"could a blown one stop a pc from turning on?" - any faulty component can stop a pc from turning on.
"if you can replace them " - some things you need here:
1: a new resistor. Fortunately, they only cost $3 for a pack of 50
2: to know if that's the only component that's blown. Usually components do not blow on their own - there's usually a reason behind it blowing that probably won't go away by replacing the resistor.
3: someone who knows how to solder those components without ruining the rest of them.

My guess is that you can only fulfill one of the three requirements, so you overall answer is no.
