Hello I have a few questions about drivers. I recently installed a EVGA GTX 560 and when I put the disk in it said its not compatible I think because I use windows 8 so instead of running compatibility mode I just installed drivers from nvidias website. I read in manual that they recommend running disk. Is it ok that I installed manually from site? Also I downloaded driver manager to check all my drivers and it said that my AMD SMBUS and Standard SATA AHCI Controller are out of date. I checked in device manager and it says they are up to date. Is there any place I can safely download them manually? And what is the best software for checking drivers and is there any free ones. I read forums and people say not to use driver checking software should I just uninstall driver manager and forget about the drivers it said were out of date?
