Top 10 Reasons Why Your Computer Is Slow

We’ve all heard it before. “I need a new computer, this computer is slow and old”. This is actually a myth, and there is no reason that an old computer can’t perform as fast as it was they day you bought it. Buying a new computer is a great experience, but it is also a little challenging since it can take days or even weeks to get the new computer running just like your old computer once you transfer all your data, programs, and settings from the old device to the new one.

Whether you buy a new computer or not, we recommend that it is worth the trouble to get the old one working great.

Here are the top 10 reasons why computers become slow.

1. Free Space. One of the keys to a well performing computer is maximum free space. The more free space Windows has, the quicker it can do its chores. More importantly, without ample free space on the disk, Windows can go into a critical condition called thrashing. Thrashing occurs when both memory and the disk are full. Windows tries to move things from memory to disk to free up memory, but since there is insufficient space, the system begins thrashing.

The secret is to remove large files from your hard drive as soon as possible. Remember that video you watched two years ago? Once you watch it, you should delete it or store it in another place.

2. Windows Revisions. Windows updates itself approximately once a week. You have no idea why, but Windows reboots itself and installs its patches supposedly to add new features and plug security holes. That is all well and good but the problem is that Windows leaves behind a huge mess on your disk each time. The largest culprit are uninstall points. These points allows you to roll back to a prior revision of Windows. The problem is that these uninstall directories are humongous. Gigabytes of useless information. Literally, we have seen systems with over 100GB’s of these directories.

This is a major problem with Windows. Even if you do nothing, these uninstall  directories are so large, it is possible that you will run out of hard drive space and then your system becomes unusable.

3. Windows Restore Points. Almost as bad as Windows Revisions are Windows Restore Points. Don’t get us wrong, Windows System Restore is an invaluable function and has gotten all of us out of a bind or two. The problem is that these restore points are huge, and they are designed to use up 12% of your hard drive. The problem is that on a 1TB hard drive, Windows will then lock up 120 GB for restore points. By our calculations, that is enough to give you close to one year of restore points. Although it is good to have Restore Points, no one can possibly remember the state of their computer one year ago, and hence one should delete these restore points and save the hard drive space.

4. Fragmentation. Perhaps one of the largest contributors to slow performance is disk fragmentation. Once a disk becomes sufficiently fragmented, it literally takes 10 times as long to read and write basic information from the disk. Simple tasks such as loading an application, or viewing a web page can take 10-15 minutes on a fragmented system. Microsoft reocognized this problem and includes automatic defragmentation as standard on all Vista and Windows 7 systems. XP systems have only a manual defragmentation, requiring the user to remember to defrag. On approximately 15% of Windows 7 systems, there is a bug where about 15% of hard drives will not defrag automatically.

5. Internet Cache. Did you know that Windows stores every image you view on the Internet on your hard drive? This is really a remnant of when we accessed the Internet through poky dial up modems. Back then, since the images were on your hard drive, the dial up modem and your phone line had less work to do.
