For a good gaming
 

This is what I learned and will help.

After playing for 4 to 5 hours, delete your temp files, and flush out your ram/memory. Then every 2 to 3 days, Defrag your computer and also flush your memory and then defrag again.

If you have windows 7 or vista, enable auto defrag. It will defrag your computer without hurting your game play.

Also one more thing. Update your video drivers.:degen:
