I installed windows 7 about a month or two ago. I notice this issue but it was not often and depended on the day. Now it is everyday. When I try to click on an icon, any icon, I have to click it 2-4 times before it registers. I thought it was a game which is known to have latency problems, but it does it before and after even going into the game. I pull up the favs in ie and have to click those twice to go to website. An icon on the desktop will not highlight w/o clicking several times. I have checked the logs and there are some issues with the nvidia SATA controller. But these are not as often as the problems are all the time. When in the game, the keybord buttons work as normal but sometime they do weird stuff too, the toon moves the wrong way. I have an older Asus MB P5N32SLI-plus, IntelQ6600, BFG 8800gt, 6 gig super talent but i think i have 2 gig one latency and 4 gig diff not sure, hitachi 250gb sata drives. I let windows install all drivers and update them. There seems to be no conflicts in the device manager. I don't remeber the PC doing this in Vista. Should I use the drivers from the specific manufacturer instead of Windows or better to let it do its thing? Is it the memory freaking out or the sata controller or maybe the video driver. I am thinking one of those but how do I narrow down? Thanks for any help!
