The first thing I did was strip out Norton. That thing is a HUGE resource hog (I had to strip it off my home system and laptop, too). I installed Avast instead — much nicer program.
Aero Glass is turned off, too.
The thing still runs slow. I guess I need to snurch it from her and see what other nonsense needs to be removed.
What does she use it for? A celeron-m I just googled doesnt downthrottle but instead is just a lower powered, half cached version of the pentium-m. One thing to try is a cheap ready-boost capable thumb drive(about $20 online for 2gigs), that should speed things up as it caches programs for faster access and helps aleviate stress on a hard drive.
