My operating system, Window XP Pro seems to be sticking. No matter what program I'm in it seems

I've maxed out my memory with 3GB and it's really slow. Does anyone have any ideas what could be causing this? I've had antivirus software on there from day one, so that shouldn't be the cause.

As you will appreciate there are many reasons why your computer is running slow:

First of all make sure you do not have any malware in the form of viruses or spyware. Run your anti virus and anti spyware programs in order to clear out any beasts.

If you do not have any protection these are available for free:

Your hard disk may be getting full. You need at least 15% of free space for it to operate efficiently. Go to Control Panel %26gt; Add/Remove Programs %26 remove any applications you no longer use. How about removing all those pictures %26 music that is filling up your hard drive?

Finally, after you have done all the above may need to upgrade your RAM. So that you get the right type of RAM for your system do a free scan at Crucial to determine your RAM.
