Troubleshoot Windows blue screens by recording stop codes and checking drivers, memory, storage, heat, power, and system files safely.
Follow the diagnostic steps yourself, or use Advanced PC Repairs when Windows can still start and you want help identifying supported system conditions.

If Windows can still start, scan for supported Windows conditions related to system files, stability, and performance.
A blue screen appears when Windows stops to protect the system from an unsafe condition. One isolated crash may be temporary. Repeated crashes, restarts, or different stop codes require a structured investigation that separates software issues from hardware instability.
Photograph the screen and record the stop code, named driver, time, and workload. Check Reliability Monitor after reboot for a timeline. The code narrows the search but does not prove a single cause.
Disconnect new nonessential USB devices. Roll back a driver or uninstall a recent utility if timing strongly matches the crashes. Return unsupported overclocking or tuning settings to defaults.
Install supported Windows updates and use the PC or component manufacturer for chipset, storage, graphics, network, and audio drivers. Change one category at a time and retest.
Run Windows Memory Diagnostic for an initial RAM check. Back up data and use the drive maker’s health test if files corrupt, the drive disappears, or disk warnings appear. Intermittent faults may need extended diagnostics.
Confirm fans operate, vents are clear, and the PC has stable power. Crashes under gaming or heavy workloads may relate to temperature, graphics, memory, or power delivery.
Try Safe Mode, Startup Repair, a relevant restore point, and targeted system-file repair before reset or clean installation. Preserve recovery keys and files before consequential steps.
It is a protective stop, but the underlying instability can threaten unsaved work or data.
Different codes can arise from shared causes such as unstable memory, storage corruption, power, or multiple affected drivers.
Get help when the PC cannot boot, contains irreplaceable data, shows hardware warnings, or continues crashing after basic checks.
