Tip & How-To about Computers & Internet
The most common reason for a computer running slow is insufficient RAM memory.
Check specifications on manufacturer website to find out the kind of memory supported and the maximum RAM allowed.
A computer running Windows Vista should have at least 2 GB to run smoothly.
Increase the RAM, if RAM available is no more than 512MB, then it must be surely and immediately upgraded.
Check also your hard drive free space. If you have less than 1GB free space on hard disk, Windows will have to write continuously virtual memory pages to hard disk, and that will slow down the processing speed. Also check fragmentation. Files pieces may be distributed in different areas of the hard disk, resulting in slower reading speed.
Start>>Programs>Accessories>System Tools>Disk Defregmenter and do a Defrag of the hard disk if needed.
If you have at least 1 GB RAM on XP or Linux, and 2 GB on Vista, and you took care of your hard drive, then you can check the processes that are starting up automatically and remove the useless one, or spot malaware that can affect speed. You can use a software like Hijack This, and search on google te function of each process started on the list reported by the software.
You can download Hijack this here MajorGeeks | If download does not start, then click at the top of the page, where it says Click Here If It Does Not.
Be careful if you delete the wrong files using this software you can harm the system, and Windows may not work properly.
If you think you have malaware you can also install Spy Bot, and do a system scan. Download Spybot from The home of Spybot.
If all the above does not work, and there is no malaware, then you usually reinstall the system.
Check also the bios settings, BIOS can downgrade the CPU speed on default , even if this is uncommon on recent BIOS.
If a computer is still slow with a fresh system and enough resources then it is one of those rare occasions when you have an hardware fault.
Hardware that can cause slow down is: RAM CPU Motherboard HD Video card.
Some tips on procedure can damage your windows installation. Do not download Hijackthis software and do not change BIOS settings and do not touch hardware unless you are sure of what you are doing.
