Toshiba satellite freezes at start up!??

on the bottom of your laptop is a place for your ram,if you have two memory chips take one out and restart it,if it works the memory is bad, now if it don't put it back in and take out the other one to see witch one is going bad,if it Still don't work,try changing one for the other,that goes for both sides,,you are three beeps away from memory failure
