[syed_35]

it starts up fine(use seems to be fine) then after sometime it hangs (makes an annoying buzzing sound)then blue screen appers for a second and restarts saying to the top left checking media and promts(efi network 0 ipv4 boot failed something like that)and it has to be restarted by the power button and the same goes on......

I would go to the lenovo G50-45 website and pick up the current windows 10 drivers. (Sorry, the link does not show up) then update the audio driver and the amd video driver.
the graphics card has audio support for the HDMI and it can have a conflict with the laptop audio driver on its motherboard. When this happens you get a buzz sound out of speaker if you have a speaker connected to the failing audio port.
