Hello. I use GT70 barebone laptop within GTX 870M. My OS is Windows 7 x64 SP1. The driver's version is 340.52.

I have a problem. My laptop hangs at Welcome Screen for 30 seconds. During that time the laptop's screen blinks for 1 or 2 times. At the same time the laptop's power indicator turns to red for 4 or 5 times which means NVIDIA GPU is active. I think this process delays my post-boot time.

Anyone have experienced something like this? I want to know if this is normal or not. If not, I will try older and newer drivers. By the way do you know how to backup my NVIDIA profile settings? I want to perform clean install if I have to.

I am new to mobile NVIDIA card but I never experienced something like that while I use mobile AMD card. Thanks in advance.
