Computer Desktop CPU Fans

A CPU or central processing unit is the main part of a computer desktop. There are many components in a computer desktop like the motherboard, hard drive, processor, and other essential parts that make up a functional computer. The fan is a very important for a computer desktop because it keeps the computer cool while it is working.

If the fan is not working then the computer will automatically shut down because it is overheating. Using a computer without a fan can permanently damage the components and soon it will not turn on at all. Most people who use computers are not computer technicians. Many people like myself use the computers for business, education, and entertainment. When something goes wrong with the computer, people either send it to a computer technician, or in extreme cases, trash the current computer that is not working and buy a new one. Either way, fixing the problem is expensive.

One of the cheapest ways is to fix the problem yourself. Fixing a computer yourself is scary, especially if you don't know how. Most of the components that make up the computer are actually practical to fix because the components are easy to install. For example: the fan in a typical computer desktop is easy to plug-in. Aside from viruses and physical accidents, overheating due to faulty or broken fans is also a major problem in computer operations.

It is very frustrating when you are doing something very important on your computer and it fails because it overheated. If you are going to fix or replace the CPU fan yourself it would be best if you can find the plans or instructions to help guide you. You can either go online or go to the library and look for the company that built your computer. Generally most computer desktops are the same, but depending on the brand or type, some fans are in different parts of the computer. The CPU fan could be next to the mother board, but in most cases, it is usually located by the power supply. The fan and the power supply are usually in the rear of the computer desktop. Here are a few simple steps in replacing a fan for a typical computer desktop.

1) Before you even start replacing the CPU fan, you must make sure that you have the right fan. Not all fans fit different computer desktops. Each computer company has their own CPU fans for their computers. Always check with a certified store clerk or computer technician to make sure that the fan you are buying is the one for your computer desktop. You can start replacing the fan on your computer desktop once you have the right one.

2) Start by taking off the computer casing. The casing is either screwed or snapped down by a lever. Most casings are held in place by screws, so you will need a screw driver. If the casing has screws, remove the screws, take off the casing and place it on the side. Keep the screws close to the casing.

3) Look for the CPU fan, it is most likely mounted by a few screws next to the mother board and/or the power supply. You must take the screws off to replace the old fan. Most fans are simple plug-in. To remove the old CPU fan, unplug it and then plug-in the new fan. (If you bought a new fan from the computer store, chances are it will come with instructions on how to replace the fan.)

4) Once you have replaced the CPU fan, remount it. Don't put the computer casing on yet you need to check and see if the fan works. Plug in the computer and turn it on. After you have checked if the fan works shut it off and put the casing back on and screw it back in place. That's it! If you are not sure about changing the CPU fan by yourself, you can always get help online through computer or technical forums. You can also check through search engines. There are also technical chat rooms online that can help guide you.

How to Sell and Buy Computer Parts for Profit

You can make a great living selling computers parts. The easy part is actually selling the units. The difficult part of this business is finding a great deal on price. You can make a great living selling salvaged computers and parts. The easy part is actually selling the units. The difficult part of this business is finding a great deal on price. There are thousands of computer parts and accessories all over the web. eBay and Amazon are great places to start. However, my favorite place to buy computers and parts is Property Room. Most all the laptops and desktops on Property Room come without hard drives and power cords. I seem to always find them on Amazon or eBay however. You can get great deals on drives, storage and memory parts. They also offer software on the site and is priced very cheap. It is a police auction site for the public that has great deals on computers, parts, accessories and other items. I can get a good processor on this site very cheap. However, you must read all the descriptions and understand that some of the units are salvaged and missing parts. Take for example-- a laptop selling for 45.00 that needs a hard drive and power cord. I simply go to Amazon.com and buy the power cord for $4 to $15.00. The hard drive can be purchased at Amazon also and eBay. I paid 26.00 for a 40gb hard drive for a HP Compaq nc6220 I purchased from Property Room. I then bought a power cord for 4.00 on Amazon. So I have approx 86.00 in this unit and could sell it for $250.00 easily. I like Amazon for parts because you can choose which company to buy from and most the time shipping is free.

So your selling process in this business is: Buy the computer parts on Property Room. You will need hard drives and power cords which can be purchased on Amazon and eBay.com. I also use Compuvest to buy parts at big discounts. They have clearance specials that can be purchased for almost nothing. You can then buy your software cheap on Amazon for the finished product to sell online. Once you start this process your business will grow and you will be able to stock more parts and sell more units online at large profit.

I have given you some ideas about where to buy computers parts etc. You will understand a little more as you grow your business.

Computer Repair: Why Is Your Computer Running Slower Than Normal?

If you have a computer you are not unfamiliar to computer repairs. It is inevitable that your computer will eventually run slow or not at all especially if you are a novice to technology which lets admit most of us are. One of the biggest reasons clients bring their computers in is that they are slower than when they first purchased them. They always want to know who or what is to blame for this. No one wants to hear it but the problem your computer may be running slower than when you purchase it is... YOU!

Maintenance is the key in making sure your computer keeps running at peak performance. Just like your car needs regular oil changes and filter changes your computer needs tune ups to clean up the registry of old programs not in use, updates on spyware and adjustment of settings to insure peak performance. Of course there could be more reasons for the slow down. It is best to take the computer in to a local computer repair firm, as you would your car to a mechanic; to have it thoroughly looked at.

Other reasons that your computer may be having issues running slower than normal could be that your computer has contracted a virus. Trojans, spyware and malware may be the cause of the issue with your computer running slowly. Spyware creates an issue where outsiders have gotten into your computer without you knowing it and start sending out personal data to entities that will take advantage of your system and cause it to run slowly. Even if you have up to date virus protection you can still become infected it just lessens the likelihood. Computer repair in the form of a virus scan and removal are needed and can be done at your local computer repair store. It is also recommended that a tune up be performed on your PC at this time to regain the speed and efficiency of your computer.

You can also inspect your computer and delete files and programs that have been added that are unnecessary. The more files and programs you keep stored on the hard drive of your computer the slower it will run. I recommend having a separate flash drive to store big files such as pictures, word and excel documents. The space adds up quickly. Also, delete any unnecessary short cuts on your desk top they could be causing your computer to run at a snail's pace.

It is important if you have tried all of the similar solutions to look at the computer's hard drive. Run a disk defragmenter which will help optimize how data is stored and then Scandisk to help ensure nothing is actually corrupt within the drive.

Another issue that is common is that the processor is overheating. This is common. You will want to first make sure the cooling system in the computer, the fan, is running. If not it will need to be shut off and taken in for the fan to be replaced. If the fan is running look to make sure a build-up of dust is not causing an issue or that the cabinet the computer is stored in is not blocking the air flow. I have found this happens to me when I am in bed using the laptop and forget about the heat issue. If I set the computer on the blankets the air flow is blocked and the computer will have issues.

Memory, hard drive disk space and conflict in hardware/software are all problems that could also be responsible for the slowing down of your computer. If you have a computer repair check all of the above and there is still issues they will most likely recommend you do an OS reload. Basically this will consist of wiping the computer clean and reloading your operating system. Make sure your data is backed up before doing this. Also, this requires installation of the programs that you run on your computer. This is basically a last resort but it will make your computer like when you first brought it home.

Corrupt files and programs: Corrupt files may also present problems in your system. A corrupt file is sometimes created when there is interruption when you try to

The quickest way to find a problem is to always start with the most obvious cause. Generally speaking, hardware malfunctions are usually the most obvious and easiest to fix. Secondly, check if there is a pattern for the "crashes", especially if you have encountered several "crashes" before. For example, you may find that your computer tends to crash when you are watching movies; this may indicate a problem with your graphics card drivers.

A computer crash is a condition where a computer's application and or operating system ceases to function properly and exists, due to a malfunction in the execution of the machine instruction.

Building a Computer? Don't Be Scared

Times being what they are, you may be thinking of building your own computer, but is it worth it? Is it worth the chance of your new build starting on fire after you've put it all together and hit the power button for the first time?

Six years ago that's what happened to me. Well, it wasn't really a fire, but it was close enough. Let me start from the beginning. I was a gamer, but a gaming computer starved gamer. I needed something that could fulfill my gaming needs. I needed to log on to my favorite mmorpg and hunt down some newbs without chopping and crashing to the desktop. So I decided that building my own computer would be a good idea. I did the research and bought the parts. I even bought one extra part, a motherboard. I had forgotten to take it out of the online shopping cart before clicking the final "submit order" button. What a lucky break, but I'll get to that later.

After submitting my order, about a week later my parts arrived. The site of my new gaming PC in its shiny new boxes strewn all over the floor was truly something to behold, but alas, it was also frightening. Frightening because I had just spent around $2500 on something I really had no idea how to assemble. I thought it would be like hooking up a VCR, there's only one way to do it, right?

Let me give you a little more background information here, my roommate had ordered the exact same computer and his parts arrived along with mine.

Anyway, we unpacked all of my parts and started to build the computer at about 9 p.m. It was winter, so it was dark, but our moods were that of life lit by a roaring fire to achieve gaming greatness. By 3 a.m. my computer was fully assembled. We had went through the heart pounding process of snapping the RAM into place and figuring out exactly what stand-offs were. Even more frightening was the process of installing the CPU and then pressing with the force of 100 men to snap the CPU fan into place. But, it was all done, or was it? You see, there was this one extra cord, I believe it said something about HDMI sound on it.

Every cord we had plugged in had been either clearly labeled or clearly obvious as to where it needed to go, but there was no clear spot for this one. I was going to leave it unplugged as I just thought it was an extra random thing that I didn't really need, but my friend found a spot where it would fit, and it actually did seem like a good spot for it. I reluctantly plugged it in. Finally, we were done.

I hooked up the keyboard, mouse and monitor and prepared to hit the power button for the first time. The anticipation was killing me. In fact, it had me so frightened that I had one hand on the power cord on the back of the computer while the other was getting ready to push the power button.

I then pushed the button and within half a second my other hand had pulled the power cord out of the back of the computer. There was something about the smoke that had come rolling off the motherboard that made me pull the cord. Maybe because smoke means fire? I'll never be sure.

After spending a combined total of $5000, we had just lit our first attempt at building a computer on fire. Let's just say there was a little tension in the room. Luckily I had that spare motherboard.

What followed was the quickest build teardown and subsequent assembly I have ever done. We were so overwhelmed with madness that we didn't really care what happened next. Within an hour we had my new computer fired up and running. That first site of Windows popping up on the new monitor was amazing. It was one of the best feelings I've ever had. It was all worth it.

Times being what they are, you might not be able to order a spare motherboard. But don't fret, just remember the moral of the story, well, I'll let you figure it out.

Notebook Computer Reviews: Read First or Regret Later

The history of the computer can be traced back to the year 1642, when French mathematician and scientist Blaise Pascal invented the Pascaline. Back then, it was considered a revolutionary invention, but it only featured one function, which is to do addition and nothing else. Thanks to the rapid development of technology, computers today can do lots of different things and they are available in many different sizes. Nowadays, almost everyone has a laptop or notebook computer. However, a lot of people can't tell the difference between a laptop and a notebook.

A notebook is slightly different from a laptop in some aspects. It is usually equipped with a long life battery that can last up to 4 or 5 hours, so you can use it for a longer period of time. It is also very light and thin. Generally a notebook computer has a 12-14 inch TFT screen and it does not have internal DVD/CD drivers. However, it usually comes with an external DVD driver. It is also generally more expensive than a laptop; it gets more expensive if it is thinner and lighter. There are so many brands that offer various models of notebooks with different storage capacities and processor speeds. If you would like to find one that suits your needs, it is always better to read notebook computer reviews from reliable sources. Thus, it will give you an insight into whether the particular notebook is what you need.

On the other hand, a laptop computer is a type of portable computer that is generally bigger and heavier than a notebook computer. It only has 2-3 hours of battery life and it features a 14-17 inch widescreen TFT display. The good thing about laptop compared to notebook is that it comes with an internal DVD-ROM or DVD-RW driver, so you do not need to purchase an external driver to play your movie DVDs. Furthermore, a laptop is also upgradeable. You can easily replace your old RAM card with a new and better one to improve the performance of your laptop.

These days, you can even buy a netbook computer. A netbook is much smaller and lighter than a notebook and laptop. The battery can last up to 8 hours and it comes with a 8-10 inch screen. Since it is equipped with a less powerful processor, you can't really use a netbook computer for multitasking or for entertainment purposes. It generally doesn't come with an internal or external DVD driver, so you will need to purchase a separate external unit. This portable computer is recommended for those who are always on the go and need access to a computer frequently.

Portable computer surely makes life easier. Notebook or laptop computer is recommended for entertainment purposes whilst netbook computer is ideal for people who are always on the go.
