Answer 2

This is for XP:
open My Computer
right-click C
select Properties
cl Tools
from here you can run an error check and defrag

***************
If you take the time to run through this checklist, you will find your system's performance much better:

1. Set wallpaper and screensavers to blank or none — they run continuously in the background and use memory.
-----right-click on the desktop, select Properties
-----click the screensaver tab, on the left where it says "screensaver," select none.
-----click the desktop tab, for background, select none
2. Review your start menu – remove anything you don’t need on a daily basis — load games, etc. on an as-needed basis.
-----click Start, Settings, Taskbar and Start Menu
-----click the Start Menu tab
-----select a program you do not want to load at Startup, then click remove.
-----Caution -- do not touch anything you are not sure of or you will mess up your computer royally.
3. From Internet Explorer, click Tools, Internet Options: delete cookies, delete files (offline), and clear history. (You can also set days to store history to 0.)
----- These actions will clear your computer’s cache. (For a description of cache, go to http://help.yahoo.com/l/ph/yahoo/mail/access/access-27210.html )
4. Run Disk Cleanup, Scandisk, Defrag at least every two weeks (the more frequently they are run, the less time they take).
-----These can be found in Start, Programs, Accessories, System Tools.
5. Periodically, click Start, Programs, Run — then type ipconfig renew
(that’s ipconfig space renew).
6. Optional: Speed vs Goodies — in the Control Panel, System, Advanced, Performance, Settings — you can have visual effects or let Windows select the best options. I am using “Best Performance.” Your choice.
These things should increase speed and free up memory as much as possible.
