Why does my PC blue screen when I play games?

Gaming BSODs are most commonly caused by GPU driver failures (look for VIDEO_TDR_FAILURE or SYSTEM_SERVICE_EXCEPTION with nvlddmkm.sys or amdkmdag.sys listed), overheating graphics cards or CPUs, faulty or overclocked RAM causing MEMORY_MANAGEMENT errors, or power supply units that cannot deliver stable power under full gaming load. Start by using DDU to clean-install your GPU drivers, monitor temperatures with HWMonitor during gaming, and run MemTest86 overnight to rule out RAM issues.

My PC blue screened and now it won't boot — how do I fix it?

Force power off and on 3 times to trigger Windows Recovery Environment (WinRE). From there, try Startup Repair first (Troubleshoot > Advanced Options > Startup Repair). If that fails, open a Command Prompt and run: 'bootrec /fixmbr', 'bootrec /fixboot', and 'bootrec /rebuildbcd'. Also run 'chkdsk C: /f /r' from WinRE to repair disk errors. If none of these work, use System Restore from WinRE or boot from a Windows USB and perform a repair install.

What does KERNEL_SECURITY_CHECK_FAILURE mean on my PC?

This BSOD (stop code 0x00000139) means a kernel-level data structure was corrupted, which Windows detected through its security checks. Common culprits are outdated drivers (especially GPU drivers after a Windows version upgrade), overclocked or unstable RAM, and occasionally malware. Fix: Boot into Safe Mode, run 'sfc /scannow' and 'DISM /Online /Cleanup-Image /RestoreHealth', use DDU to reinstall GPU drivers cleanly, and run Windows Memory Diagnostic. If you recently enabled XMP/EXPO in BIOS, try disabling it temporarily.

I'm getting a blue screen that says 'There was a problem resetting your PC' — what do I do?

This error occurs when Windows cannot complete the factory reset process due to corrupt system files or a damaged recovery partition. Boot from a Windows 10/11 USB installation drive, select 'Repair your computer', then use Command Prompt to run: 'bootrec /fixmbr', 'bootrec /fixboot', 'sfc /scannow', and 'DISM /Online /Cleanup-Image /RestoreHealth'. If the reset still fails, perform a clean install of Windows from the USB drive, choosing 'Custom: Install Windows only' to preserve your data on a separate partition or after backing up.

Why does my new CyberPower PC or gaming PC keep blue screening?

New PCs (including CyberPower pre-builts) blue screen for several common reasons: RAM not running at its rated XMP/EXPO speed in BIOS, GPU drivers not installed correctly (Windows uses a generic driver that's unstable under gaming load), CPU or GPU overheating due to improper thermal paste application or airflow, or a faulty RAM module. Start by entering BIOS and enabling XMP/EXPO, then download and clean-install the latest GPU drivers from NVIDIA or AMD. Use HWMonitor to check temperatures under load. If BSODs persist, reseat all RAM sticks and test with one stick at a time.

Understanding the PC Blue Screen of Death (BSOD)

A Blue Screen of Death (BSOD) — officially called a Stop Error — occurs when Windows encounters a critical system error it cannot recover from safely. The OS halts all operations to prevent data corruption and displays a blue screen with a stop code. Modern Windows 10/11 BSODs show a sad face emoji, a brief description, and a stop code such as:

KERNEL_SECURITY_CHECK_FAILURE
MEMORY_MANAGEMENT
PAGE_FAULT_IN_NONPAGED_AREA
IRQL_NOT_LESS_OR_EQUAL
SYSTEM_SERVICE_EXCEPTION
CRITICAL_PROCESS_DIED
VIDEO_TDR_FAILURE

Each code maps to a specific Windows subsystem, making them invaluable for diagnosis.

Common Scenarios and Their Causes

New PC Blue Screen / CyberPower PC Blue Screen

New builds (including pre-built systems like CyberPower PCs) frequently blue screen due to:

RAM not seated properly or running at incorrect XMP/EXPO speeds
GPU drivers not installed (system uses generic drivers)
Thermal paste not applied correctly, causing overheating
Fast Startup causing boot conflicts

PC Blue Screen When Playing Games / While Gaming

Gaming BSODs are almost always caused by:

GPU overheating or overclocking instability
Faulty or outdated GPU drivers (VIDEO_TDR_FAILURE, SYSTEM_SERVICE_EXCEPTION)
Insufficient or faulty RAM (MEMORY_MANAGEMENT)
Xbox Game Pass overlay or anti-cheat conflicts

PC Blue Screen After Startup / Won't Boot

Corrupt boot sector or MBR
Failing hard drive (bad sectors)
Windows Update corruption

"There Was a Problem Resetting Your PC" Blue Screen

Corrupt Windows installation files
USB recovery drive not recognized
Damaged system partition

Step-by-Step Troubleshooting

Step 1: Record the Stop Code

When the BSOD appears, note:

The stop code (e.g., MEMORY_MANAGEMENT)
The failed module listed under "What failed:" (e.g., ntoskrnl.exe, nvlddmkm.sys)

If the PC reboots too fast: Open Settings > System > About > Advanced System Settings > Startup and Recovery > Settings, then uncheck Automatically restart.

Step 2: Boot into Safe Mode

If Windows won't load normally:

Force shutdown 3 times to trigger Windows Recovery Environment (WinRE)
Navigate to Troubleshoot > Advanced Options > Startup Settings > Restart
Press 4 for Safe Mode or 5 for Safe Mode with Networking

Step 3: Check Event Viewer

In Safe Mode or after a reboot:

Press Win + X and select Event Viewer
Navigate to Windows Logs > System
Look for Critical or Error events timestamped at the crash time
Note the Source and Event ID for targeted fixes

Step 4: Analyze Minidump Files

Windows saves crash dumps at C:\Windows\Minidump\. Use WinDbg or the free tool WhoCrashed to analyze them:

WinDbg command: !analyze -v

This reveals the exact driver or process that caused the crash.

Step 5: Run System File Checker and DISM

Corrupt system files frequently cause BSODs. Run from an elevated Command Prompt:

sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth

Restart after completion.

Step 6: Run Windows Memory Diagnostic

For MEMORY_MANAGEMENT or random gaming BSODs:

Press Win + R, type mdsched.exe, press Enter
Choose Restart now and check for problems
For deeper testing, use MemTest86 from a bootable USB (run overnight)

Step 7: Check Disk Health

For BSODs after startup or boot failures:

chkdsk C: /f /r /x

Schedule for next restart if the drive is in use. Also check SMART data:

wmic diskdrive get status

Step 8: Update or Roll Back Drivers

For GPU drivers (most common gaming BSOD cause):

Download DDU (Display Driver Uninstaller), boot into Safe Mode, run DDU to fully remove GPU drivers
Download the latest driver from NVIDIA or AMD official site and install clean
If BSOD started after a driver update, roll back: Device Manager > Display Adapters > right-click GPU > Properties > Driver tab > Roll Back Driver

For all drivers:

pnputil /enum-drivers

Step 9: Disable Fast Startup (New PC / Boot BSODs)

Open Control Panel > Power Options > Choose what the power buttons do
Click Change settings that are currently unavailable
Uncheck Turn on fast startup

Step 10: Fix "There Was a Problem Resetting Your PC"

Boot into WinRE and use the Command Prompt:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

If that fails, boot from a Windows installation USB and choose Repair your computer.

Step 11: Check Temperatures and Hardware

Install HWMonitor or HWiNFO64 to monitor:

CPU temperature (should stay under 90°C under load)
GPU temperature (under 85°C)
RAM temperatures

For CyberPower PCs and new builds, physically reseat RAM sticks — remove them and firmly reinsert, one stick at a time to identify a faulty module.

Step 12: Xbox Game Pass / UWP App BSODs

Xbox Game Pass games have triggered SYSTEM_SERVICE_EXCEPTION and KERNEL_SECURITY_CHECK_FAILURE errors due to:

Conflicting anti-cheat drivers
WSA (Windows Subsystem for Android) conflicts
Corrupt game installation

Fix: Uninstall and reinstall the problematic game, disable Xbox Game Bar (Win + G > Settings > uncheck Enable Xbox Game Bar), or update the Xbox app.

Recovery When Windows Won't Boot

If the PC blue screens before reaching the desktop and won't boot:

System Restore via WinRE: Troubleshoot > Advanced Options > System Restore
Startup Repair: Troubleshoot > Advanced Options > Startup Repair
Command Line Repair (see code block below)
Reset This PC: Troubleshoot > Reset this PC (keep or remove files)
Fresh Windows Install from USB as a last resort

KERNEL_SECURITY_CHECK_FAILURE Deep Dive

This stop code (0x00000139) indicates a critical data structure was corrupted — often caused by:

Outdated or incompatible drivers (especially after Windows upgrades)
Malware or rootkits
Overclocked RAM running at unstable speeds

Fix path: Safe Mode > DDU to remove GPU drivers > fresh driver install > disable XMP in BIOS temporarily to test RAM stability.

MEMORY_MANAGEMENT Deep Dive

Stop code 0x0000001A points to RAM corruption or addressing errors:

Run Windows Memory Diagnostic and MemTest86
Try running with one RAM stick at a time
Ensure RAM is installed in correct slots (check motherboard manual for dual-channel configuration)
In BIOS, disable XMP/EXPO to run RAM at stock speeds and test

My PC Blue Screened for the First Time — What Now?

A one-time BSOD is often not cause for alarm. Common triggers:

A temporary driver glitch
A Windows Update that needed a forced restart
A one-time power fluctuation

Actions: Note the stop code, run sfc /scannow, and monitor for recurrence. If it happens again within days, follow the full diagnostic steps above.
