Hi, I have a Asus F551M Notebook. What happened first was I put the ear phones in the usb the whole machine shut done but check this website and found how to sort that out. Removed battery got static out, she fired up anyways and working normal apart from black screen. Checked with HDMI cable on another monitor but nothing came up. There is no faint light off the screen. So I was thinking it might be the ram? Can't find a replacement online, any guidance or help would be greatly appreciated
