Put the computer on roller skates and attach jet engines?
If you are wanting to increase the speed of an existing computer, here are the standard things to try:
1) Check for spyware. Run both Ad-aware Personal http://lavasoft.com and Skybot (http://www.safer-networking.org/en/download/index.html) to remove any spyware. Run both as one may caught something the other missing. Then go to microsoft.com and download Defender to protect against future infections. All three programs are free.
2) Check that you have a least 10% of your hard drive free. Go to My Computer and right click on the Local Drive (C:). Look at the properties. If it has less that 10% free space, you will need to delete some files, or move them off the hard drive and on to a CD or DVD. Start by running the disk cleanup, which will remove temporary and other unneeded files. Go to Start, then All Programs, then System Tools and click the Disk Cleanup icon.
3) Run the msconfig utility. Go to Start, then Run and type in: msconfig
Go to the startup tab
You will see a list of all the programs that are loaded when your computer starts up. Uncheck any that you do not have to have. (Usually you can uncheck them all). If you decide you to need one, you can go back and recheck it.
4) Defrag the hard drive. Go into My Computer and right click on the Local Drive (C:). Select Properties and go into the Tools tab. Click the Defragment Now button to start the defrag program. If you have not defrag recently (or never) it may take several hours for the program to complete.
5) If you have extra money, invest in additional RAM memory for your computer. Usually the number one thing that slows a computer is running out of memory. This forces the computer to move some of its running programs or data to a swap files on the hard drive, which is much slower than RAM memory. Every time it has to move something in or outof the swap file, it cause the computer to drag.
