Dorsetdog - Tips for your computer

Does your PC run slower than it used to?
 
Here are some tips to help your computer run more smoothly




I am slowly creating handouts in PDF format for the various PC maintenance processes show below, which viewers will be able to print off and work from. I am aware that some users get confused between the guide on the screen and the actual task at hand - so I hope that these "How to" guides will help people.

Mean whilst - In order to carry out maintenance work on your computer, and read the "On screen" instructions at the same time - it is advisable to reduce the size of the web browser window so that one can view the instructions by the side of the work that one is doing

De-frag

Speed up Windows by Defragging the Hard Drive

Every time that we start a computer, it needs to open files in order to run. When some of those files close, they can be larger than when they were opened. If we create documents or edit existing documents, then they also have to be saved onto the hard drive. The problem is that the files are now larger than when they were first opened, so the whole file is unable to fit back into the same space. The result is that the files are split, with part of the file going into the original space, and the rest of the file is stored further along the hard drive. As the computer is restarted over time the files get bigger and bigger, and become scattered in numerous segements along the hard drive - or Fragmented. So the computer takes longer to find them, longer to work with them, and longer to save them.

The cure is to defrag your hard drive, so that the files are stored in individual places on the hard drive.

Defragmented hard drive

The ideal is to have the hard drive at 0% fragmented, so even 10% is high and will cause the computer to run slowly. If it get seriously fragmented then one might consider formatting and reinstalling Windows.
This hard drive is so full that it does not have enough room to gather the files and relocate them as whole files.

Click on Defragment disk – and leave it running

You may have to run Defrag a few times until the list of unfragmented files is reduced to no files.
Sometimes with Windows, it is necessary to start the defrag process twice. This is because on the first Analysis Scan – Windows does not think that the drive is defragmented enough to need defraging, so you can force it to defrag by clicking on Defragment Now a second time.

Ideally, you would run this once every 6 months or so. Newer versions of Windows do it automatically, but I still like to do a full defrag, even on windows 7.

Unwanted programs

Unwanted programs take up hard drive space. That is storage space where you could store more pictures or files. Drives that are too full will work more slowly, and will not Defrag properly.


Never delete a program – always Uninstall from Control Panel

If you previously tried to delete a program that you no longer use, but it is still displayed in the Programs list, or keeps appearing – then you need to re-Install it, restart the computer, and then Uninstall it properly.

Click on - Start – All programs. Write a list of all programs that you have never used, or have stopped using, and wish to uninstall.
Note - Programs like Adobe Acrobat, and Quicktime, are needed to view specific files. If you find after uninstalling programs that something will not open, then go on line to reinstall the appropriate program.
Then
Click on Start
Click on Control Panel
Then – *
*) On older versions of Windows, chose Add or remove programs 
*) On newer versions of Windows, chose Programs - Uninstall a Program. 

Click/highlight on programs from your written list and Uninstall.


Do not uninstall any programs that are not in the Start - All Programs list.

Uninstall unwanted programs from Windows, do not just delete them

After all unwanted programs have been Uninstalled, restart computer – then run Defragmentation, and restart again.

RAM Memory

Checking RAM amount. 
Auto scan your PC "on line" for advice on upgrading PC memory - Please see the NOTE at bottom of thread

If your PC is generally slow, or slowly displays your own pictures – then it might need more RAM memory. RAM is just as important as processor speed and hard drive size. 3 Gigabytes or above is better for a smooth working computer.

Remember – 
Hard drive is the permanent storage memory, where programs and files are stored until you delete them. RAM memory is where files and pictures are placed whilst you work on them, and are lost if you forget to save them before switching the PC off.

RAM is a module or strip that plugs in to a specific slot inside the computer. See thumbnails below. 
On Laptops, and desktops with “Onboard video chips" rather than separate dedicated video cards – a proportion of RAM is also used as display memory, as they do not have dedicated video memory (VRAM). So if you have say 128 Mb of memory, a large portion of that (maybe 32 or 64 Mb) will be unavailable to windows.

To see how much installed RAM you have, go to
  1. Start
  2. Control Panel
  3. System, where it will give you details of your machine. 
Please see below, for different versions of Window.

Operating System properties of Windows XP, and all before XPOperating System properties of Windows Vista, Windows 7 - with Dorsetdog.com



















The length of RAM, and number of memory slots in a computer, has changed over the years – so it is important that if you do buy more RAM, that you buy the correct size and correct speed for your PC.


Increasing the RAM memory amount significantly increases computer speeds

Crucial are a recognised memory manufacturer. They can scan your PC’s configuration, and advise if you can install more memory. Simply click here and click on Scan my System.

Increasing RAM memory will greatly increase the speed of a computer


Note – a standard version of Windows runs at 32-bits, and can only see, and use, so much memory.
Please note. The older the PC, the smaller the maximum amount of RAM that can be installed in it.
If you wish Windows Vista, Windows 7, etc, to recognise and use more than 3.5 Gb of RAM, then you need to install a 64-bit version of Windows.

1024 Megabytes (or Mb) = 1 Gigabyte (or Gb)

If you are apprehensive about opening your PC, then places like PC world charge to install memory for you.

Opening the case

If you do open your computer’s case - Ideally, you would not wear any jumper or other clothing that creates static. One would do the operation sat at a table, rather than stood with your feet moving around on a nylon carpet – as that builds up static.

It is imperative that you discharge any static electricity from yourself before opening a computer – this is usually done by touching the earth wire connected to the water pipes below the kitchen sink. 

You must not use an electric screwdriver, or magnetic screwdriver tips – as you will cause magnetic damage to the PC and render it useless. If a screw sticks to a screwdriver – then the screwdriver is magnetic.

On a desktop - The mains lead must remain plugged in, but switched off at the wall socket. You should touch the metal screws near to where the power lead goes in, before opening the case. This ensures that you are static free, and, by the case being earthed through the mains lead, usually prevents any build-up of static.
