Hello, My windows 8 system not turning on at all. Its been a month since I installed windows 8 on my computer, now when I turn on the computer the CPU makes normal sound with single beep at starting then the fans runs casually like before, but nothing displays on the screen. Only a blue screen appearing for long time. No key from keyboard works to get home screen and nothing happens with mouse clicks. What should I do now to fix this issue permanently. My system turned off from week due to this reason, try to provide a fix for my problem at your earliest. Thank you for any response.
