Car doesnt start

sometimes my car doesnt start, it make no noise when i try to turn it over. is it the starter solinoid or the starter

It could be the battery, the charging system, a cable connection, the ignition switch, the starter solenoid, a parasitic drain (on the battery), the neutral safety switch, the security system, the Passkey system, or a host of other possibilities.

You’ve given us nothing to work with here.

To start with, what’s the year, engine, and mileage?
How does it start when it does start (strong or weak)?
How old is the battery?
Has anyone checked the cables?
Are there any particular conditions under which this happens?

It’s power to the starter solenoid isn’t adequate.
