cpu drivers amd x2 6000 on vista 32bit

[dangerousmouse]

been running vista home prem for about a month now, but this is really bugging me.

following installing windows, i installed drivers for cpu, motherboard etc, etc... that are on the cd that came with mobo. a lot of the time i got messages saying, only works with xp, 2000, 98 etc... downloaded a load of the vista drivers and got that sorted.

only problem is, in device manager it is listing 2 processors.
AMD Athlon(tm) 64 X2 Dual Core Processor 6000+

one of these is reported to be working fine, but the other isnt.

This device cannot start. (Code 10)

Click 'Check for solutions' to send data about this device to Microsoft and to see if there is a solution available.

have been onto msi, amd windows update etc... but cannot seem to get it working.

is there something i am missing?

thanks in advance.

EDIT:
mobo: msi k9a platinum
