The Random Hang-up Problem


You may have experienced having your computer intermittently hangs-up, or may re-boot itself for no apparent reason. This can be annoying, and can mean you have lost valuable work that you we in the process of creating.
If this has happened once, then your chances of explaining the cause are remote in the extreme. If you find it happening regularly, then it is clearly in your interest to find and fix the problem.
There are a few things you can check for yourself that may save you a trip to the repair shop.
With most modern computers, the system comes with built in circuitry to monitor the state of the computer. One of the checks built into your system is to test the operating temperature. The computer may shut down if this moves outside the desirable operating range.
For your system to run at the correct operating temperature it is important that air circulates freely in and around the case. If you have the computer case installed inside an enclosure, then this may be the first thing to consider changing. Similarly, I have seen computers covered with books, manuals and paper documents. These again can hinder air circulation, and these items should be removed. Take a look at the slotted vents in the sides of the case. These slots can become blocked by an accumulation of dust. Because the computer is usually always drawing some power, it has a constant electrostatic charge. A computer is second only to a vacuum cleaner in its ability to suck in dust and fluff.
Taking the cover of the case will also show the dust build-up inside the computer. Be careful removing dust accumulations from internal components. This is probably best done with a soft artist’s brush or an aerosol can of compressed air.
Next, take a look at the internal cooling fans. Modern computer usually have a cooling fan perched on top of the processor. This fan should be clear of dust, and running freely, without obvious scraping noises, when the computer is operating. It is OK to start the computer with the case cover removed, just be careful not to poke things into the various components. There will also be a cooling fan inside or attached to the power supply. This again should be free of dust and running freely. Some computers may also have an additional case fan. This will be screwed on over one of the slotted case vents, and typically be running from a cable connected to the mother board. Not all machines have a separate case fan, but if it is there, it is there for a reason. Apply the same checks to this fan.
If you have identified faults with your cooling fans, this may require a trip to your local repair shop. The repair technician may also suggest that the CPU heat sink be removed and re-placed with fresh heat transfer compound, which is a straightforward job for an experienced repairer.

Become Your Own PC Repairer


If you are like me, you have probably owned quite a few personal computers. You are sure to have had the occasional problem, and rushed the machine off to the repair shop. At the time, the cost of repairs may have seemed a bit high in proportion to the original cost of the machine, and you might not have been quite sure what was actually done.
You can learn to do your own diagnosis and repair work. It is worth while knowing what is going on inside the box, even if you do not do the work yourself. With a good understanding of the likely causes of the hardware problems, you can be a lot more confident that the repairs carried out were reasonable and necessary.
To begin with, a good source of technical information is necessary. You can always ask at your local electronics shop, but if you really don’t know what you are talking about, the embarrassment can be a big turn off. There is an excellent book available called ‘Upgrading and Repairing PCs’ written by Scott Mueller. This is the most complete and most readable ‘how-to’ book I have found, and if you only buy one book on the subject, Scott’s is the one to get you hands on.
The next step is to choose a few projects to get familiar with the hardware. The best way to begin building up your skills is to pull a computer completely apart, and then put it back together. If it still works after that, then you have made a pretty good start. At this stage, you may be thinking ‘hang on a minute, I paid a lot of money for my system - No way am I going to risk messing with that baby’.
No, as a beginner, you definitely should not. You can get hold of some old computers to tear apart and rebuild. Old computers are seen as worthless, and you will find Pentium 1 and 2 machines being discarded as rubbish, even though they are still in good working order. Even a Pentium 3 can be bought very cheaply, and most of these are pretty good performers. A word of warning – be careful how widely you spread the news of you new interest in old computers. You will be surprised how many 486s and older are sitting in cartons in garages and basements; your friends and family will really be delighted to give you an amazing collection of electronic junk.
Get familiar with the various parts, and how they fit together. Learn to identify the different styles of processor chip, RAM, disk drives and other components.
As always, safety is paramount. The computer components themselves operate at low voltages, but you still have the mains strength voltage coming into the back of the computer. Always power off and unplug when you are working on the computer, and be suspicious of any signs of overheating or of burning smells. Enjoy your tinkering.

Cell phones, do you really want to be available all the time?

Do you really want to be available for anyone and everyone on a 24/7 basis?  What do I mean?  A famous person once said that the more available you make yourself; the more available everyone will expect you to be. People will actually be annoyed if you are not instantly and constantly available rather than being pleased when you do call. People expecting you to be available all the time may be annoying.  Cell phone calls follow you everywhere you are including your bathroom.  Even during nighttime when you want to rest, cell phones continue to ring and annoy you.  If it is important, no problem but if it is very menial, why you need to be bothered so late.

Today in this modern society, we live in and the proliferation of cell phones we see people talking anywhere and everywhere.  If used for business, this may prove to be very effective and worthy.  However, for very menial issues being bothered in your sleep and even during your bathroom time may be quite annoying if not outright disgusting.  However, if you make yourself available all the time, you created your own nightmare.

Cell phone etiquette is getting to be a forgotten concept.  You will see people talking on the phone loudly and disturbs people nearby in restaurants and even in offices.  I am sure by now, once or twice in a meeting you will notice that when a cell phone rings, almost everyone around will immediately look for their cell phones.  If you were the one talking, and then the person in front of you talks on his phone, how would you feel?  I am sure you will feel belittled and ignored.  Rude practice, and should be changed.

It may help people who use cell phones to follow certain degree of etiquette with respect to the use of cell phones specially in places where you may seem rude if you use or even when your cell phone rings.

When you are in a place of worship, it may be necessary to leave your cell phone in the house or at least turn it off if you do not want to be away with it.  This is because ringing cell phone will not just disturb you while you pray it will also disturb others.  You do not need to show off your expensive gadget in a place of worship.  

During meetings, please turn off your cell phone; it is rude to have your phone ringing while somebody speaks.  Disruption may cause problems especially when the meeting tackles extremely important issues.  However, if you are waiting for terribly important call, you may use the vibrate mode of your cell phone to alert you when a call is in-coming and leave the meeting if you need to answer the call.  You may also inform the possible caller that you are in a meeting and that you cannot be disturbed.

When traveling and if you are on-board an aircraft, you will be required to turn off your phone.  This is because electronics devices may interfere with the aircraft’s avionics.  Thus, it is a requirement to turn of your phone for safety reasons.  However, for extremely long flights, airline companies allow cell phone usage at a certain time, if you really need to make a phone call, use this time allotted if necessary.

Cell phone have become to be a necessity nowadays, that is why most people use it and cell phone manufacturers have continuously develop different usage and functions for this very small gadget. Be globally competitive, but you should understand that being rude is not part of modernity.  Follow certain degree of etiquette; this will be very helpful to you and your business.
