need assistance with Intel driver updates!

Version 3

    i have an older computer which continuously states that I need to update the following intel items such as: Intel(R)ICH8R/ICH9R/ICH10R.DO/PCJ Sata Raid stating I need driver update or intel (R)ICH9 family PCI Express Rood Port 3 (Several of these) or Intel(R)82801 PCI Bridge....  , INTEL(R)ich9rlpc INTERFACE CONTROLLER-2916 STATING NEEDS NEW DRIVER,  Intel(r)82566DC-2GB Network Connection, Intel(R)G33/G31/P35/P31 express chipset PCI Express... anyways, what I am wondering, do I need to worry about updating any of these intel drivers or is it possible to update any of them without causing havoc in the computer?  It seems all the drivers in the computer are up to date with the exception of these.  I try to keep everything up to date so the computer runs smoothly, quickly and efficiently.  I would appreciate your input in this matter.  I did try to download one of your Intel software that searched for driver updates but it failed to work.  I have a x64 windows ultimate 7 computer that was updated from a Vista ultimate.   Thank you for any help that you may offer me at this time.  Patti
