How to update drivers

Ok i am trying to tackle a project i havent done with SCCM before and am not sure the best way to go about it.
I have about 200 Optiplex 760s that need the latest Video drivers installed. During my searching I am just seeing how to create a task sequence with the newest drivers however that looks like it is only for a new OS deploy. I am only wanting to update the drivers on an existing OS. 
If someone could just point me in the right directions :)

You will need to make a application package and then push it out.
 
see if there is a silent switch for the driver upgrade installer then just call the exe/msi and target it by making a collection that holds all machines with that driver that you are looking to upgrade. or target it with something like  "model=Optiplex 760" in your collection query.
 
then you can just replace the driver in the database so it will install the new driver on all future builds.
 
hope that helps steer you in the right direction :)
 
 

I kinda guessed that if there was an app for the driver what about if its just an inf?

Looks like this would work:
rundll32 syssetup,SetupInfObjectInstallAction DefaultInstall 128 .\<file>.inf 

What OS?
 
DPInst or PNPUtil may work.  I've not used these to "update" drivers though but don't see why they shouldn't work.

PNPUtil requires the drivers to be on the local hard drive and not a UNC path, at least in my experience.

One way to handle this is to install SCUP 2011
Then you can download update catalog for Dell Business Clients. Import the drivers you want to deploy, and deploy as a Update.
