PC Health Check-up – Your Guide to Common Problems!

Ever felt puzzled by your computer’s behaviour? Then read our guide to causes of PC ill-health.

Speed & Stability
If your computer seems to be getting slower and slower, then it might be a sign that it’s due for cleaning, inside and out!

Dust & dirt within computer components are a leading cause of many issues users have with speed and reliability. Over time a build-up of dust can cause serious damage to your PC if left unchecked. Other common signs include:

  • Computer randomly resets itself, stops responding, or crashes for no reason? Try keeping all your software up-to-date by using Windows Update frequently, the hardware may also be overheating. Overheating is a common sign of a build-up of dust.
  • Applications & games are slow to run? You should defragment your computer on a regular basis. Defragmentation is reorganizing the files into an optimized order. Disk defragmenter can be reached from the Start menu, under Accessories.
  • Peculiar behaviour while using your computer? Make sure you have an anti-virus installed, and run regular scans for viruses, check everything is up-to-date.

Computer Failures
Issues that involve recurring symptoms such as not turning on, or crashing frequently can often be attributed to a hardware problem. Signs include:

  • Doesn’t turn on when using the power button? The power supply inside your computer may have failed, or there could be a loose/frayed cable.
  • Computer powers on but there is no output on the Monitor? Monitor cable may be loose, or your Monitor/Graphics card may have failed. In extreme cases the Motherboard may have failed. A Motherboard is the key circuit board inside your PC that regulates all the other components.
  • Windows fails to start? Files on your hard drive may have become lost or damaged, by a virus or computer usage during a power-cut. Other reasons include build-up of dirt, or damaged hard-drive cables and even hard drive failure.

Usage Problems
When operating your computer you may have faced some difficulty with certain aspects of using familiar operations. Common signs are:

  • Unable to read from or write to CD/DVD’s? The laser that is used to read discs in the CD-drive is dirty, and requires specialist cleaning usually, some problems can be resolved by updating the device’s firmware. Firmware is special software to control various hardware, we recommend you do not attempt to update this yourself.
  • Keyboard is unresponsive or keys do not work? The keys may require cleaning; dirt debris from food/drink/smoking can cause significant problems. If this is unsuccessful the keyboard may need replacing.
  • Mouse is unresponsive or jerky? If the device is wireless the batteries may need changing. PC mice operate best on flat non-varnished surfaces, or a good foam-based mouse-mat. You can also adjust the response settings in your computer.

Overall, remember that preventative maintenance now could save your PC later!
