The thing is, I dont actually know what driver I have to download.
Looking at its properties I have,
Device Description : PCI Device
Location Paths : PCIROOT(0)#PCI(0A00)#PCI(0400)
Physical Device Object Name : \Device\NTPNP_PCI0023
location information : PCI bus 1, device 4, function 0
The Install date is the 3/3/2012. which was the day I put my newly psu in.
Maybe its something to do with that?
