From the issue description, I understand you got 80070003 error code while working on the laptop.
Could you answer few questions to help us analyze and understand the issue in a better way:
1. Have you installed any updates from Windows update recently?
2. Are you able to boot to the desktop screen?
3. Have you made any recent any changes on the computer prior to the issue?
