A Computer benefits from servicing.

Just as a motor car needs to be regularly serviced so likewise does a computer.

The pictures below are of two towers which I serviced a few weeks ago (October 2011). Note the dust in them and also how wires are nearly touching the processor cooling fan in one of them.

Dust is a regular problem but varies depending on where the computer is located. It blocks the vanes of the processor's heat sink and eventually causes the processor to overheat. I always inspect the interior of a desktop or tower computer for this reason.

In this tower the dust had stopped the cooling fan on the processor from working and it burnt out. I had to remove almost every component inside the tower to clean all the dust out. It worked perfectly afterwards. It was clear when I inspected the interior that this would be a big and therefore expensive job so I contacted the customer to confirm he would authorize repairs.

Here the dust is not the only problem. This tower had been supplied by a local company who hadn't adequately checked or secured the internal wiring.  After cleaning the cables were professionally secured away from the fan.

How much does servicing cost?

My charges are amongst the lowest in the area. However you get what you pay for in terms of the attention given to a computer but in general to just check the computer and tune it I would charge around £25 - £35 if it is brought to me and the work is straightforward.

In both cases above the work was not straightforward but A was more labour intensive than B. I had to strip the tower down to the bare shell and remove the heatsink from the processor in order to clean out all visible dust. B was adequately cleaned using a brush and vacuum cleaner. In both cases all software was reinstalled. B was set up to dual boot with Microsoft Windows XP and Mint Linux.

What is done in a service?

The following:-

  • Inspect for internal dust.
  • Remove redundant files from Microsoft Windows installations.
  • Remove temporary files from Microsoft Windows installations.
  • Remove accumulated restore files from Microsoft Windows installations.
  • Check for viruses and malware on Microsoft Windows installations.
  • Defragment Microsoft Windows installations.
  • Optimize programs on Microsoft Windows installations.

Sometimes:-

  • Reinstall all programs on a hard drive.

On Linux installations much of the above is unnecessary. Linux uses a different installation strategy to Microsoft which eliminates the need of defragmentation.
