Hi, I have a toshiba c50 and about maybe an hour ago, it turned off and the display will not come on. Usually, a white light comes on but when i turn it on, the light to the power button comes on and two out of three lights come on, the one on the left and the one on the right but the one in the middle does nothing and the number lock light comes and you can hear the laptop begin to start but it sounds like as if it is stalling. I've tried taking out the battery, pressing f8, f12, basically everything. Any suggestions? Thanks so much
