Can't Stand The Slowness? The Top 10 Reasons for Poor PC Performance

Has your computer loaded this webpage yet? If it has, you'll be halfway toward working out just why it seems to be running so slowly. There are many reasons for desktop and laptops to chug along at their own, slow pace, defying the system specs and performing more like a relic from the 1990s.

Where you're browsing the web, word processing or gaming, poor performance will cause problems. The irony is that in most cases, these problems are avoidable, or in the worst case scenario, easily resolved. From relying on old hardware to poor application management, bad airflow and the need to defragment your hard disk drive, the following list will tell you everything you need to know about finding the reason for your computer's poor performance. You'll be able to deal with these problems quickly and in most cases with zero outlay.

1.System Startup

Booting Windows typically takes around the same length of time on any computer - it's when it comes to loading the drivers and startup files that things slow down. As you add software to your PC, any that is required to launch as part of the Windows startup will result in sluggish performance, and perhaps even freeze your computer.

To fix this you will need to reduce the number of applications that are loading at this time. Various utilities can be employed to deal with a slow Windows startup, from MSConfig to the very useful Autoruns.

2.Fragmented Hard Drive

One of the most common causes of a slow computer is a fragmented hard disk drive, although the actual effect of this has been called in to question in these days of faster, larger drives and massive games and media files. Nevertheless, checking the disk for fragmented data won't take too long and can help with dealing with slow performance issues. In Windows, open Start > Computer and right-click the C: drive, selecting Properties > Tools > Defragment Now and following the instructions displayed.

Note that while you can't defrag an SSD, you can optimize it for peak PC performance.

Copy the highlighted text or selected item.
