Windows 11 Has Been Blue-Screening Once a Day Since August 26
Asked by

My Windows 11 PC has started crashing about once a day, beginning around August 26. The crashes happen in different situations, and I'm not sure whether a recent update or something else triggered them. Reliability Monitor hasn't clearly indicated a hardware problem. Today's report shows an unexpected shutdown with a BlueScreen event, bug check code D1, and OS build 10.0.26200. A dump file named 083126-30015-01.dmp was created. I can provide reports from previous days if needed, but they appear to be very similar. Some of the original diagnostic text was in Italian, so I translated parts of it manually.

A D1 bug check usually points toward a faulty or incompatible driver, although bad hardware can also trigger it. I’d start by updating or clean-reinstalling graphics, chipset, network, and storage drivers—especially anything changed around the time the crashes began. Running sfc /scannow is also reasonable for checking damaged Windows system files, but it probably won’t identify the underlying driver by itself.

The most useful next step is to inspect the crash dumps rather than relying only on the Reliability Monitor summary. Check C:WindowsMinidump and copy any .dmp files somewhere else before compressing them. Multiple dumps are especially helpful because they can show whether the same driver is involved each time. If no dumps are being created, enable Small Memory Dumps in the startup and recovery settings, then wait for the next crash.

If this is a desktop, also consider checking the physical components. A RAM stick that isn’t fully seated can cause seemingly random blue screens, even when diagnostic tools make the issue look like a graphics or driver problem. Since it’s a prebuilt system and may still be under warranty, check the warranty terms before opening it. The manufacturer may be able to reseat or test the memory for you.

MellowPine47: It’s a prebuilt desktop that I’ve owned for at least a year, possibly closer to two. I’m nervous about opening it because I don’t want to void the warranty, so I’ll contact the manufacturer first and ask whether I’m allowed to inspect the RAM.
