Computer Hardware – Info for Beginners

There is more to your  computer than the monitor, the keyboard and the mouse, though most of the other components are hidden away.

In that big box that you often complain about being too bulky, lies the heart of the computer.

It houses all the vital parts that make your computer fully functioning.

Get to know some of these parts.

  1. The processor or CPU (Central Processing Unit) determines how fast your PC will be & is perhaps one of the vital parts of a computer, if not the most vital. Having a fast processor will allow your computer to convert data faster

Software Crashes – Prevention & Recovery

These days, most of us have a lot of software on our PCs and we need to know how to take care of our system to minimize the possibility of a crash.

(For beginners, the following words  have a computer specific meaning)

1. Crash – When a program or your entire computer stops working and you cannot move the mouse or use the keyboard, and the screen is frozen.

2. Reboot – When you restart your computer after a crash.

3. Control Panel – A feature of Windows that will give you access to system utilities and settings.

4. PC – just another term for your computer (short for Personal Computer – from early computing days)

What should you do first if your PC crashes? Try to stop work, go away & leave it for a few minutes. Often, the computer is trying to process a whole string of commands and might just need to take a little more time. Pressing more keys will just add to the computer’s processing queue, maybe even forcing a crash.

Most of the time the hardware is OK, but the software has caused a problem. A good way to try to recover from a problem is to press the Ctrl + Alt + Delete keys. In XP this will open the Task Manager and show you all the programs running. Note that at least one will probably have a non-responsive indication. Try clicking one at a time on the programs listed that are “Not Responding” and click “End Task”. After that, close the dialog box and see if your computer is working again.

This should solve about 98% of your crashes. If your computer is not responding after all this, you can try restarting. Switching off the entire power is the last resort and should not be done unless everything else has not worked.

To prevent computer crashes, it’s worthwhile to carry out ongoing file maintenance. Check that you have room on your hard drives. To do this, open My Computer and right click on the drive you want to check (e.g. C:) and then click “Properties”. You will get a pie chart showing how much used & free space is on the drive. Windows needs plenty of working space & the suggestion is not to go over 70% usage of your total hard drive space.

You may need to delete or move  any large audio or video files that are occupying too much space to another hard drive or a CD.  When you are short of space,  it is also advisable to remove software programs that you don’t use by going to “Start”, “Control Panel”,  “Add or Remove Programs”.

Make sure you have enough Memory or RAM (Random Access Memory).  If your RAM is low,  help out your computer by not opening too many programs at once.  To find out how much RAM your computer has, select Control Panel from the Start Menu, Double Click System Tools, and then open the System Information tab. The total and available memory is listed towards the bottom of the right panel when you click on System Summary.

Software programs that use the most RAM are those that include a lot of graphics, video or sound capabilities. If your system runs slowly and you use this type of program a lot, it might be worthwhile to upgrade your RAM

Back up your hard drive regularly. There are notes on how to do this online and it is very important and should be done consistently. This way you will not lose a lot of work should you have to turn off power or restart your computer due to a crash (or a power failure!). Losing work is never fun and can be avoided by a little preventive maintenance.

Best Wishes
