Laptop keeps blue screening on windows 10

What does the blue screen actually say? The stop code near the bottom (something like DRIVER_IRQL_NOT_LESS_OR_EQUAL) narrows it down a lot, so take a phone photo next time. Meanwhile, think about when it started, a new driver or update is the usual trigger. Run the Windows Memory Diagnostic from the start menu to rule out RAM, and sfc /scannow in an admin command prompt. Windows also saves crash files in C:\Windows\Minidump, and a free reader like BlueScreenView or WhoCrashed will often name the driver that caused it.
