CPU running very high after Vista upgrade!!

Hi everyone

I have recently installed Vista home premium onto my A7N8X deluxe (rev 2.0) bios 1007 motherboard. I have an XP2800+ with 3gb of ddr400 memory in 200 mhz dual channel mode. The pc boots up etc. but the cpu seems to run at over 90% and often 100% for the slightest operation.

The pc seems stable enough and virtually everything works ok. Vista reports my cpu correctly as an XP2800 and the ram and graphics card are correctly stated.

I just ran a full backup and the cpu was at 95% or more for the entire task! This just does not seem right. Can any one offer me some advice?

Further update: i have looked at system devices in device manager and it states 'no drivers installed for this device' on the following:

programmable interrupt controller
direct memory access controller
numeric data processor
nvidia nforce pci system management

I am aware of a lack of Vista nforce2 drivers for this mobo but i was hoping there is a forum subscriber who has a similar board running Vista who could advise?

Any thoughts very welcome

Wyatt(will pick up any posts after 6:00pm tonight)

Not sure how well it will work but it is the only solution I can find short of upgrading your hardware.

Thanks so far.

I have found this nvidea driver pack

It's for XP so i shall run it in XP compat mode.

I will give it another hour or two before i run it in case any one else can shed any light on it.
