Hi all, i am facing a problem in Win 8. I have a laptop with Nvidia 8400M GS and I installed Win 8 on it. Also installed the latest Nvidia Drivers for Win 8. Now the problem is that sometimes while opening some folders the screen flickers i.e it shows "D: Not Responding" many times in quick successions and kinds of just hangs for about half a minute. Anyone else is facing the same problem??...Any solution for it??...I wud not like to work without the drivers as then I cant play HD videos. So please help....
