How do i speed up my computers performance? Im running windows vista home premium with 854 mb RAM and i wanna run battlefield 2142 faster without buying and shoving more RAM into my computer

The laptop has 3 GB of RAM and a 32-bit operating system. The computer has already been defraged(no speed difference after defrag), scaned for viruses(none found), the temporary files and browsing history has been deleted and the computer is still running slow. What else could be done to make it a bit faster? It takes like 10-15 min to fully load the computer when it has been turned on and 5 min. for a internet page to load

Before I downloaded imvu, and my brother downloaded a game.Now my computer is slower than a turtle. I tried uninstalling imvu and it stop about 75%. I tried closing it but it wont and it froze or something.

How do i fix all of thiss? x.X

I'm playing Rome Total War and it get's very slow when I recruit a lot of units and espacially if I zoom into them to see how they are fighting. It's fine if theres only fewer units so I don't think it's the video card but I think its the ghz because mine is only 1.1. How can I speed up my computer to play the game faster? Are there any programs that speed up computers? Any software I can download or purchase? Anything I can do to my computer?
