Many thanks Pebbly.
These are the supposed driver errors as found by Driver Detective:
IDE ATA/ATAPI Controllers
Intel(R) 6 series /C200 series chipset family 6 port sata ahci controller - 1c02
Standard ahci 1.0 serial ata controller
Standard Dual Channel PCI IDE controller
AMD High Definition Audio Device
High Definition Audio Device
(7) Intel(R) 6 series /C200 series chipset family PCI Express root port - 1C10
(2) Intel(R) 6 series /C200 series chipset family USB Enhanced Host Controller - 1C26
There is a couple of yellow triangle warnings:
Multimedia audio controller
PCI Input device
I do not know of any 'unplugged' multimedia audio controller or what the PCI input device refers to.
I hope you can point me in the right direction
