Having a computer that won’t turn on or operate at all can be rather frustrating. However, you can frequently locate and fix the issue if you take a methodical approach. This tutorial will take you step-by-step through the process of identifying and fixing hardware and software problems with a non-functional computer.
Initial Inspections
Examine the power source.
Make that the PC is connected to a functional power source.
Look for any indications of damage on the power cord and adapter.
Make sure the laptop’s battery is charged if using one. If at all feasible, try operating the laptop without the battery.
Examine the button for power:
When the computer responds, press the power button to see what happens.
Look for any lights (power indicator, keyboard backlight) and listen for any noises (fans whirring, beeping).
Hardware Evaluation
Examine the connections outside:
Verify that the keyboard, mouse, and monitor—all external devices—are connected correctly.
To check if any external gadgets are the source of the problem, disconnect them altogether.
Track Concerns:
Make that the display is connected correctly and turned on.
To make sure the monitor is operational, try it with a different device.
Examine the monitor’s input source and brightness settings.
Examine Internal Parts:
If at ease, open the rear panel of a laptop or the computer casing on a desktop.
Examine components including RAM, graphics card, and power supply connectors for loose or incorrectly installed parts.
Keep an eye out for any indications of external damage, including burned parts or leaky capacitors.
Simple Troubleshooting Procedures
Reset the power source.
Turn off the power source and remove the power cord from desktop PCs.
For 15 to 20 seconds, press and hold the power button to release any stored energy.
Try turning on the computer again after reconnecting the power cord.
Test Using the Least Amount of Hardware:
Eliminate any unnecessary gear, such as excess RAM sticks, external cards, and supplementary storage drives.
Try starting the computer with the CPU, one RAM stick, primary storage, and power supply as the only components.
Look Up Beep Codes Online:
A lot of motherboards beep to signal different problems.
Consult the manufacturer’s website or the motherboard manual to decipher beep codes and figure out what’s wrong.
Software Diagnostic Examine Access to the BIOS and UEFI:
If the computer turns on but doesn’t boot into the operating system, try pressing the relevant key (typically Del, F2, F10, or Esc) during startup to enter the BIOS/UEFI.
Verify that the primary storage device is detected and that the boot sequence is accurate.
Make Use of a USB Bootable Drive:
Use Windows installation CDs or a Linux distribution to create a bootable USB device.
To ascertain whether the problem is with the hardware or operating system, try booting from the USB drive.
If the USB drive is used to boot up the computer, there can be a problem with the internal storage’s operating system.
Advanced Issue Resolution
Check the RAM:
Utilize a program such as MemTest86 to look for RAM issues.
If more than one RAM stick is installed, test each one separately.
Examine the hard drive.
To look for faults, use the diagnostic tools provided by the hard disk manufacturer.
Keep an ear out for any strange sounds coming from the hard disk, since these can point to a mechanical issue.
Examine the motherboard:
Examine the component for any physical damage, such as burned parts or bulging capacitors.
Make sure the thermal paste is applied appropriately and that the CPU is placed correctly.
Possible Remedies
Change Out Bad Components:
Replace any hard disk, RAM, or power supply that has been found to be malfunctioning.
Think about getting the motherboard or CPU repaired or replaced by an expert.
Reinstall the operating system:
Reinstalling the operating system could help if the machine still won’t start up despite the hardware being in working order.
Before you reinstall, make a backup of any crucial data.
Expert Assistance:

Security and Antivirus:
Installing and updating antivirus software is a good way to guard against malware and other security risks.
In summary
