Encountering problems with your computer can be frustrating and can lead to lost data, slow Internet speeds, or loss of your Wi-Fi signal, just to mention a few issues. Here is a look at common computer problems and how you may be able to fix them on your own. 

System is slow

This is often caused by a buildup of temporary files or having numerous unnecessary programs running simultaneously. Simple computer maintenance can help resolve most of these issues and get better speeds from your computer. For starters, keep track of all your programs and shut down any that aren't being used. You should also delete all temporary files and clean up your computer registry using a clean-up application. 

Internet connection issues

If you are having problems accessing the Internet, check the Internet-connection cables at the back of your computer and ensure they aren't lose. You should then ensure the Wi-Fi setting is turned on and reboot the router.

Unstable wireless network issues are also common, and they often result from radio-wave interference or a weak signal from the router. To fix these issues, consider changing your radio Wi-Fi settings so they aren't interrupted by waves from your cordless phone or even the electric garage-door opener.

You may also consider moving the router further away from appliances such as radios or TVs that could be causing interference. A weak Internet signal will often result in a failed connection when you are trying to access the Internet around the house or in your back yard, and this issue can be solved by installing a wireless repeater to extend the signal range. 

Computer shuts off by itself

This can be highly inconveniencing and can often lead to lost data or damage to the hard drive. The problem may be caused by loose power cables or ineffective fans that cause the computer to overheat. Try reconnecting all the power cables, and then run a hair dryer over the CPU to clear the fans of any dust and debris that could be impeding their movement. If you are using a laptop computer, the issue could be a deteriorated battery that needs replacing. 

To prevent the loss of data in case the computer shuts off unexpectedly, make sure to always back up your files to a hard drive or cloud service. Online backup solutions are preferable, as they can allow you to access data remotely and ensure no loss even if your hard drive or server is damaged.
