Hi. I have a lenovo y50 and recently the windows update on windows 10 installed some update and the pc was shut down. When i powered it up again later, the update is being configured screen was up and as i was busy in something else i didn't notice what happened after that. When i got back to it it had a blank screen with leds working and keyboard backlight on. I force quit it and restarted. Then it was stuck on the lenovo logo for quite a while. I again force quit and restarted and then i got a bsod. After that, now when i power it on, the screen is blank with led's powered up and keyboard backlight on. I can't even get the lenovo logo now. Any help please?
