Hi AC Bel,
Thank you for reaching Microsoft Community. We're sorry for the trouble this has caused you. I will be asking few questions to know more about the issue.
When did this issue started?
Any changes made on the device prior to this happen?
Can you provide a picture of what the error looks like after turning on your Surface device?
For the meantime, Run Surface Diagnostic Toolkit and make sure to check Windows updates including optional updates if available.
See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)
I need above details in order to provide accurate resolution. I hope to hear from you soon.
Kind regards,
Lavenia
