I tried all over Google and can't find ANY help whatsoever. It all started yesterday when my laptop (Dell Inspiron 15 7559 w/ Windows 10) blue-screened and restarted (Error code: DRIVER_POWER_STATE_FAILURE) It restarted, and once it did, I couldn't connect to my Wi-Fi anymore. No Wi-Fi options appear, only VPN and Dial-Up. It still crashes every now and then, with the same error code.

I stayed up all night trying to repair it, and nothing worked. I just want to kill myself now. Some help would be GREATLY appreciated.
