when i was in a skype call i was trying to watch some youtube videos and wasnt getting any sound so i tried unplugging my headset to see if that was the issue but still no sound...so i tried to restart the computer and when it went to reboot i could hear the fans kick on but the screen didnt turn on. let it sit for like 10 min and still nothing, so i did a hard boot to restart and see if i could get into the bios but the screen still wouldnt turn on. any help would be much appreciated...
