How to fix my PC that won’t turn on

We are a group of the best computer repair professionals in Calgary, and we’ll quickly fix any startup or boot-related problems in your home or place of business while you watch.

Companies are investing more and more in IT services and equipment as a result of the technology industry’s rapid growth. However, issues arise when computers malfunction and repair specialists must be contacted immediately. These professionals are frequently preferred by the majority of businesses that outsource their IT support to fix broken PCs on the job sites. Some people, however, prefer to have the service provider send the apparatus to a distant computer shop for repair. By inquiring in Nextgen Computer repair Calgary, businesses won’t have to drive around searching for the best repair shops. 

Instead of dealing with the inconvenience of visiting a repair shop, you can now devote all of your time and effort to your task.

We need to do a number of tests to make sure a computer has power when it won’t switch on. The power socket and cables connecting the computer to the power source are the external environment that we need to start with. Then, it’s time to investigate the internal components, such as the power supply (PSU), power switch, and motherboard, once we have confirmed that these are functional.

It may not be simple to diagnose every problem with a computer because they are intricate machines with many parts. Here is our troubleshooting guide that will help you determine the cause of your PC’s inability to turn on and then fix it, rather than testing whether each component is functional.

We are aware of how aggravating it can be, when your computer just won’t start. Because of this, we provide a quick and practical repair solution that will have your computer functioning normally once more in no time.

This guide will show you how to troubleshoot, diagnose, repair, and fix a computer that won’t switch on.

Look for problems with the power supply:

Many of you would find it difficult to believe this, but the most common cause of a computer not starting is that you forgot to switch it on in the first place! Make sure the computer is getting power in the first place as the first step in troubleshooting a dead PC.

When nothing on the screen is displayed and no fans or blinking lights are present, a power problem is probably to blame. Start by checking the power cord’s whole length for rips, dents, and worn-out insulation. If you notice any faults or the power brick smells like burnt plastic, the power cord is probably defective.

Make sure the power switch at the back of your power supply unit is turned on if the AC adapter is working properly but your newly constructed gaming PC won’t post. If it isn’t the problem, check to see if the problem is with your plug socket by plugging it directly into the wall socket.

Following this, your computer’s power supply unit (PSU) is likely to have failed if it won’t turn on. Be sure to verify that you do, in fact, have a dead power supply unit before you replace your power supply. A fried PSU is usually often detectable by an ozone smell or a high-pitched noise coupled with no power in your computer.

Your power supply unit’s input voltage could occasionally be adjusted incorrectly for your nation.

Internal Wiring:

You should inspect your setup for any loose or damaged cables if your new PC is receiving power but still won’t switch on. Poorly linked components may be the cause of your PC not turning on after construction, especially if you are a rookie PC builder. Make sure they fully click in at all times.

If you’re using a prebuilt system, be aware that opening your computer might void your warranty. As a result, try to get advice from your supplier before moving forward.

Security first! Always begin by turning off your computer’s power source before opening it.

Examine the connections between your PSU and the major components after opening the computer case. Check the connections on both sides of your Modular PSU. After that, make sure every component is properly inserted in its corresponding socket. Make that the RAM modules, graphics card, and CPU heatsink are all securely attached. Connect the motherboard cable with 24 pins as well as the CPU cable.

If your computer has integrated graphics instead of a graphics card, you might also try starting it up without any of the other components. Additionally, in case one of your RAM sticks is defective, switch between them. You should contact a buddy for assistance if you don’t feel confident enough to complete this task on your own or you could take it to a repair shop as well. 

Power Button:

You must properly connect the power switch to the motherboard for your computer to turn on when you push the power button. Pushing the power button will have no effect if the two are not linked.

You’ll need to search among the many cords in your case for a two-pin connector, which is typically labelled PWR SW. If you’re unsure, check the manual for your case. Where do you attach the wires from the power button switch once you’ve located it?

The power switch wires must be connected to the motherboard’s power jumpers, which are often found in the bottom-right corner. It is definitely smart to utilise your motherboard handbook because there should be a great diagram that illustrates what goes where since these pins are typically not indicated.

Remove all unnecessary connections:

It’s time to get rid of external gear if none of the aforementioned solutions seem to work. Your PC might not be starting because of one of your peripherals.

Disconnect all of the external hardware from your computer and turn it off. These auxiliary devices include audio systems, joysticks, and flash drives.

Only the keyboard, mouse, and display should be connected when starting your computer (if using a desktop). If it boots up successfully, shut it down, reconnect any peripherals, and then relaunch it. Do this repeatedly until you identify the offender.

Allow the battery to recharge:

Have you recently put your laptop aside and now it won’t switch on? You plugged it into the power outlet after that, but it still won’t turn on.

The battery on your laptop has just fully run out, but don’t worry; it’s probably still fine. Allow your laptop to charge for around 30 minutes before attempting to switch it on once more.

Examine your display:

What’s wrong if my computer seems to be functioning but nothing is shown on the screen?

We receive several calls from customers with identical issues, and in many situations, a screen problem is to blame. Often, just because the screen is black, people assume their computer is off when it isn’t. Simply put, a bad screen could be the reason of your computer’s dysfunction. By making sure the monitor is turned on and connected to the PC, you can rule out a screen issue. Connect your monitor to your dedicated graphics card rather than the motherboard if you have one.

Sometimes, despite having power and a good connection, a monitor won’t display anything because the brightness was unintentionally adjusted to zero.

Have you had your laptop for a number of years only to have it suddenly stop working and refuse to turn on?

Your laptop’s display adapter may be broken if the screen is blank but the power and keyboard keys are lit up. If so, you would need to have a computer professional replace the adapter. By connecting an external monitor to your HDMI or other video output connection, you may quickly check for a defective display adapter.

Check for Viruses or Ransomware:

Is your computer suddenly acting strangely? A ransomware attack could have you as a target. Your computer might not start up properly because ransomware with bad coding has encrypted, deleted, or moved data that it needs to work.

Don’t start your computer from the internal storage drive where Windows is installed if you wish to get rid of unwanted software. Use a bootable USB disc instead. So, how do you use a USB stick to start your Windows 10 computer?

  • Press the key required to enter your BIOS Setup after turning on your computer. Esc, F1, F2, F8, F11, or F12 are frequently used.
  • Find the boot menu once you’re in the BIOS, then the boot order controls. The USB drive will then be moved to the top of the list.
  • Before restarting the computer, save your settings.

Check your machine for infection with anti-malware software when it successfully starts.
