I have a Lenovo G470, Intel Core i5 2450M, 8GB RAM currently running on 64-bit Windows 8 Pro. During the course of installation I've had a lot of issues including a BSOD that won't allow me to enter the OS which in return I had to re-format and re-install the OS. Currently the OS is successfully installed but noticed that when I restart my laptop, it won't load any of my drivers including wireless, sound and I can't adjust my brightness whatsoever. It went back to normal only when I made a proper shut down. When I restart my laptop again, the same thing happen. Could it be that my RAM is almost at the end or could it be a different problem?
