PCI controller wont go away

I have installed new drivers for the PCI hard disk controller - however the old ones wont go away - saying they can't be removed as they're dependent on the new one. Is there any way to get rid of them? They're causing all sorts of conflicts on startup. Is it better just to reinstall windows?

What about removing them when you are in safe mode?
You can try to disable the PCI controllers you don't want in your hardware profile if they show up in your device manager.  If they don't, sometimes it's easier to just re-install instead of spending hour troubleshooting PCI problems.

Hope this helps.

Yeah, I just wondered if any one had a magic bullet for it...just reinstalling?
Re: disabling/removing them in safe mode - that's the only mode I can get into windows with anyway -, and that's exactly where the problem is - I can't diable or remove them because the ones I don't want each say they are dependent on something else, but it doen't say what. Very frustrating.

The config of the machine - gigabyte m'board with dual pci controllers, and a UDMA HDD and CD drive master/slaved on one.

Any other hints? Otherwise I'll just do the reinstall.
Can you remove the correct ones and then update the drivers on the ones which you can't remove.

I.e. Instead of installing a 2nd set of PCI Contoller(s) you should have updated the existiing one.

Yes, that's what I mean when I say "installed new controller" - updated the one that was there. That's when all hell broke loose - as the other "children" parts didn't update, you can't update them individually, and now I can't get rid of them so Windows can find them itself and install the updated driver. Is it possible to get rid of the current controller while windows is running - wont it crash without a hdd controller? If I can get rid of everything and restart - plug & pray should do the rest...or not...
I'd try redetecting hardware if it will let you from safe mode otherwise you're looking like a reisntall of the OS
Are any of them Intel Bus Master drivers?
