seemed to work well, but I'm not really sure *what* it did, though it really seems to be quite similar to Norton Utilities. Also, some of the tools seem so unnecessary and redundant. Now, I need to decide if I want to purchase it for $34.95, or if another one would be better.
Decisions, decisions.........
