Hard disc error and no fan.  When I start computer help

Greetings @0825 

It looks like you may need to replace the system disk if you see a "no system disk" error at startup.

Are you seeing any other error messages at startup such as a Secure Boot violation? A system startup Secure Boot error would not be a system disk failure issue.

I don't know why your PC's fans are not active.

Check your PC's hardware using HP Diagnostics as follows:

Start the PC. Repeatedly tap the "ESC" key.

Select "F2". Run extensive system and component tests to confirm: a drive problem, a memory problem, or other component problem.

You might have to replace the system disk and then reinstall Windows.

A HP Cloud recovery option might be available. You would have to provide your PC's Product Number to check this option.

Data on the current system disk might be recoverable if you are not using Device encryption (BitLocker).

Do you have the BitLocker recovery key if you are using Device encryption?
