I have just spent the last 30 hours of my awake life putting in a new hard drive and re-installing all my software, drivers, and updates on my gateway NV51B91u Notebook. I was just about to do the last thing and flash the BIOS and in the middle of flashing the bios THE POWER WENT OUT! Yes, the power went out! What are the odds! Someone hit a pole from the snowy roads and knocked it out and after the power came back on, I went to turn on the laptop and all that happens is a blank screen and the fan runs. I get no post or BIOS! If anyone can please help me, I will be so greatfull....
