Intel has produced the first quad-core processor known as the Quad-Core Intel® Xeon® Processor 5300 series. This processor multiplies your performance, energy-efficiency, and reliability. In addition, the quad-core processors helps to decrease the total cost of ownership of a server “with lower power consumption, increased uptime, and a reduced footprint without sacrificing the record-breaking performance you expect from Intel”, according to Intel. What next? Penta-core processors? At the rate Intel is going anything is possible.

Intel claims that persons who use the Quad-Core Intel® Xeon® Processor 5300 series will “experience up to 50 percent greater performance than industry-leading Dual-Core Xeon processor in the same power envelope and up to 150 percent greater performance than the competition with Quad-Core Intel Xeon processor 5300 series. Translating into greater performance with less cooling challenges, these servers enable you to run more applications with a smaller footprint, giving you revolutionary ways to achieve more with less.” This amazes me because the norm is that the faster the processor is the more cooling it would need. My computer uses a 1.7 GHz AMD processor and I have to open the case at times to keep it cool! Maybe I need to get a motherboard that can take the quad-core cpu and upgrade my PC.

Intel has made processors over the years that have been quite efficient and are being used in thousands of computers all over the world. Their technology was the one that I was exposed to at the start and I am still impressed with them, though my present cpu is not Intel-based. Nonetheless, Intel’s growing hold on the processor market is underlined by the fact that they are innovative with their creations and always seem to introduce products that people will want. Not only that, the higher the technology is the better the cooling ability.

Lastly, here is what Intel has to say about itself, which is true: “Intel has revolutionized the general-purpose server, providing the performance you need to transform your data center from a support mechanism into an engine of success.” Gotta build me a quad-core server soon.

There are times when we hear ‘funny‘ sounds in our computers. More often than not it is the sound of the various fans at work keeping components cool. The sounds are normally low decibel sounds, i.e. you barely hear them while the computer is running. If you don’t hear them any at all, they may be the ‘extra quiet’ type of fans. In any case, always check to ensure that they are in fact spinning and operational.

If, however, you realize that the sounds seem to suddenly become high pitched, i.e. louder than usual, any or all of the following could be a factor:

1. The Motherboard Fan needs to be changed
2. The Chassis Fan is defective and needs to be replaced
3. The Power Supply Fan is in need of replacing

Try to locate the source of the noise. When you discover which fan it is, try to get a replacement quickly. Improper cooling can destroy sensitive components in the PC. Read my previous post on The Burning PC which shows what can happen if improper cooling takes place and what you can do to prevent and remedy the situation.

But there are times when the fans are perfectly okay. So where could the sound be coming from? The next logical device would be the hard drive (hard disk). When a hard drive starts making out-of-the-norm loud vibrating sounds, it could be an indication that it is about to fail. To see if this is the case, perform a simple drive check. If it is defective, seek a replacement as soon as possible and also backup your data.

There are various types of power cords used on electrical amd electronic equipment. The end that is plugged into the surface outlet is usuall a two or three pin plug (third pin for grounding). The other end that is plugged into the equipment is also usually a two or three pin connection. Some have four or more, depending on the equipment itself. As for computers, the plug end of the power cord has three pins while the other end also has three holes.

To differentiate between the power cord used on the monitor and on the CPU, the one for the CPU is usually thicker. The general reason for this is that the CPU pulls more power than the monitor and thus the thicker cord is less likely to melt or catch afire. This is the convention that dictates the size cords used on many equipment. The more current it pulls, the thicker the power cord. This is despite the voltage used, whether 110V or 220V.

Power cords must be regularly inspected for cracks or tears. There are times when the cord might be under some level of strain which eventually leads to its deterioration over time. If at any time you notice when the power cord is moved and the equipment is on it suddenly loses power, this is a sign to change it. This is very importatnt as the shorting out of the power cord can result in fire and eventual damage to the computer.

Have you ever been doing some work on your computer and then it just suddenly shut off by itself? All you see happening after is your power light blinking. What does that signify? Well, believe it or not, the Power Supply in PC’s are designed to shut your computer off if it becomes too hot. I can attest to that as it has happened to me a few times. So, you may wonder what causes that to happen, and how can it be prevented.

Believe me when I say it is no rocket science trying to figure out why the computer turns itself off – simply put, it is a failsafe, safeguard measure if you will, to prevent damage to your PC hardware. Sometimes when you put your hand on the tower of your machines it is often times hot enough to burn you! That’s what I call “The Burning PC”. The main reason why this happens, though, is more often than not poor ventilation and insufficient cooling. When the air flow through the computer is restricted or is not moving rapidly enough, the air on the inside tends to warm up pretty fast. Soon, it becomes so hot that the components on the motherboard, along with other hardware, are in jeopardy of ‘spontaneously combusting’. So, it is at this time that the thermostat of the system kicks in and decides to kill your machines power.

Modern motherboards have thermostats that sense air and component temperatues and are intrinsically connected to software that monitor these temperatures and advise the user of any possible problems. They even go as far as telling you if your CPU fan is spinning too slow, or if your Chassis fan is malfunctioning. If things become critical, then a mandatory shutdown is enforced so as to allow the computer to cool sufficiently before allowing it to be turned back on. The system is that smart! Try turning your computer back on immediately after it powers itself off due to overhearting. It ain’t gonna happen!

So now we know why it turns itself off. What can we do to prevent it from happening again?

1. Ensure proper ventilation in the room it is located in.
2. Add more cooling fans to your tower.
3. Use a monitoring software that will warn you of impending trouble.
4. Install a cooling fan on the side of your PC that you use to access the components.
5. Remove the side panel that is used to access the inside of the computer. You may even allow a standing fan to blow air directly onto the motherboard.
6. Use your computer in a room with air conditioning.
7. Do not overload your Power Supply with devices that pull too much current from it. Always try to stick within the power rating of your Power Supply. By this I mean you should not have 3 DVD players, 2 CD players, and countless other PCI devices hooked up to your machine when in fact it can only manage 1 DVD and 1 CD player. Simple logics!
8. Check the state of your cooling fans regularly. They can, and do, go bad eventually. Replace them if necessary.

Well, what a mouthful. I really hope that all this information has helped you. Just remember to keep your computer cool and it will serve you for a long time.

This is part two of how to address common PC problems and the solutions to them. In this round we will talk about problems related to the keyboard and mouse.

Now, these are two integral pieces of hardware that are used to interact with the computer. As of late, many keyboards and mouses (or is it mice?) are wireless, i.e. they use infrared technology to communicate with the computer. Let us consider the problems related to both the wired and wireless keyboards and mouses (once again, or is it mice? – the English language can be so cruel!).

WIRED KEYBOARD

No Response: First of all, check to ensure that the keyboard connection at the back of your PC is not loose or has not fallen out. If either is the case then push it back in place. Press the Caps Lock or Num Lock key to see if the LED for each lights up. If there is still no response, restart your computer. Normally, this tactic should resolve the issue.

If after restart you still have the problem, unplug the keyboard from your PC and shut down the machine. Then re-attach the keyboard to the computer and turn it on. Still no response? If your keyboard uses a Serial Port simply plug it into another Serial Port to see if the problem persists. If it is a PS2 connection, get it checked out. If all else fails, get a new keyboard or have someone check it out for you.

Sticking Keys: Pull your keyboard open and clean out the inside. Many times dirt and moisture accumulate under the keys, so a regular cleaning out under them should prevent the keys from sticking in the future, unless there has been some serious damage done to the keyboard.

Keyboard Error on Machine Bootup: Check to ensure that the keyboard is firmly connected to the port at the back of your computer.

Consistent Beep When Computer Is On: Make sure that there is nothing resting on the keys of the keyboard. A weighty object resting on any key for a prolonged period can cause the computer to start beeping.

Capital Letters Are Typed Even Though Caps Lock Is Off and I am Not Holding Down The Shift Key While Typing: I have found that this generally happens after a few successive cut and paste operations while editing a document. To remedy this problem, hold down the Right SHIFT Key and press the LEFT Mouse Button a few times. Release all keys and start typing again. Everything should be back to normal now.

WIRED MOUSE

No Response: First of all, check to ensure that the mouse connection at the back of your PC is not loose or has not fallen out. If either is the case then push it back in place. If there is still no respose, restart your computer. If it still does not work after restart, disconnect it from the PC while it is on and then shutdown the machine. Reconnect it to the computer and start it up.

A persistent problem would indicate a defective mouse. Seek a replacement as soon as possible.

Erratic Mouse Movements (Cursor Movement Seems Weird): This generally indicates a dirty mouse wheel (does not apply to an optical mouse). To remedy this problem, turn the mouse upside down and unscrew the area around the ball (ususally shows two arrows so you know which direction to turn it). Remove the ball and then take a flat object that is small enough to fit into the space where you took the ball from. Gently scrape off any trace of dirt on the rollers inside the mouse. Be careful not to let the dirt fall into the mouse. If this happens, flip the mouse right side up and knock it out. Then replace the ball and ball lock piece. The mouse should be fine after this.

If the problem recurrs later, repeat the steps I have just outlined.

In part 3 we will look at problems with the Wireless Keyboard and Wireless Mouse.
