A PC that won’t boot up can give you only two sorts of reactions: you expected that to happen or you’re blaming destiny because your computer just decided to die on you when you have important files that you must access ASAP.

Whatever your reaction is, it’s extremely challenging and worrying when the computer suddenly won’t start up anymore. But, fear not.

This guide provided by Budget Computers & Mobiles should get you through.

Check the Power Source

Unless your computer fell from a height or has had liquid spilled on it , it should open without fail. Before you panic, make sure the power Supply Unit (PSU) is the problem or perhaps a loose wire. Given the extensive use of PCs and laptops, the power sockets or even a fuse might die out occasionally. Connect another appliance or device that you know works to see if the socket is the problem.  Once you’ve confirmed the socket isn’t the problem, connect your notebook or computer to another power supply and see if it works there.

Inspect the Parts

Once you confirmed that the power outlet isn’t the problem, diagnose the following:


  • Power charger/adaptor—double-check the power supply or charger for your laptop. This is the rectangular block along the plug and power connector. If you’re not using the original manufacturer’s adaptor, test if the plug itself already gave out (replacements tend to give out prematurely).
  • Plug fuse—there is a fuse inside the plug. Check the casing of the plug to see its condition. When there are signs of blowing out or black markings, it might be time to find a replacement.
  • Wiring—check for loose wiring at both ends of the power plug. You might also want to check if the ends are still connected. If you find any problems with the wirings, it’s better to change the whole unit to prevent short-circuits.


  • Power Supply Unit (PSU)—PCs have an adaptor too, which is usually larger than a laptop’s. Check for the fuse to see if it’s blown.
  • Boot up buttons—compared to laptops, the boot up or power buttons in the PC’s CPU statistically fail more often. So if the LED light indicator is on, it might be circuitry problems.
  • Monitor—sometimes, people forget to press the separate power button of the monitor, so when booting up, the screen still appears blank. Check if the monitors are on.

Look for Glitches

Aside from the common causes of boot up failures, there are also some unrelated factors that affect the boot up option on your PC. Consider performing the following at the onset of a failed start-up:

  • Remove USB drive or memory cards or any connected non-essential external device
  • Insert your recovery disk to fix any registry, hardware and booting issues
  • If the screen only previews for a short time, try going into safe mode

Boot up problems don’t just happen. It may be due to natural wear and tear or some combination of hardware and software malfunction. But, the key lies in correctly identifying what’s causing the problem. If you can’t find or figure out the problem yourself, its probably best to bring it to a laptop repair specialist or a computer repair shop to properly diagnose and fix your issue if possible
