Hi I hav bought lenovo ideapad Y450 anout 8 months ago. Few days ago when i started my laptop, a humble sound came from it and screen displayed multicoloured lines for few seconds, then laptop worked fine. But yesterday when i started it, nothing is displayed on screen. i heard sound of windows login screen but display was blank. so can anyone help me what is the problem?
