Please let me know what is your motherboard brand and model. Also have you tried updating the chipset drivers from the OEM?
I have gigabyte b75m-d2v.
Yes i tried them and it is older drivers, on gigabyte site, i prefer actual drivers from intel.
You would have the latest chipset drivers available from Intel since you installed the latest chipset software, these devices that you mention are provided by Microsoft* and those would be the latest versions, those are to provide support for those older platforms some date back to 2006 or so.
Okay so these are not important, thanks.
