A repeated stop error at the same startup stage needs a different plan from a one-time crash. Repeated forced restarts can obscure the first useful error.
Protect your files first
Back up important files when possible. If the drive is encrypted, locate the BitLocker recovery key before recovery changes. Stop if storage appears to be failing or this is a work or school managed PC.
What to record
The code on each cycle, whether it changes, Windows RE access, drive visibility, and the last known successful startup.
The exact message, Windows version, and whether the desktop still opens matter more than a guess based on the symptom name.
Try these safer checks
Photograph the screen, note whether Safe Mode or WinRE works, and compare the exact code with the official bug-check reference. Preserve files before recovery changes.
Change one thing at a time. After each check, see whether the same symptom returns and write down what changed.
When to stop and get help
If the drive disappears or Windows RE cannot access it, contact the manufacturer or a data-recovery professional.
If this is a work or school device, contact its administrator before changing managed settings.
Keep track of your checks
