Common Computer Problems

Power Related Issues

Symptoms: No image on Monitor and no noise is heard from the main tower.

  1. Place yourself behind the computer and find the thickest black cable. This is the cable that brings electricity to your computer. Ensure that it’s plugged in all the way inside the socket on the computer.
  2. Follow the power cable away from the Tower and towards the electrical outlet. Ensure that th power cable is plugged in correctly into the electrical outlet.
  3. Behind the Computer, find the rocker switch and Put it in the “OFF” position.
  4. Go to the front of the Computer and press the Power Button.
  5. Put the rocker switch in the back of the computer back to the “ON” position.
  6. Go to the front of the Computer and press again the Power Button.

If after performing the troubleshooting steps above, the computer is still not powering on, the power supply might need to be replaced. Contact us to speak to one of our computer technicians, confirm the issue and to obtain an estimate. If you like what you hear and would like to take advantage of our Computer Repair Service to replace your Computer’s Power Supply, we can often provide same day service.

If your power supply failed, you might want to consider adding a UPS, to avoid incurring into the same issue again. In addition to the benefit of allowing your computer to continue to run for a short period of time, after the primary power source is lost, a UPS provides protection from power surges as well. Power surges are the primary cause of Power Supply failures and what most likely happened in your case.

Symptoms: No image on Monitor but you do hear noise coming from the main tower.

  1. Ensure that your Monitor is powered on. The power status is indicated by a LED light on the front face of the Monitor, usually near the power button.
  2. If your Monitor is not powered on and it cannot be powered on by pressing its power button, ensure that the Monitor is correctly plugged into the electrical outlet.
  3. Place yourself behind the Monitor and ensure that the power cable is correctly plugged in to the power socket and that it cannot be pushed further in.
  4. If the Monitor is still not powering on, try and use a different electrical outlet.

If after following the troubleshooting steps above, the Monitor still cannot be powered on, it might need repairs or replacing. Contact us to speak to one of our computer technicians, confirm the issue and obtain an estimate.

Failure of the LCD backlight is a fairly common problem beginning to crop up in LCD technology. If the backlight fails, the monitor will go dark and it will become unusable. If your LCD screen goes completely black, it may mean that the Monitor’s Power Supply has failed. If it uses an external Power Supply, you could try and replace it with a different one taken from a similar model.

If the Monitor does power on, first ensure that your computer is also powered on. If your computer is not running, press the power button on the tower to turn it on, then look at the Monitor to notice if you see any image. If you do not see any image on the screen:

  1. While behind the Monitor, look for a blue OR white connector. This is the cable that brings the signal from the computer to the monitor.
  2. Ensure that the connector is correctly plugged in and that it cannot be pushed further in.
  3. Follow this cable until it reaches the back of the computer.
  4. Ensure that it’s plugged in correctly and that it cannot be pushed further in.
  5. Look at the Monitor and notice if you see any image.

If you still cannot see any image on the Monitor, your Video Card might need to be replaced. The Video Card is a component that sits inside the computer case and is responsible for sending video signals to your monitor. Contact us to speak to one of our computer technicians, confirm the issue and obtain an estimate. If you like what you hear and would like to take advantage of our Computer Repair Service to replace your Video Card, we can often provide same day service.

Cryptic Error Messages

If the screen looks like the image below, this is called the Blue Screen of Death, or BSOD for short. A blue screen occurs when Windows encounters an error from which it cannot recover, called “STOP Error.” This critical failure causes Windows to crash and stop working. The only thing Windows can do is stop the computer and restart it. BSOD are mostly caused by hardware related issues but they can also be software related. If your computer has been working fine until now, it is possible that your issue is software related.

BSOD Caused by Software

  • Virus or Malware have infection: Try and boot in Safe Mode and scan with Malwarebytes.
  • Incompatible Software: You have just installed a new piece of software and it’s interfering with the normal operation. Try uninstalling that software to see if the issue goes away.
  • Low space on your Hard Disk Drive: Data corruption and other serious issues can occur if there’s not enough free space on the primary partition used for the Windows operating system.
  • Outdated or incompatible drivers: incorrectly installed or buggy driver can lead to crashes. Download the latest drivers for your computer’s hardware from your computer manufacturer’s website and install them.

BSOD Caused by Hardware

  • Failing RAM Memory: By far the most common reason is failing RAM Memory. Not to be confused with the Hard Disk Drive, RAM Memory can be tested with software tools such as MemTest.

  • Failing Hard Disk: The Hard Disk is where all your data is stored. Failing Hard Disks can experience data corruption. When important Windows files get corrupted, BSOD can occur. Hard Disks can be tested with software tools provided by their manufacturers. Backup your data as soon as possible and before running any tests.
  • External Devices: Sometimes a defective external device connected to the computer can cause BSOD. Try and disconnecting all external devices such as Printers, Flash Drives, Smartphones, USB Hubs to see if the issue goes away.
  • Other Components: Often a defective or incorrectly installed Add-On Card can cause BSOD. Add-On Cards are installed inside the computer to give it additional functionality. To check them you have to open your Desktop. We do not recommend doing this yourself as you might cause additional damage to other components. However if you want to do it anyway, before touching any component inside the computer, unplug it from the electrical outlet first. With the cord unplugged, press the Power Button to discharge any capacitors that may still hold a charge. Finally, before touching any components inside the computer, make sure you touch the outside of the case to discharge any static electricity you may be holding in your body. Static electricity can damage the components inside your computer. Try and remove all Add-On cards that are not needed for the normal operation of your Desktop Computer, close the case, power on your Desktop and see if you notice any difference.
