The most common reasons for computer failure in a corporate environment

Computer downtime in a company costs on average 501 hours per year, which translates into millions of złoty lost due to decreased efficiency. Problems with company computers can take many forms – from an annoying blue screen to a complete lack of signal on the monitor. Let's learn about the most common computer failures in the business environment and their solutions.

Computer crash, blue screen - causes and symptoms

The Blue Screen of Death (BSOD) occurs when Windows encounters a serious problem that forces the system to stop immediately to prevent data loss. The screen displays an error message and a STOP code (e.g. PAGE_FAULT_IN_NONPAGED_AREA) that helps identify the cause of the problem.

The most common causes of a blue screen in a corporate environment are:

  • Corrupt or incompatible device drivers
  • Hardware problems (especially RAM)
  • Computer components overheating
  • Malware or viruses
  • Sudden voltage spikes damaging sensitive components

The blue screen is rarely caused by a user process – it’s usually a driver, hardware, or operating system issue. To quickly identify the cause, it’s worth paying attention to the error code and the name of the module that failed.

Black screen problems – what could be the cause?

The black screen is often more frustrating than the infamous BSOD because it does not provide any error codes. Device overheating is the most common cause of a computer randomly shutting down and displaying a black screen. In this case, check that the computer is free of dust and that the device is placed on a flat surface in a cool, well-ventilated place.

Other common causes include:

  • Problems with the graphics card or its drivers
  • Incorrect display projection settings (Win+P)
  • Incorrect hardware connections
  • Malware
  • BIOS/UEFI configuration issues

If you see a black screen after logging in, try refreshing the screen using the Windows + Ctrl + Shift + B key combination, which will force the graphics driver to restart.

No signal on monitor - problem diagnosis

The problem of no signal on the monitor may be due to a broken connection between the computer and the display device. If the monitor displays a "no signal" message, first check if the video cable is properly connected to both devices.

When diagnosing this problem, it is worth:

  1. Disconnect all accessories from the computer (docking stations, adapters)
  2. Replace the cable connecting the computer to the monitor with a working one
  3. Test the monitor with another device
  4. Try connecting the monitor to a different video port (HDMI, VGA, DVI, DisplayPort)
  5. Check projection settings (Windows + P)

If all connections are correct, the problem may be with the graphics card drivers or the graphics card itself.

Hardware failures vs. software problems

Distinguishing between hardware and software failures is key to effectively troubleshooting the problem. Statistics show that nearly 80% of technical problems are due to configuration errors or physical defects in devices.

Hardware failures are often characterized by:

  • Unusual sounds coming from the computer
  • Device overheating
  • Physical signs of damage
  • System randomly restarting or shutting down
  • Slower operation of the device over time

Hard drives are particularly susceptible to failure because they are constantly spinning and generating heat. If a hard drive fails, it could mean the loss of all your data.

On the other hand Program problems usually manifest themselves as:

  • Frequent crashes or unexpected shutdowns of programs
  • Slow performance when executing commands
  • Error messages appearing regularly
  • Inability to save or access important files

It is worth remembering that hardware failures become more frequent as hardware ages. Every company should have a hardware replacement policy in place to eliminate potential unforeseen expenses and unwanted computer failures.

How to Solve Blue Screen of Death (BSOD) Problem

The Blue Screen of Death (BSOD) is a problem that can paralyze your work in a company for hours. However, with the right knowledge, most BSOD cases can be solved on your own. Let's look at effective methods to fix this common problem.

Reading BSOD error codes

The Blue Screen of Death always displays an error code that is key to identifying the cause of the problem. On newer versions of Windows (10 and 11), it also displays a QR code that you can scan with your phone to get more information about the problem.

Most common BSOD error codes and their meanings:

  • 0x0000000A (IRQL_NOT_LESS_OR_EQUAL) - the process is trying to access more memory than is allowed
  • 0x00000050 (PAGE_FAULT_IN_NONPAGED_AREA) - a system process is trying to access a non-existent memory address
  • 0x0000003B (SYSTEM_SERVICE_EXCEPTION) – identifies the driver or system process that caused the error
  • 0x000000D1 (DRIVER_IRQL_NOT_LESS_OR_EQUAL) - driver problem
  • 0x1000007E (SYSTEM_THREAD_EXCEPTION_NOT_HANDLED) - probably outdated or faulty driver

Be sure to write down the error code before restarting your computer. The vast majority of BSOD errors (about 75%) is caused by faulty drivers, so updating them should be the first step.

Updating drivers as the first solution

Drivers are software that allow Windows to communicate with your hardware. Outdated or corrupt drivers are the most common cause of the blue screen of death, especially after installing new hardware or upgrading your system.

To update drivers:

  1. Press the keys Windows + X and select "Device Manager"
  2. Check if any device is marked yellow exclamation mark (!)
  3. Right-click on such a device and select "Update Driver"
  4. Select the automatic driver search option

If you are still having problems after installing the driver, it is worth trying to roll back the driver update. To do this, right-click on the device in Device Manager, select "Properties", go to the "Driver" tab and click "Roll Back to Previous Driver".

Special attention should be paid to drivers for graphics cards, network controllers and storage devices, which are most likely to cause BSOD problems.

Checking RAM and hard drive

Hardware failures, especially RAM and hard drive issues, often lead to computer failures. Fortunately, Windows has built-in diagnostic tools to check these components.

Checking RAM:
  1. Press the key Windows and type "memory diagnostics"
  2. Select "Windows Memory Diagnostic Tool"
  3. Click "Restart now and check for problems"

The test will take about 10 minutes and will automatically detect problems with your RAM. If the test shows errors, you will probably need to replace your memory.

Checking the hard drive:
  1. Open a command prompt as administrator (Windows + X, then select "Command Prompt (Admin)")
  2. Enter command chkdsk /f /r and confirm with Enter
  3. Confirm that you want to run the scan the next time you restart your computer

Recommendation chkdsk /f /r will scan the disk for errors and bad sectors and then attempt to repair them.

If BSOD problems occur after installing new software, it is also worth running the command sfc /scannow in the command line to repair corrupted system files.

In case of recurring blue screen problems in the company, which paralyze the work of the team, it is worth contacting professional help. Company ProsteIT.pl specializes in solving technical problems for companies, providing quick diagnostics and effective repairs that minimize downtime.

Troubleshooting a black computer screen

A computer crash with a black screen is a common problem that can be incredibly frustrating for employees. It effectively paralyzes work because it does not provide any diagnostic clues, unlike a blue screen with error codes.

Checking connections and power supply

Before we move on to more advanced solutions, it is worth checking the simplest causes of failure related to hardware connections. Often, the black screen problem is caused by a broken connection between the computer and the monitor.

First, check that the video cable (VGA, DVI, HDMI, or DisplayPort) is properly connected to both devices. Sometimes, the cable has become loose or is not properly seated in the port. If the problem persists, try:

  1. Disconnect and reconnect the video cable on both ends
  2. Test another video cable (e.g. the one used by the TV or another monitor)
  3. Check if the monitor is set to the correct signal source (Input/Source button)
  4. Connect the monitor to another port on your computer (if available)

For laptops, try disconnecting all external devices and leaving only the power supply connected. Also, make sure the power supply is connected properly and working. Overheating of the device is the most common cause of random shutdowns and black screens.

Graphics card diagnostics

The graphics card or its drivers are often the cause of black screen problems. If the screen is black but the computer seems to be working (you can hear Windows startup sounds), you may want to:

  1. Use key combination Windows + Ctrl + Shift + Bto force restart the graphics driver
  2. Check that the Caps Lock LED on your keyboard is not lit, which will confirm that the computer is responding.

If you have a desktop computer with a graphics card that is additionally powered, check that the 6Pin or 8Pin power cable is properly connected. If your computer has an integrated graphics processor, you can:

  1. Turn off the computer
  2. Disconnect the graphics card
  3. Connect the monitor to the appropriate port on the motherboard
  4. Start the system on integrated graphics

If your computer works fine on integrated graphics, the problem lies with the graphics card or its drivers. However, before installing new ones, check the temperature inside the case - excessive temperature can cause components to malfunction and no display signal.

BIOS/UEFI Reset

BIOS/UEFI configuration issues can also cause a black screen. To reset the BIOS/UEFI:

  1. Turn off your computer completely (hold the power button for a few seconds)
  2. Restart and immediately press F2 or Delete (depending on your motherboard model)
  3. If you can enter BIOS/UEFI, find the option "Load defaults" or "Restore defaults"

In case you are unable to enter BIOS/UEFI, you will need to clear the CMOS:

  1. Turn off your computer and unplug the power cable
  2. Open the computer case
  3. Locate the CMOS battery (round battery) on the motherboard
  4. Remove the battery for a few minutes, then reinsert it

Resetting the BIOS/UEFI restores default settings, which often resolves black screen issues.

What to do if the computer does not detect the monitor

The problem of the computer not detecting the monitor is one of the most common failures that can completely stop work. Unlike a blue or black screen, here we do not see any image - the monitor informs about the lack of signal or goes into energy saving mode.

Verification of cable connections and ports

First of all, check that the monitor is connected to a power source and turned on. Then, check that the signal cable (HDMI, DisplayPort, VGA, or DVI) is properly connected to both the monitor and the computer.

Worth a try:

  1. Disconnect all accessories from your computer (docking stations, adapters) that may cause conflicts
  2. Check if the cable connecting the computer to the monitor is properly connected
  3. Replace the cable with a new one - the old one may have been damaged
  4. Connect the monitor to a different video port if your computer has more than one.

If your computer has a graphics card, make sure the monitor is connected to it and not to the integrated graphics on the motherboard.

Testing the monitor with another device

To determine if the problem is with your monitor or computer:

Connect the monitor to another computer or laptop. If it works properly, the problem is most likely with the original device.

Try connecting another working monitor to your computer. If the second monitor works, the fault is with the first monitor.

Check the settings built into the monitor – use the buttons on the housing to select the appropriate input source (HDMI, DisplayPort, etc.).

Troubleshooting display driver issues

If the connections are correct and the problem persists, the cause may be in the software:

If Windows detects the monitor but does not display an image, press the combination Windows + Pto make sure the option is selected Expand.

Sometimes resetting the graphics driver helps - press Windows + Ctrl + Shift + B.

To update, roll back, or reinstall your graphics driver:

  1. Open Device Manager
  2. Expand the "Graphics Cards" section
  3. Right-click on your graphics card and select "Update Driver" or "Uninstall Device"

Prevention of computer failures in the company

Preventing computer failures is definitely cheaper and less stressful than fixing their effects. Studies show that systematic preventive measures can reduce the risk of serious computer failures by up to 80%. Let's look at the most effective methods for preventing technical problems in your company.

Regular system and software updates

Outdated software is a major security risk for your business. Cybercriminals exploit vulnerabilities to steal business, employee, or customer data. Software manufacturers create updates (called patches) for these vulnerabilities. However, if you don’t install these updates, they can’t protect you!

First and foremost, enable automatic updates for all operating systems and third-party software. Also, create a hardware maintenance schedule and replace aging components before they fail.

Obsolete hardware and software that is no longer supported (end of life) should be replaced. Therefore, regularly inventory authorized hardware and software across the organization.

Backing up corporate data

The statistics are alarming: almost 40% of companies that experienced data loss lost 20% of their revenue as a result of the incident. To prevent this, apply the 3-2-1 rule: have 3 copies of your data, stored on 2 different media, 1 of which off-site.

Cloud backups have low upfront costs and are accessible from any device with an internet connection. Local backups, on the other hand, offer speed and security control.

Remember to test your backups regularly – restore them in a test environment and check that all data is available as expected.

Training employees in basic diagnostics

Explain to employees, especially those working remotely, why software updates are important and why they shouldn’t be delayed. Encourage them to enable automatic updates on their own devices and software.

Training should include methods for troubleshooting both hardware and software problems. Employees should be able to use a systematic approach to diagnosing technical problems.
