PC Repair Notes
Transcript of PC Repair Notes
Computer hardware: Before entering the field, students should have a thorough understanding of the various interlocking parts of a computer and how they function together. Certain courses may require students to take computers apart and re-assemble them to demonstrate their intimate familiarity with PC hardware.
Troubleshooting: Students learn how to locate and identify the sources of hardware problems, including running tests and various other fault-finding techniques. Students will also learn how to take action to correct these problems, including replacing or upgrading troublesome parts and making repairs.
Software basics: Although students will typically focus on tackling hardware issues, they should also be prepared to face software problems in their working lives, as they should expect clients to reach out to them with any number of PC problems. These courses teach students how to identify and remove computer viruses and handle other software malfunctions.
Since PC hardware training courses are usually meant to prepare students directly for careers as computer technicians, all of the skills they acquire in these courses can be directly applicable to their future careers.
Hardware-related challenges, troubleshooting and repair techniques will be similar to the ones they'll encounter on the job, if they choose to become technicians. However, these skills can also be useful in other careers, should students choose not to follow the technician route.
The intimate knowledge of PC hardware students should acquire in these courses is the same they would need to pursue careers as computer hardware engineers, the people who work to create and design that hardware in the first place. Knowledge of computer hardware is also extremely helpful for students who pursue careers as computer software technicians, network or systems administrators, or other IT support roles.
The mother board is very important and controls everything in the PC.
You can find jobs like PC repairing in Microsoft. Their always looking for technicians to make or fix their computers,but applications vary in 10 months;depending on the company or the stocks invested.
Bluetooth: Not a physical port, but bluetooth is how many wireless peripherals like mice, keyboards or speakers can connect to your device.
SD card readers: Cameras, e-readers and even tablets commonly store data on SD cards.
Depending on specific uses you have in mind for your device, you might also want to pay close attention to the availability and quality of other features such as optical drive to read and write CDs and DVDS, speakers, onboard camera, graphics card and wireless network card.
Install antivirus security software and set up a regular sweep. Your computer may have come with a pre-installed antivirus system, but be sure you have one and it is set up to regularly search for and destroy malware on your machine. There are plenty of quality free programs such as AVG, Avast or Avira available if you need them, but no matter what, it is vital to protect your computer against viruses.
Consistently back up stored data and create restore points. Be prepared for the worst by regularly backing up your files on the hard drive or an external hard drive to be extra safe.
Keep your system and programs updated. Software developers regularly put out updates for everything from your operating system to programs you use regularly. These updates make sure your software is running top notch, but updates also regularly plug security holes so you will want to install updates as soon as you are notified of them to protect yourself against malicious viruses and spyware.
Uninstall unused programs and files and regularly defragment your hard drive to keep your computer from slowing down. The more free space your computer has on the hard drive, the faster it will run so if you have old files you don’t need or old programs you don’t use, clear them out.
Practice safe browsing habits to avoid viruses and phishing scams. Much of the malicious software that wrecks computers finds its way to your device through your own unknowing clicking.
Clean out dust and grime that accumulates outside and inside the machine. Built up dust can cause overheating and is to blame for lots of computer breakdowns. This is simple to avoid by regularly using a small vacuum to remove dust and then spray with compressed canned air. For tower-style desktops, you will want to remove the side panel to carefully clear the dust inside the tower every three to six months for optimum performance.
Plug your desktop into a surge protector. Electric storms can irreparably damage sensitive components inside your computer. The simplest way to protect it from power surges is to plug it into a surge protector.
Many customers often forget to ask about the hourly rate and then find themselves in the awkward position of having to pay a lot more than they expected for an incredibly short repair. Even though you might be upset and eager to get your computer up and running again, make sure to discuss expenses in advance.
A Technician;Today, could make $13.21 per hour depending on the kind of problem it is. In a year, Technicians make approximately $57,960 or more.
PC repairing is a great job, but people a hack and steal money, data, and precious privacy.
PC repair plays an important role in today's society. PC repairing can help people with many complications to their computer for money or sometimes for free. Society is getting smarter and faster everyday, It's better that we drive technology than keep up with it.

While a dead PC will either normally be a bad power supply or bad motherboard, the next easiest thing to troubleshoot is the case.
Power supplies can fail without warning. The worse part is, they can partially fail.
A power supply will tend to fail before anything else, as they take the most abuse. They are the front line when a power surge or brown out occurs.
The motherboard is the hardest thing to diagnose and replace.
If your motherboard is proven to be bad, it must be removed from the case and replaced.
There’s a lot of stuff plugged into the motherboard, such as the CPU, RAM, PCI cards, Video Cards, hard drives, CD / DVD drives, power supply and fans.
Repairing your own computer can be great fun, and can save you loads of time and money.
A charged cathode ray tube stores a lethal voltage that can electrocute you.
The vacuum tube itself can implode if broken or punctured, posing another level of risk to you.
The power supply is mounted in the inside corner of the case, and can be easily identified by the bundles of colored wires that are protruding from it.
The power supply should be regarded as a ‘black box’; when it fails, replace it.
A catastrophic failure will damage the component beyond use, while an upset failure can degrade the performance of the component, thus making the problem more difficult to detect.
To protect your computer against ESD damage, you need to ground yourself before touching any electronic components, such as the hard drive, memory modules, processor, motherboard, or expansion cards.
During a repair or upgrade procedure, components that you remove from the computer should be placed in anti-static, or static shielding bags to protect them against the effect of ESD.
Here’s what you need to do to reduce the risk of ESD damage:
Wear a ground bracelet
As you remove components from the computer, store them in anti-static bags
Remove all jewelry
Wear natural rather than synthetic clothing
If you have long hair, tie it back
Work on hard floors rather than carpeted surfaces
Many computer problems can be diagnosed and repaired with just a few essential tools, which can be easily purchased as a kit at your local computer store.
The chip extractor tool is one that you will rarely, if ever use, since modern computers incorporate very few field-replaceable integrated circuit (IC) chips.
The tweezers and spring-loaded extractor tool are handy for picking up debris or a fallen screw from a tight spot.
Various sized screwdrivers are provided to remove internal modules or to remove the case cover itself. Some case covers are designed to be removed without any tools at all.
There are a few other tools that would add to the convenience of your repair procedure:
Small container or cup to hold loose screws
Needle nose pliers
One of your most essential tools for troubleshooting your computer is a bootable rescue disk. This disk will allow for what is called a ‘clean boot’ – that is, any extraneous drivers and software that are normally loaded at startup will not be loaded.
Regardless of media type, an emergency boot disk is usually included with your purchased system.
The bottom line is that you need an alternative way of booting your computer if you are not able to boot to the hard drive.
