I have updated the BIOS. The issues are still there.
All of the issues relate to Disk 0. Disk 1 (C:) I can use just fine.
I replaced the SSD in Disk 0 with a new SSD but the issues are still there.
Now I will update the driver as you suggest. How do I identify which driver(s) to update?
The system event log has lots of errors of this type:
A corrected hardware error has occurred.
Component: PCI Express Root Port
Error Source: Advanced Error Reporting (PCI Express)
