If your computer is running slow it may be for a number of factors such as a virus or your hard disk becoming full or that you do not have sufficient memory for the programs you are running. In this article I'll concentrate on how to speed up your PC with more memory. An important factor that determines how fast a computer runs is the amount of memory called RAM (Random Access Memory) that's in the computer system. When you have a small amount of memory for the application programs you are running the computer is going to have to spending time (processor time) swapping information in and out of the limited amount of memory into the hard drive. If the processor is spending time swapping data in and out of memory it isn't spending time on running your applications. With extra memory added to the computer system (assuming space is available) more applications or data can remain in memory, reducing the amount of time wasted swapping information in and out of memory into the hard disk. If your computer or laptop is several years old and is now running slower than it did when it was brand new, this is probably because new software or software upgrades you have added to the computer are adding increasingly more burden on the existing memory. If you need to find out if memory may be making your computer run slow, ensure the memory usage by running Windows Task Manager. To start Task Manager simply press Ctrl-Alt-Del simultaneously (Vista users should click Start Task Manager) and then click the Performance tab. Make sure the number against 'Available' (or 'Free' in Vista) in the 'Physical Memory' section is getting especially low for instance if it is roughly 10% you probably need extra memory in your computer. Regular Windows XP users will find that 1GB of memory will give them satisfactory system speed. For those people running programmes that do lots of processing on digital video or other large graphics files, or they run lots of demanding programmes at the same time their systems should have 2GB or more of memory. For those aiming to upgrade their computer to run a more moderen Windows operating system then they ought to have a minimum of 1GB of RAM, but for a better Windows experience 2GB or more of RAM will be a pretty good idea. Adding extra memory to your system can only help improve its performance, so if you decided to increase the amount of memory in your computer it's essential to answer the following questions:- 1. Are there empty memory card slots in the computer? 2. Will I you need to remove some or all of the current memory to create space for new memory cards containing more memory? 3. What kind of memory does my computer make use of (yes unluckily there are various kinds of memory)? 4. Is the computer using dual-channel memory, if so then you must install memory cards in pairs? To find the answers to these questions you could study your computer’s manuals, but the easiest thing to try first is to surf to one of the reliable memory card manufacturer’s internet site using the computer you want to upgrade. The leading memory supplier web sites have online tools for identifying the right RAM for the computer you are using to surf to their internet site. These tools can tell you what memory you're currently using, if you have any empty memory slots and what upgrade possibilities are available. With these internet based tools you can clearly see your upgrade choices and they really help to make sure you are buying the right memory for your system. Be sure that when your new memory is delivered you read your computer manual first to know how to open up your computer and properly insert the new memory. You should know that when handling memory any static electricity can damage these delicate memory chips and your computer’s other circuits. That is why you must read the computer manual as it should explain that you have to unplug your computer from the mains electric supply before opening the computer. It should then explain that you will need to earth yourself to the metalwork inside your computer (simply touching part of the metalwork is all you have to do), while removing your new memory from its protective packaging and removing and adding memory to the motherboard in your computer.
