Do what Dude1234 said. Also try getting these programs to help speed things up a little bit.
FreeRAM Xp Pro
- This program cleans the clutter out of the memory and can help you get the most of your RAM.
CCleaner (crap cleaner)
- this program is great for cleaning out unused and old registry files as well as other stuff. I use it and it helps to get the crap out of there just as it says
Startup Control Panel
- Works basically like MSCONFIG but it can be run from the control panel. This program is great and it helps you remove startup entries from your system. It's only a few KB (yes KB
) and it's very simple to use.
Also go to control panel and then go to system and go to "advanced" and then under performance go to "settings" and then click "adjust for best performance." It will use the classic theme but also adjust some stuff to make it work quicker.
Hope that helps,
EDIT: I forgot to add that you can get all those programs from download.com and they're all free!
