The laptop gives an error and reboots: 10 reasons and how to fix it

Your laptop suddenly shows a blue screen of death (BSOD), gives a critical error or just goes into an endless reboot? This problem is familiar to many users - from owners of budget Lenovo IdeaPad up to bonus MacBook Pro. The reasons may lie in both software failures and hardware failures. The main thing is not to panic and not to rush to take the device to a service center. In 70% of cases, the problem can be solved on your own if you correctly diagnose the source of the problem.

In this article we will look at all possible reasons spontaneous reboots with errors - from simple overheating to damage to system files. You will learn how to distinguish software glitch from hardware failurewhat tools to use for diagnostics, and what to do if the laptop gets stuck on BIOS boot screen or gives an error CRITICAL_PROCESS_DIED. We will pay special attention to cases when reboots occur only when running certain programs (for example, games or heavy applications like Adobe Premiere or AutoCAD).

1. Overheating: why the laptop turns off with an error under load

The most common reason for sudden reboots is overheating of the processor or video card. Modern laptops (especially gaming series ASUS ROG, MSI GE or Acer Predator) are automatically switched off when a critical temperature is reached (usually 95–105°C) to prevent damage to the chips. If your laptop crashes while gaming, rendering videos, or even while browsing YouTube in high resolution - check the temperature first.

How to diagnose overheating:

• 🔥 Use monitoring programs: HWMonitor, Core Temp or Speccy. Run them and watch the temperatures under load.
• 💨 Listen to the cooler: if it operates at maximum speed, but the laptop still heats up, the cooling system is most likely clogged.
• 🖥️ Check in BIOS (section Hardware Monitor): if the processor temperature is higher during idle 60°C, this is an alarming signal.

What to do:

• 🧹 Clean your laptop from dust. In 90% of cases of overheating, a dust-clogged ventilation grille or radiator is to blame. Use a can of compressed air or contact service.
• 🔄 Replace thermal paste. If the laptop is more than 2-3 years old, the thermal paste may have dried out. For Intel Core i7/i9 And AMD Ryzen 7/9 this is critical.
• 🛠️ Check the cooler. If the fan does not spin up or makes strange noises, it needs to be replaced.

⚠️ Attention: If the laptop overheats even in standby mode (for example, while simply surfing the Internet), this may indicate north bridge fault or video card damage. In this case, professional diagnosis is required.

2. Power problems: power supply, battery, connectors

If laptop gives an error and reboots when connected to the network or when running on battery power, the problem may lie in the power system. Most often the culprits are:

• 🔌 Faulty power supply (especially relevant for Dell XPS And HP Pavilion, where power supplies often fail).
• 🔋 Worn out battery (if the laptop turns off when the charger is disconnected, even if it shows 100% charge).
• 🔌 Poor contact in power connector (a common problem with Lenovo ThinkPad And Acer Aspire).

How to check:

1. Connect another power supply (if possible). If the reboots stop, the problem is in the power supply.
2. Start the laptop without a battery (on mains power only). If it works stably, the battery is faulty.
3. Rock the power plug in the connector. If the laptop turns off, soldering or replacing the connector is required.

Symptom	Probable Cause	Solution
Laptop turns off at the slightest movement of the power cord	Broken wire or poor contact in the connector	Replace the cable or resolder the connector
Works only from the mains, the battery does not charge	Battery wear or charge controller malfunction	Replace the battery or take it to service
Reboots under high load (games, rendering)	The power supply does not provide the required power	Replace the power supply with a more powerful one (for example, 90W instead of 65W)

⚠️ Attention: If laptop HP Omen or Alienware with dual core processor (Intel Core i9-12900H, AMD Ryzen 9 6900HX) suddenly turns off under load, this may be due to insufficient power of the standard power supply. Check if your PSU meets the recommended specifications for the model.

3. Failures in the operating system: from viruses to damaged files

If the laptop reboots with errors like IRQL_NOT_LESS_OR_EQUAL, SYSTEM_THREAD_EXCEPTION_NOT_HANDLED or KMODE_EXCEPTION_NOT_HANDLED, the operating system is to blame. Main reasons:

• 🦠 Viruses or malware (especially true if you download pirated software).
• 🔄 Damaged system files after an incorrect shutdown or update of Windows.
• 🔧 Driver conflict (often occurs after updating the video driver NVIDIA or AMD).

How to fix:

Check for viruses (use Kaspersky Virus Removal Tool or Malwarebytes)|

Launch sfc /scannow And DISM /Online /Cleanup-Image /RestoreHealth in command line (as administrator)|

Roll back the video card driver to the previous version (via Device Manager)|

Check error log in Event View → Windows Logs → System-->

If the laptop gives an error CRITICAL_PROCESS_DIED, this indicates critical damage to system processes. In this case it will help:

1. Loading in safe mode (click F8 or Shift + Reboot when turned on).
2. Restoring the system through a rollback point (if there is one).
3. Reinstalling Windows while saving data (if other methods do not help).

4. Malfunctions of random access memory (RAM)

If laptop reboots randomly (without reference to load or temperature), the RAM may be to blame. This is especially true if:

• Have you recently added a new RAM module.
• Laptop beeps when turned on (For example, HP gives 3 long signals - this is a memory error code).
• Errors appear when working with “heavy” programs (Photoshop, Blender, VMware).

How to check RAM:

1. Run the built-in utility mdsched.exe (type "Memory Checker" in Windows search).
2. Use MemTest86 (boot test, works outside of Windows).
3. If you have several strips, test them one at a time (take out one at a time and check stability).

Typical RAM related errors:

• MEMORY_MANAGEMENT - memory damage.
• PAGE_FAULT_IN_NONPAGED_AREA — memory access error.
• KERNEL_DATA_INPAGE_ERROR — failure to read data from RAM.

⚠️ Attention: If the memory test shows errors and replacing the strips does not help, the problem may be RAM slot on the motherboard. In this case, service repairs are required (re-soldering or replacement of the south bridge).

5. Problems with your hard drive or SSD

If laptop Stuck on loading screen or gives an error INACCESSIBLE_BOOT_DEVICE, this may indicate a drive failure. Particularly vulnerable:

• 💾 Old HDD (For example, Seagate Barracuda or WD Blue after 3–5 years of operation).
• 🔥 SSD with exhausted recording resources (especially budget models Kingston A400 or Silicon Power).

How to diagnose:

• 📊 Check it out SMART status disk using CrystalDiskInfo. If the status is "Pre-refusal" (Caution) or "Bad" (Bad) — the drive needs to be replaced.
• 🔍 Run a surface test in Victoria HDD or HD Tune. If there is bad sectors, the disk is faulty.
• 🔄 Try reinstalling Windows on another drive (if possible). If the errors disappear, the problem is in the drive.

Typical disk related errors:

• NTFS_FILE_SYSTEM - file system damage.
• KERNEL_STACK_INPAGE_ERROR — failure to read data from the disk.
• UNMOUNTABLE_BOOT_VOLUME - Windows cannot boot from the disk.

What to do if the SSD is under warranty?

If your Samsung 970 EVO, Crucial MX500 or another branded SSD under warranty, contact the service center with test results (CrystalDiskInfo or Samsung Magician). Manufacturers usually replace drives when there are critical SMART errors (for example, Reallocated Sectors Count or Uncorrectable Errors).

6. Driver and hardware conflicts

If the laptop restarts only when connecting certain devices (for example, external GPU, printer or USB-hub), the problem lies in a driver conflict. Most often this happens with:

• 🎮 External video cards (eGPU from Razer or ASUS).
• 🖨️ Old printers or scanners (especially with drivers for Windows 7 on Windows 11).
• 🔊 Sound cards (Creative Sound Blaster, Focusrite).

How to fix:

1. Update the device driver via Device Manager.
2. Remove the conflicting device in Device Manager and restart your laptop (Windows will install the driver automatically).
3. If there is a problem with eGPU, check compatibility with your laptop model (not all Thunderbolt 3 ports support external video cards).

Typical errors in driver conflicts:

• DRIVER_IRQL_NOT_LESS_OR_EQUAL — the driver is trying to access a prohibited memory area.
• DRIVER_POWER_STATE_FAILURE — failure when the device goes into sleep mode.

7. Viruses and malware

Some viruses (for example, miners or rootkits) can cause critical system crashes leading to reboots. Particularly dangerous:

• 🦠 Miners (use CPU/GPU resources at 100%, causing overheating).
• 🕵️ Rootkits (injected into the system kernel, causing errors SYSTEM_SERVICE_EXCEPTION).
• 📂 Encryptors (may damage system files).

How to check and clean:

1. Boot into safe mode with network support.
2. Run a scan Kaspersky Rescue Disk or Dr.Web LiveDisk (boot antiviruses).
3. Check startup (Ctrl + Shift + Esc → Startup) for suspicious processes.

If the laptop restarts when opening the browser or running certain programs, it is almost always a virus. Please note:

• Unexpected processes in Task Manager (For example, svchost.exe with high load).
• New browser extensions that you did not install.
• Change your home page or search engine.

8. Hardware faults: motherboard, video card, processor

If all software methods have been tried, but the laptop still gives an error and reboots, the problem may be hardware. The most common faults:

• 🔧 Motherboard damage (for example, swollen capacitors or burnt tracks).
• 🎮 Discrete graphics card malfunction (relevant for laptops with NVIDIA GTX/RTX or AMD Radeon).
• 🖥️ Processor problems (rare, but possible with physical damage).

How to diagnose:

• 🔍 Inspect the motherboard for swollen capacitors or traces of burning.
• 🔄 Try starting your laptop with disabled discrete video card (if it is removable).
• 📊 Check it out BIOS logs (in some laptops, for example Lenovo ThinkPad, there is a hardware error log).

Typical symptoms of hardware problems:

• Laptop doesn't turn on at all or turns off a few seconds after starting.
• Appear artifacts on the screen (banding, flickering, distortion).
• Heard squeak or crackle from the speakers (may indicate problems with the video card).

⚠️ Attention: If laptop MSI or Gigabyte with video card NVIDIA RTX 30xx gives an error VIDEO_SCHEDULER_INTERNAL_ERROR, this may be due to graphics chip degradation. In this case, you need to replace the video card or resolder the GPU.

FAQ: Frequently asked questions about laptop reboots

The laptop reboots when the game starts. What is the reason?

Most likely the problem is overheating of the video card or malnutrition. Check GPU temperature using MSI Afterburner and make sure that the power supply provides enough power (for example, for RTX 4070 may require 180W PSU). Also update your video card drivers and scan your laptop for viruses.

After updating Windows, the laptop began to reboot. What to do?

Revert to a previous version of Windows via Settings → Update & Security → Recovery. If this doesn't help, run the commands sfc /scannow And DISM /Online /Cleanup-Image /RestoreHealth on the command line (as administrator). Also check that the drivers are compatible with the new version of Windows.

The laptop gives an error CRITICAL_PROCESS_DIED and goes into reboot. How to fix it?

This error indicates critical damage to a system process. Try:

1. Load into safe mode and perform a system restore.
2. Check the disk for errors with the command chkdsk /f /r.
3. Reinstall Windows while saving the data (if other methods do not help).
