Windows Stop Code / BSOD Lookup
Look up a Windows blue-screen stop code and get the likely cause and next step.
What you paste
Parsed in your browser — never uploadedHow this reads your output
Enter the stop code shown on the blue screen — either the hex value like 0x0000000A or the name like IRQL_NOT_LESS_OR_EQUAL — and the tool returns what it means, the broad category most likely at fault, and the first thing worth checking. You can paste the whole blue-screen line; the code is picked out of it.
What the results mean
- Most likely cause
- The broad category — driver, memory, storage or hardware — that this code most often points to. It is a lead, not a diagnosis.
- Driver causes
- The most common and most fixable. Updating or rolling back a driver resolves a large share of blue screens.
- Hardware / memory causes
- More serious. Codes like WHEA_UNCORRECTABLE_ERROR point at failing components — worth a memory test and a temperature check before spending money.
Common problems and fixes
- The same code keeps pointing at "driver" but I do not know which
- The minidump file in C:\Windows\Minidump names the driver involved. A free crash-dump reader will open it, or note any .sys filename shown on the blue screen itself.
- It says hardware but everything seems fine
- Hardware faults are often intermittent and heat-related. Run a memory test overnight and check temperatures under load before concluding the hardware is healthy.
Frequently asked questions
Does a stop code tell me exactly what is broken?
No, and any tool claiming it does is overreaching. A stop code tells you what kind of failure Windows detected — a driver accessing bad memory, an unrecoverable hardware error — which narrows the search. Pinning it to a specific part still takes the minidump, a memory test, or swapping components.
What should I do first for most blue screens?
Note what changed just before they started — a new driver, a Windows update, new hardware — because that is the fastest lead. Then update your drivers, run "sfc /scannow", and run a memory test. Those three steps resolve the majority of cases.
