1997 Toyota Corolla Help please

Hi, my problem is,
everytime when I start my car, I hear a squeeking sound. When I turn the wheel, it squeeks, and he more I accelorate, the lauder and faster it sqeeks. I sometimes can hear it squeeking when im at a red light when im driving. I think its my power steering belt. If not, what is it? And how can I fix it?
- Thank you.
