Hello fellas, new guy here. I own a Lenovo z50-75 laptop FX-7500, R7-M260DX running on Windows 10. The problem I get when I safe boot in device manager is the one showing in the attached image. Also, when I restart my laptop, I get the window showed in the other image, and my screen flashes black for about 10 seconds and then its all fine until the next time I restart it. In addition to that, today when it happened all usb ports and the ethernet port were not working at all, until I restarted for another time. Device manager says all drivers are up to date, and I havent found anything regarding this issue in Lenovo's support website. Thanks in advance for your help.
