Hello
Thank you for posting in Q&A forum.
The WHEA_UNCORRECTABLE_ERROR (124) with the faulting thread ffff948cdceb9080 and process name smss.exe (Session Manager Subsystem) indicates a critical hardware error that occurred during the boot process.
As you mentioned, you have added a new SSD, please temporarily remove it so we can narrow down the issue.
Here are some steps to help diagnose this issue:
- Analyze the Error Record
• Use the Windows Debugger (WinDbg) to analyze the error record. You can use the !errrec command with the address provided: cmd !errrec ffff948cd82d5020
• This will give you more details about the specific hardware error.
- Check Hardware Components
• RAM: Run a memory diagnostic tool like Windows Memory Diagnostic or MemTest86 to check for faulty RAM.
• CPU: Ensure your CPU is not overheating. Check the cooling system and thermal paste.
• Storage: Run a disk check (chkdsk) to ensure your hard drive or SSD is not failing.
I hope the information above is helpful.
If you have any questions or concerns, please feel free to let us know.
Best Regards,
Daisy Zhou
