Both of these were related to PCI.SYS but on further examination it appears to be caused by ACPI Driver for NT. What PCI devices do you have?
Since this is an OS file and there is no update as of yet lets start with a system file check
Run a system file check to verify and repair your system files.
To do this type cmd in search, then right click to run as administrator, then
SFC /SCANNOW
It may need to be run up to three times before successful
Let us know the results from the report at the end
