❖There are few more terrifying things than coming face to

face with the blue screen of death (BSOD). Maybe you’re
rebooting your computer or you’ve just updated your PC
and now your device is unusable. You’re at risk of losing
valuable files, especially if they haven’t been backed up.

❖Don’t panic! There are some common fixes for this

unsettling screen warning so let’s dive into it so you can
get back to your regular computing.

What is the Blue Screen of Death in Windows 10 and How to Fix it?

Blue Screen Issue

❑ Primary Diagnosis

❖The blue screen of death is also called a stop message or

stop error. Colloquially, it’s known as the blue screen of
doom, bug-check screen, system crash, or simply blue
screen error. It signifies a system crash stemming from
internal issues that we will explore in-depth below.

What is the blue screen of death?

Blue Screen Issue

❑ Primary Diagnosis

❖ Typically, BSODs result from driver software or issues with hardware. Apps that

crash sometimes cause blue screens of death if they’re broken or flawed.

❖ Windows creates what’s known as a minidump file when a BSOD happens. This file

contains information about the crash and saves it to the disk. However, in most cases,
Windows automatically restarts when a blue screen appears.

If you want more time to see what the minidump file is or to see if it’s a blue screen
❖ happening at all, you can disable automatic restarts on BSODs from the Windows

Control Panel.

When your PC restarts after a blue screen, it goes through an automatic troubleshooting
and repair process on its own. However, if Windows can’t repair the issue, you can start to
troubleshoot your own.

If you can isolate the actual Stop Error number or code, you can search the web for the
cause of the exact error. Or refer to this helpful list of common BOSD error codes and their
meanings.

What causes the blue screen of death?

Blue Screen Issue

❑ Primary Diagnosis

❖ First, figure out if you took any actions before the BSOD occurred.

Did you install a new

program, update a driver, or initiate other software changes?

If you did any of these

things, that may be what caused the BSOD.

❖ Undo your last action and test for the STOP Error message. Depending on the change that

occurred, these fixes may work:

•Start your PC using the Last Known Good Configuration

•Utilize System Restore

•Go back to the previous device driver before your latest update
If these do not fix the problem here are some things to check:
1. Check for driver space because if there’s not enough, it may cause a BSOD to rear its ugly blue head
Pro tip: We recommend Windows users aim to keep around 15% of their drive space free for optimal
PC operation.

2. Check the device’s temperature

A device that’s overheating can lead to a system crash and a blue screen of death. Make sure that your
PC has adequate cooling systems so you don’t risk this problem.
3. Scan for malware and viruses

4. Look for any patches

Microsoft provides patches and service packs for operating systems that may include fixes
for your BSOD.

5. Update drivers for your hardware

Updating your drivers can fix your STOP error in some instances.

6. Check the System and Application logs in Event View to spot possible errors

7. Change your hardware settings to default in Device Manager.

If you have customized settings, that could be the root issue for your BSOD.

8. Ensure you have default BIOS settings.

9. Have you recently tried to install new memory or expansion cards?

How do I fix the blue screen of death on Windows 10?

Blue Screen Issue

❑ Primary Diagnosis

Double-check that the components were installed and seated correctly.

10. Use diagnostic tests to find out if you have malfunctioning hardware somewhere in
your computer since that’s often the culprit behind a blue screen

11. Update your BIOS
If your BIOS is out-of-date, it could lead to system crashes.

12. Start your PC with essential hardware

This is a good way to test what hardware is working and what isn’t.

13. Reinstall Windows
This wipes the slate clean and starts the operating system fresh. However, it should only be
an action you use as a last resort because it will restore your entire computer to factory
settings, erasing any files.

Troubleshooting Black Screen Displays
with No Error Messages During Startup or Boot

❖ There are many reasons that a computer does not startup or

boot into the Windows operating system. If your computer will
not start or boot, you will see or hear symptoms to indicate the
general area of the problem

❖ Startup Symptom: LEDs glow, but computer fails to startup or

boot, and displays a black screen

❖ Use this document if the LEDs glow to indicate that power is

available and the sound of a fan or spinning hard drive can be
heard, but no colors, images, or text are displayed on the LCD
display.

❖ Do not use this document if there are no sounds from

the computer when the power is turned on. You should
check for a different problem; such as a loose RAM
memory chip or disconnected hard drive.

❖ The cause of this problem may be the failure of a

hardware component, or an error in the instruction
being sent from the BIOS to a hardware component.

Before you begin troubleshooting your computer

Before you begin troubleshooting your computer, perform the following steps:

Step one: Perform a hard reset

If your computer suddenly fails to boot properly, you should perform a hard reset.

1.Disconnect all peripheral devices and remove all USB devices and media cards

. You

want to test the computer not the accessories!

1.Disconnect the AC power adapter, remove the battery, and then press and hold the
power button for at least 15 seconds.

2.Reconnect the AC power adapter (but do not connect the battery), Press the Power
button, Look for glowing LEDs near caps lock and num lock keys, and Listen
for sounds of a disk drive and fan turning.

❖ If the display remains blank (black screen or white

screen) after doing a hard reset, temporarily connect an
external monitor to test the notebook's display.

❖ If an image displays on the external monitor, continue to

perform the tests, install drivers, and make adjustments
as described in the next section.

❑ Step two: Connect an external monitor to test the display

1. If there are no sounds from the computer when the power is turned on, check for a
different problem; such as a loose RAM memory chip or disconnected hard drive.

2. If you are having trouble viewing the external monitor, click f4 (or the key with this
symbol ) to switch the screen image among display devices connected to the system. For
example, if a monitor is connected to the computer, pressing this key alternates the
screen image from computer display to monitor display to simultaneous display on both
the computer and the monitor.

3. If an image displays on the external monitor, there may be a graphics driver conflict
with the notebook’s LCD display. With the external monitor connected, download and
install the latest drivers for your specific computer and graphic chip set.

4. If you do not have an external monitor, it may be possible to see an image by switching
the LCD display to a low resolution mode. To change the resolution, turn on the
computer, and press the f8 key. If the graphic display is working at the BIOS level, a text
screen displays and you can select the Enable low-resolution video option. If the graphics
display is not working at the BIOS level, contact an authorized repair center.

❑ As a final action, if there is an image on the external monitor and you have

installed the latest BIOS, updated CPU chips set, and updated graphics
drivers but the notebook display remains black, the LCD may be defective. It
may be necessary to contact HP for technical assistance or send the
notebook for service to replace the display.

❑ Step three: Disconnect all peripherals and repeat the hard reset

❖ Even when instructed to disconnect all peripheral devices from the notebook before

doing a hard reset, some devices are often overlooked.

Double-check that all devices are disconnected including: external keyboard and mouse
(wired or wireless), USB connected external drives and devices, thumb drives and flash
drives, network storage devices, PC card, SD memory cards, express card, eSata
connections, firewire or similar devices, printer, scanner, camera, port replicator, or
docking station, any CD/DVD from the optical disc drive, and any media from the multi-
card reader.

❑ Test for memory module problems

❖ When you try to turn on a computer, one of the first hardware tests performed is the

memory check. If the start up test cannot access the memory chips, the testing stops
and no additional actions can be taken. In other words, when you press the power
button the LEDs may glow for a moment and a fan may start to spin, but then all
action stops.

1. Check for loose memory modules

2. Test two memory modules

3. Test two memory slots

4. Test for memory problems using HP PC Hardware Diagnostics

❖ The Memory Tests include a Fast Test, Quick Test, and an Extensive Test. If you think there is a problem with the

memory, first try the Fast Test (3 to 5 minutes). If the Fast Test does not find a problem, run the Quick Test (about 10
minutes). If the Quick Test does not find a problem, run the Extensive Test (about 45 minutes) which also has a Loop
Until Error option.

Hardware Failures.

Follow these steps to run the Fast Test:

1.Hold the power button for at least five seconds to turn off the computer.

2.Turn on the computer and immediately press Esc repeatedly, about once
every second. When the menu appears, press the F2 key.

How Do I Fix a Laptop that Won’t Turn On?

❖ You press the power button on your laptop... and nothing

happens.

There are few more frustrating technological hiccups than when
your laptop won’t turn on. However, you don’t have to resign
yourself to the idea that your laptop has met an untimely death.
We’ll show you some ways to assess what’s wrong and fix it.

❖ If your laptop won’t power up, a faulty power supply, failed

hardware, or a malfunctioning screen could be to blame [1]. In
many cases, you may be able to resolve the problem yourself by
ordering replacement parts or adjusting your laptop’s
configuration.

But if your laptop is older and the problem is an expensive hardware
issue, it may make be the best time to buy a new laptop.

How Do I Fix a Laptop that Won’t Turn On?

Check the power supply and battery

If your HP laptop won’t turn on even when plugged in, start by checking the
power supply. There are quite a few issues you could have with the power
supply.

For example, the problem could be as simple as having the wrong charging
cord which means you aren’t getting the proper voltage, or it could be that
the power supply has failed [2].

1. To test if the power supply is the issue, completely remove your laptop
battery.

2. Then, plug your laptop into a functioning outlet.

3. First, confirm the outlet is functioning properly by plugging another
device into it - if it works, the issue isn’t the outlet.

2. Remove all devices from your laptop

If you have left a memory card, DVD, or USB drive in your notebook, this could
be a reason why your laptop doesn’t power on.
It might be getting “stuck” because the BIOS may be trying to boot from a
removable storage device. Remove all USB drives and other devices and try to
boot up your computer.

3. Use a rescue disc

A rescue disc allows you to boot your computer and fix any issues you may be
having with a Windows operating system [5]. If a virus is the culprit behind your
computer problems, the rescue disc will find it via scanning tools so you can
remove the offending malware.

5. Boot in safe mode

If your HP laptop won’t turn on you might still be able to get your laptop working in safe
mode [6]. Safe mode allows you to uninstall new programs or drivers that could be
affecting your laptop. It also allows you to create a new user account if your original
account has been corrupted.

6. Check hardware

The last step when diagnosing power issues is to check your hardware. If you’ve recently
installed hardware like a new RAM kit, that could be the cause of your boot issues.
Remove and reinstall your new hardware and try to boot again.
Unfortunately, sometimes the hardware in your laptop such as your hard drive simply fails
and there is no easy fix. If you hear a clicking noise or the drive spinning but then
powering down, this is a telltale sign your hard drive has failed [7]. In most cases, this
means you’ll need to simply replace your hard drive.
In instances like this, it is smart to have an external hard drive so you can back up any files
you may need.
