Your PC Ran Into a Problem — Windows Error Fix

What Does This Error Mean?

Note the stop code shown on the blue screen (e.g. CRITICAL_PROCESS_DIED, MEMORY_MANAGEMENT) — it tells you exactly what failed. If it happens once, restart and monitor. If it keeps repeating, update all drivers and run Windows Memory Diagnostic. A stop code with DRIVER_ in the name almost always means a faulty or outdated device driver.

Affected Models

Windows 11
Windows 10

Common Causes

Outdated or corrupted device driver (most common cause)
Faulty RAM causing memory errors
Corrupted Windows system files
Overheating CPU or GPU causing a thermal crash
Failing hard drive or SSD with bad sectors

How to Fix It

Note the stop code

The blue screen shows a stop code (e.g. CRITICAL_PROCESS_DIED, IRQL_NOT_LESS_OR_EQUAL). Search OnlyErrorCodes.com for that exact code — each one has a targeted fix guide.
Update all drivers

Open Device Manager → View → Devices by type. Right-click each device → Update Driver. Pay special attention to GPU, network adapter, and chipset drivers. Download from the manufacturer's website for best results.
Run Windows Memory Diagnostic

Press Win + R → mdsched.exe → Restart now and check for problems. Windows runs a full RAM test on the next boot. If it reports errors, replace the RAM module.
Run SFC and DISM

Open Command Prompt as Administrator. Run: sfc /scannow — wait for it to finish. Then: DISM /Online /Cleanup-Image /RestoreHealth. Restart. This repairs corrupted system files that cause random BSODs.
Check for overheating

Download HWiNFO64 or Core Temp and check CPU/GPU temperatures under load. Normal CPU temps are below 90°C. If temperatures are higher, clean the PC's vents and heatsink with compressed air.

When to Call a Professional

If Windows Memory Diagnostic reports errors, the RAM module needs physical replacement. If CHKDSK finds bad sectors on the drive, replace the drive immediately and restore from backup.

Frequently Asked Questions

PC ran into a problem once — should I worry?

A single occurrence is usually not serious — a one-time driver glitch or cosmic ray bit-flip can cause a BSOD. If it repeats within a few days, update your drivers and run Memory Diagnostic.

Blue screen every day — what is causing it?

Daily BSODs almost always point to a driver, RAM, or overheating issue. Note the stop code each time — if it is always the same code, search for that specific code's fix. If different codes appear, RAM or hardware instability is more likely.

Blue screen after adding new RAM — how to fix?

New RAM can cause BSODs if it is incompatible with the motherboard or not seated fully. Recheck that the RAM sticks are fully clicked into their slots. Test with one stick at a time to isolate a faulty module.
