hey,
The blue screen ( blue screen of death) means that the laptop suffers some hardware problem.
Did you had the time to make a screenshot or write down the info on the screen? In a BSOD is Always some info.
You sayed that you had no sound? it could be that. But it would not make a laptop refusing to start up.
Most of the time a BSOD appears you'll see problems at the main PCB or hard drive , ram ....
What you can do:
Do you have the info on the blue screen?
Did you tried to boot up in save mode or with a live cd?
Kind regards,
Kevin
