I've been attempting to resolve this issue for days, with no success. I'm fairly new to linux. I don't know anything about reinstalling the kernel (Although it sounds easy from what I've read). The window manager I'm currently using is KDE. I installed the nvidia drivers with pacman -S nvidia, then tried using startx. The screen goes black and my GPU fan comes on at full speed, then the laptop reboots after a few seconds. I also tried installing the proprietary drivers from NVIDIA's website with the same results. I've tried using nvidia-xconfig and bumblebee. The Xorg.0 log file has the entry Code: Screens found, but none have a valid configuration or something similar to that. I would have posted this on the Arch Linux forum but the verification is seemingly impossible in my state.
