What are the components of the computer? make, model, processor, ram etc will help.
Did you reinstall the motherboard drivers when you reinstalled windows? When you reinstalled windows, did you use an OEM restore CD, or just a plain ole copy of windows?
A little thing you can do to speed things up - Open my computer. Right click on a partition, and choose "properties". At the bottom, there should be a little box that says "allow windows to index this drive..." Un-check that, apply to all subfolders, ignore all. Go get yourself a sandwich. After you've enjoyed your tasty treat, repeat for all partitions, or, if you just have one, you're done. What windows does is index the partition for faster file searching. This takes a performance hit on your computer, and doesn't really do anything anyway, so might as well get a performance increase.
Also, do you see a performance difference between when the laptop is plugged into a/c power versus operating on battery alone? Some lappys like to cut power when they're on battery, sacrificing performance for run time.
If you've had it for a while, it might prove fruitful to (if you're up for it) take the case off and blow any dust/dirt/dead bugs that might have gotten into the chassis, especially around heatsinks, fans and vents.
