Laptop crashed Need Immediate Help Please


Oct 6, 2013
So last night I was using my computer to play music for friends. My computer was hooked up to a speaker system. Someone went to change the song on youtube and the screen went black and it crashed. When I went to reboot it, 3 lights flash and the fans max out, then it begins to beep. It beeps for about 2 seconds then pauses then continues. It beeps about 21 times before shutting down. Also a quiet crackling sound can be heard at intial startup, other than that no sound is heard until the fans start and the beeping. Please help, thanks Peter
