Your PC blue-screened. Find out why — right now.
Drop your Windows crash dump below. The analysis runs 100% in your browser — the file never leaves your computer, there's no size limit (yes, even the multi-gigabyte MEMORY.DMP), and the verdict comes with a step-by-step fix plan.
Drop your crash files here
Minidumps, a whole folder, a .zip of dumps, or the giant MEMORY.DMP — no size limit, because your files are read right here in the browser and never uploaded.
Choose file(s)How it works
1
Read locally
Your browser reads only the byte ranges it needs from the .dmp — that's why huge files are instant and private.
2
Decode & diagnose
We decode the stop code, its four parameters, the driver list and the crash stack, then match them against our driver knowledge base.
3
Fix it
You get a plain-English verdict with an honest confidence rating and a fix plan ordered by likelihood — with official vendor links only.
Why trust the verdict?
Classic tools blame ntoskrnl.exe — the Windows kernel — for nearly every crash, because it's always on the stack. That's like blaming the road for every car accident. WhyCrashed weighs third-party drivers above core Windows files, shows you the evidence trail behind every verdict, and tells you honestly when the dump doesn't contain enough to be sure.
