Five Solutions for a Slow Computer

By Gerrard E Felman


Sometimes a computer can get a little sluggish, especially if it's an old model. Malware and hardware failures will certainly slow things down, but for most problems you can fix things by having a bit of a spring clean. A useful tool for this is the ChkDsk utility. This is an inbuilt program for windows XP onwards which will look for bad sectors which have developed in your file system, and recover them to help things run faster. To open this program, click 'run' then type chkdsk c:/r is you'd like to repair the C drive. For other drives, replace the 'c' in the typed command.

When you install new applications or accept updates, they can often insist on being part of your system startup list. Much of this doesn't need to be activated as soon as your computer starts, so by deselecting them you can really speed up the process of getting your computer working. To do this, click 'run' then type 'msconfig' and hit enter. Go to the startup tab, and unclick any box that's not essential. It doesn't mean the program won't work anymore, it just means it won't start unless to click on it to start once your computer is up and running.

Updates can slow down your computer in a number for ways. Having updates set as automatic may account for sudden periods of CPU being eaten up or internet spikes, but also if you don't check updates regularly you might find that internet applications require updates to run. Check for updates on internet, and make sure they're all working correctly.

The drivers for your system may be out of date. Run 'devmgmt.msc' and check your current driver update info. You'll be able to see a date of the last update, as well as the details of the driver's ID. There's an automatic update system from windows which doesn't actually work for most device drivers, so check manually for newer updates by going to the manufacturer's website, and then just download and install.

Finally you can use the defragmentation option in your tools menu to help fix connection problems across your hard drive. This won't fix serious problems, but it's a good idea to do regularly to keep things clean.
