Why do Computers Fail or Struggle with Issues?

Computers are intricate machines comprising hardware, software, and drivers. The hardware is from different companies and the software runs on complicated coding and several drivers are used. Fortunately, they run correctly and steadily, but can sometimes encounter a glitch. 

The majority of dilemmas are due to software program error, which is fixed through an updated version [software code patch]. Developers release patches often, which you can download via the program or from the internet.

Most companies sign up for a contract with some reliable computer repair business in order to ensure business continuity. These service providers offer complete IT support like computer setup, software installations, system upgrades, updates, etc. They also offer backup strategies to make sure that the business operations do not get interrupted due to system failures.

Reasons why computers tend to struggle or fail

  • Dust & dirt accumulation
  • Outdated software, drivers, operating system
  • Data corruption
  • ESD [static]
  • Heat
  • Overclocking
  • Hardware incompatibility
  • Electrical interference
  • Hardware failure
  • Short circuit
  • Programming error
  • Improper drivers
  • User error
  • Malicious user
  • Spillage of liquid or water
  • Lack of resources
  • Power spike, outage, or brownout
  • Weather
  • Wear & tear

Causes of hardware failure

Hardware can fail and stop the computer from working. Some reasons why hardware components can fail are given below.

Over or underpowered

Too little or too much power supply is controlled by a surge protector. In case, your computer has no surge protector then it is at risk of receiving too much power. The hardware needs protection from an uninterrupted power supply [UPS] or it will be in danger.


A desktop computer is not designed for frequent movements. It can loosen up the memory, expansion cards, or the cables within. Any cable or card is not connected firmly, so can cause computer failure. Abnormal movements even in mobile devices have triggered component damage. 

Bad capacitor

Blown, leaking, or defective capacitors can trigger the hardware component not to work.

Weak solder

ICs, Inductors, Capacitors, and other components are soldered to the circuit board. If there is poor soldering then the components can loosen up due to heat or get chipped away and create a bad connection forcing the device to fail to work.

Heat & temperature fluctuations

Overheating due to weather or fan stopped to work can damage hardware device. Extreme environments cause sudden fluctuations in the temperature that causes condensation between cold and hot. Moisture damages the electronics or loosens the components over time because of expansion and contraction. 

Wear & tear

Computers have moving parts like hard drives, fans, and heat sinks. Over time, these experience deterioration and ultimately fail.

Bad IC 

Hardware is controlled by a circuit board. It starts to perform poorly because of mentioned reasons. If the circuit board or IC becomes defective, then it prevents components to communicate. 

User error

The computer installation or cable connection can be improper, which prevents the device from functioning. It can possibly damage your computer. When you work with electronic hardware, it is crucial to be cautious in protecting it from electrostatic discharge [ESD]. 

Ensure that your software has all the latest updates. Keep your computer clean from dust and debris. Even keep liquids and water away from the computer keyboard and laptops.
