A blue screen is not a breakdown, it is a safety stop. Windows detected something abnormal and halted before your data could be damaged.
So the question is not "how do I get rid of the blue screen", but "what caused it". A single blue screen, once a year, deserves no worry at all. Repeated, it always points to a specific cause - and in our experience it is almost always one of the five below.
The message shows text in capitals such as MEMORY_MANAGEMENT, CRITICAL_PROCESS_DIED or PAGE_FAULT_IN_NONPAGED_AREA, sometimes with a .sys file name alongside. Photograph the screen : that code shapes the whole diagnosis, and the file name often names the guilty driver outright.
If the screen goes by too fast, the history is still there : the Windows Event Viewer keeps a record of every stop, with its date and its code.
This is the most common cause. A badly installed graphics, network or printer driver produces repeatable crashes - often when launching a game, a video or a print job.
If the blue screens started after one particular installation, uninstall that driver and reinstall the official version from the machine maker's site, not from a third-party download site.
Rarer but very real. System Restore or uninstalling the latest update, both reachable from the recovery options, take the machine back to its earlier state without touching your documents.
Codes mentioning memory - MEMORY_MANAGEMENT, PAGE_FAULT - often point to a faulty memory module. Windows has a built-in test, the Windows Memory Diagnostic, which checks the memory at startup. A faulty module produces random crashes with no apparent logic : that is the characteristic symptom.
Codes such as CRITICAL_PROCESS_DIED or INACCESSIBLE_BOOT_DEVICE suggest a drive problem. This is the most urgent case of all : if the drive is dying, every further start-up reduces your chances of recovery. Back up your documents immediately, before anything else, as explained in recovering files.
Blue screens that only happen under load - gaming, video editing, a long video call - and never at rest suggest overheating or a power supply near the end of its life. A thorough dust removal settles a share of these cases.
Start the machine in safe mode, which loads only the bare minimum. If the blue screens disappear entirely in that mode, the cause is software - a driver or a program. If they continue, it is hardware, and you should look at the memory, the drive or the power supply.
Do not install a utility promising to "repair blue screens" : no software repairs a memory module or a failing drive. And do not reinstall Windows before your data is safe - that is the mistake that turns a repairable incident into permanent loss.
The error code, the date of the first crashes and the context they happen in are often enough to pinpoint the cause before the machine is even opened. We offer a free diagnosis in Lyon and across the Rhone.
No. The stop exists precisely to avoid corrupted data being written. That said, if the blue screen comes from a failing drive, that drive threatens your files quite apart from the crash itself.
No. An isolated incident after an update or a power cut is ordinary. It is repetition, especially in the same circumstances, that points to a cause worth finding.
Only if they come from software. With faulty memory or a failing drive, the crashes will return identically on a freshly installed system.
