Hello, i have an issue with my Asus X550LN-XO062D. It wont boot into windows, instead it either shows a black screen or some random colored blocks. In either case it shuts down after appox. 10 seconds. Also, the bios doesnt seem to recognise the hard drive anymore. The issue occured when i attempted to restart my laptop in order to switch from windows 10 to windows 7. I have managed to get it running and booted a couple of times, but had no luck afterwards... Could it be just a loose connection or is my hard drive dying (after only 3 months of usage)?
