    Using a registry cleaner can clean up your computer and then make your computer faster,Why?the reason is that there may be some regsitry errors and remnant,corrupt files and temp files in your computer to cause "computer slow".

    Everytime you install and uninstall software on your computer and surfing online you create junk in the computer registry.over time, the registry can grow to enormous proportions, especially if the various programs you've installed do not do a good job of deleting and/or updating it's Registry entries.You need to scan and clean your computer with registry cleaner to make it fast.Good Regisry Cleaner will improve your computer and Internet performance dramatically!It even can speed up your computer by 300% or more!

    There are some comparison and review of TOP 5 registry cleaners.

    You can download and scan your computer for free.

    If your virus/spyware free, there are a couple things you can do get your computer working faster. If you using your computer for normal stuff and not gaming. You don't always need more RAM you just need to perform a few maintenance task.

    First, if you haven't cleaned your registry in a while. This is necessary. Your registry holds all the information regarding updates, installs, un-installs etc. Each one of those events produces a key. That key needs your PC's resources and free space. So, if you clean your registry, you make more resources available for speed. Do a registry scan if you got more than 20 errors you should clean it.

    2. Clear your Windows cache files, this is your temporary file. It can grow up to a large volume and stop your computer from using RAM properly. In a sense slow it down by preventing it from using free space.Here is how:

    1. Quit Internet Explorer, Firefox, or any other web browser

    2. Click Start, click "Control Panel", and then double-click "Internet Options".

    3. On the General tab, click "Delete Files" under Temporary Internet Files.

    4. In the Delete Files dialog box, click to select the "Delete all offline content" check box , and then click OK.

    5. Click OK.

    3. Manage your startups. Your excess CPU usage is due to too many programs running in the background. You can cut these to barebones by alter your msconfig. Here is how:

    1. Open your Start menu.

    2. Click Run

    3. In the command screen type "msconfig.exe"

    4. In the "system configuration utility",click either "service" or "startup" tab

    5. Uncheck all programs that your are no longer using.

    6. Click "OK"

    Other great tip is increasing your virtual memory to simulate more RAM. This will give you a bit more resources for multiple program use or CPU heavy programs.

    Hope this link helps. Shows you how to do everything step by step. You should get a least 60-120% more resources and speed

    if you follow the tips.

    Have you scanned for Spyware? If not download, update and scan with Spybot and Adaware. How long since you ran a diskcleanup? Is your drive free from fragmentation? This disease can slow things down. Keep a check on frag levels and also on the free space.

    You do not have enough information in your question to get a really good reply.

    Is it a PC ? y/n.

    Is it running Windows XP Home, XP Pro, XP media center??

    Is it reading in video from antenna or cable???

    Now I assume you are running XP.....

    Go to the device manager.....

    Start >> Control Panel >> System (in classic view)

    First tab shows CPU type and speed.

    Intel has a CPU ID utility program on its website, and a

    CPU frequency (speed ) utility too.

    Intel CPU'd LAPTOPS have speed step that slows down to

    save battery when idle.... THEY don't slow down when on

    line power.

    Symantec / Norton NIS or Anti-Virus can bring a Pentium 3

    1.0 GHZ to a stand still if it's on cable TV based broadband due to Anti-virus updates. Same goes for Windows updates, and Google Updater.

    >>>Google Updater will restart itself in the background even if you kill it manually in the task manager !!! Surprise!!!

    VISTA Aero is still having major problems and can get "Lost"

    in the video driver.......

    LAST go to the last tab in System and increase the virtual

    memory // page swap file size.....

    if you have too many virus programs on your computer one or more of them may be incompatible with another one. also, spyware and viruses are not the only problems that can go wrong. a lot of problems can arise in your registry, memory, and hard drive. try defragmenting your hard drive and try sacnning your registry memory, all your files, etc...that should help a lot

    If you are running windows go to start-accessories-sytem tools- disk clean up and run that. And start-accessories-sytem tools-disk defragment and run that. To find out what is making your computer slow press control-alt-del and then go to process and sort the mem usage so it shows you the process that is using the most memory and if it is unimportant click it and click end process.

    You should check your cookies. You can do this by searching cookies, then you need to delete the ones that are from websites that you don't have your password saved on. You can delete all of them but then you will need to save your password again. If this doesn't work try adding more ram.

    Source(s): I recycle computer and some times rebuild them.
