Hi @Giu7 

Welcome to the HP Support Community! We're here to help you get back up and running.

The error code “b8536646” does not match any known Windows system error, driver fault, or diagnostic code. It may be a unique identifier from a third-party application, internal log, or crash dump.

Here’s how to interpret and troubleshoot it:

What this error might be:

• Not a standard Windows error code: Windows system errors typically follow formats like 0x0000007E, 0xC0000005, or named codes like DPC_WATCHDOG_VIOLATION.
• Could be a crash dump ID or event log reference: Some applications or Windows itself may generate internal identifiers for tracking specific failures.
• May appear in reliability history or Event Viewer: If you saw this in a crash report or reliability monitor, it’s likely a reference ID—not the actual error cause.

What you can do next:

Check where the error appeared

• Was it in Event Viewer, Reliability Monitor, or a blue screen?
• If possible, share the full message or context around the code.

Run diagnostics to find the real cause

• Open Event Viewer (Windows + X > Event Viewer)
• Go to Windows Logs > System or Application
• Look for critical errors or warnings around the time the issue occurred

Use HP Hardware Diagnostics

• Download: HP PC Hardware Diagnostics UEFI
• Run full system tests to check for hardware faults

Check Reliability Monitor

• Press Windows + R, type perfmon /rel, and hit Enter
• Look for red Xs or critical events
• Click them to view detailed error messages

If you can share where you saw “b8536646” or what issue it was tied to (e.g., crash, freeze, failed update), I’ll help you decode it and find the actual root cause.
