As a computer user, you should have a basic knowledge of how computer repairing and troubleshooting are done because problems may occur at any time. Once you read the entire post, then you’ll be able to fix your computer troubleshooting even if no spare parts region may not be able to fix it. Even a repair center won’t be able to charge you extra by claiming some extra problem that is not their Computer repair without seeking professional IT help is possible for any computer two types of problems showing hardware or software issue so here you need to understand the exact reason behind it. Let’s Explain Hardware and Software.

Good news for Only Guwahati_ans we provide Computer repair doorstep service.

What is Hardware?

Hardware is any part of the computer you can touch and feel like any peripheral equipment more details

Quite simply, computer hardware is the physical components that a computer system requires to function. It encompasses everything within a System, including the-

• Computer repair
• Computer case,
• SMPS (switched-mode power supply)
• Motherboard
• Processor
• RAM
• Hard-drive
• Graphics card
• Monitor Etc ..

Let’s see which device or components what’s type works and what kind of problem does it show how can we solve this.

Note: Before doing anything the first step remove (Unplug) the CPU Power cable.

Computer case

The computer case sometimes called a Cabinet, is a box-like case that stores all the Devices or components that make up your computer or system unit Computer case is made up of metal or plastic and one site glass. it protects the internal electronic components from damage.

• SMPS (switched-mode power supply)

SMPS is a system power supply unit that stands for switched Mode Power Supply. It is an electronic device or module that comprises a combination of inductors, capacitors, and semiconductor devices like diodes and Mosfet’s

Quite simply incoming electricity into proper voltage and supplies it to the other parts inside the CPU box.

Let’s see SMPS fault and finding

98% Computer repair  SMPS showing problem ON issue power switch push but Won’t Turn On. 

  2% SMPS showing another issue.   

 Solution 

              Find the 24 pin connector from your SMPS ( it is the bigger connector from SPMS)

Find out the green and black wire, take a 4 inc wire clip, and bent it in the shape of the “U” shape. Insert one end of the bent wire clip into the green terminal and the other end to the black terminal. Turn on the SMPS with the wire inserted the SMPS should be running fan now your SMPS is in working condition. your SMPS didn’t turn ON or no moving SMPS cooling fan. your SMPS might be faulty.

Replace SMPS, install new SMPS.

• Motherboard

A motherboard is the main printed circuit board found main circuit board in general-purpose computers and other expandable systems. It allocates power and allows communication to and between the Processor, RAM, Graphics card, and all other computer hardware components or devices.

  Let’s see Motherboard Troubleshooting as your computer ages Dust will build up inside of it. Dust can cause your computer to overheat and malfunction. It can even short circuit and damage your motherboard.

                       Fast step turns off and unplugs your computer power cable, disconnect all communication hardware components or devices. The next step cleans Your motherboard, use A soft-tipped paintbrush or as possible use compressed air to remove dust, after cleaning your motherboard re-assemble or install connects all components and cable, and then turn on your system I hope to solve your issue.  

Motherboard Two common major problem 

• Motherboard dead  (note: fast check SMPS try to new SMPS)
• Motherboard no Display  (note: fast check install new RAM)

Motherboard fault and finding you have to do is Chip level repairing Does not cover a hardware course, as possible to go your nearest chip level repairing center take the only motherboard no need full CPU and try to your motherboard repair  

I recommend you have a budget bay a new motherboard its a best option   

 Note- The direct solution to replace your motherboard install a new motherboard

• Processor (CPU)

CPU- Central Processing Unit often called a Processor is known as the brain of your computer and laptop. The processor significantly makes an impact on overall computing power and manages most of the computer’s operations. 

Quite simply Processor is a processing unit

Currently, Intel and AMD are only two major processer chip manufacturers.

  Let’s see Processor fault and finding

• The processor immediately overheating, no display or On but immediately Off.
• Processor no heating. 
• Beeping sound.
• Undue stress or over-clocking.

This type of problem installs a new processor, there is no way to repair the processer.  I hope to solve your problem.

• RAM ( Random Access memory)

Memory plays a very important role in the computer. Memory holds both the data that need to be processed, as well as the data that have already been processed. This memory is a temporary storage place for data instruction and information. when the switched on to start a computer certain operating system files load from a storage device such as a hard disk into RAM, the processor (CPU) interprets the data while it is in RAM. 

Quite simply RAM is Display running memory

Let’s see RAM fault and finding 

• CPU ON  but No Display ( monitor show nothing “ no signal”)
• Infamous Blue screen of Death
• Declining PC Performance
• Install a new program failed
• Random Restart
• Computer Beep 
• RAM size missing

Solution

This type of RAM issue solves the first step to remove your RAM and clean the golden color pin you can also use an eraser or cotton cloth after cleaning reinserts the same slot or another slot RAM and Turn on your system. I hope this solves your problem. this Problem is a common problem for Computer repair

The last solution inserts a new RAM.

• Hard-disk  (hard-drive)

hard-disk is a storage device in which computer stores data. Hard-disk is also called a hard drive. Two general types of hard drives (HDD) that use one or more rotating discs rely on magnetic storage, and solid-state drive (SSD) which have no moving mechanical parts use flash memory as USB flash drives SSD super fast hard-drive.

Hard drive showing problem 

• A Hard disk drive failure( boot drive failed) hard disk drive malfunction and the stored cannot be accessed.
• Hard disk error
• HDD hard drive( common Problem) Clicking, grinding sound.
• Extremely slow
• Operating system unable to boot

Hard drive test software available, all Computer repair centers use software list.

• ScanDisk
• Chkdsk
• TestDisk etc

I suggest replacing it and installing a new Hard Drive.

Graphics card

The Graphics card is a circuit board that plugs into an expansion slot of the motherboard inside the computer. It translates instructions from the computer to a form that the monitor can understand. A Graphics card is also called a Video card.

A VGA or HDMI cable connects the monitor to the Graphics card in the computer. You only buy additional Graphics cards if you want to high-end Graphics or play a game that needs more graphics. 

Let’s see the Graphics card  fault and finding 

Graphics card starts going bad warning- Stuttering your display image or a high graphics program, you might see visual stuttering/freezing on the screen sometimes your computer restart, after a restart your computer screen the same time running will go back to normal if you have a faulty Graphics card.

Solution

                This type of Graphics card issue, fast step remove your Graphics card and clean golden color pin you can also use an eraser or cotton cloth, after clean carefully open GPU heat sink a then Apply thermal paste Re-insert Graphics card and turn on your CPU test it.

I hope to solve your problem.

                       Your problem is same condition as the last solution to replace your Graphics card install a new one.  

• Monitor    

The term monitor usually refers to a video display. The monitor is attached to the video adaptor by a cable. The monitor looks like a television screen. Whatever you type on the keyboard, comes on the monitor. The output device displays information in pictorial form.

The most common sizes are 15.5”, 18.5”, 20’’, 24’’ inches.

       The size of the monitor depends upon its use. A large monitor allows you to view more information on the screen at once.
