I got my computer half a year ago, and until recently it had been working perfectly, however after my Monitor died I was forced to turn my computer off with the power button and after that it just stopped working properly. Firstly it turns on by showing me the Asus black screen with text under to press either Del or F2 to open BIOS, if I do press it it just stops working completely, if I don't it turns on normally, if I try to restart the computer through start menu it doesn't boot, just shows me the black screen and then I again have to turn it off through the power button, unplug all of the periphery wait a couple of minutes and then it turns on through the same process.
