Fan makes a loud noise when starting sometimes

Hi - bit of a noob question really:

When I switch my PC on, sometimes the fan makes a loud noise when starting - it doesn't boot when this happens.... so, I switch it off, and switch it on again and then it's silent and boots up.

Sometimes I have to switch is off and back on a few times so the fan stops making a loud whirring noise (sounds like it's whizzing away) before it'll be silent and boot correctly.

The fan is a Cooler Master GX 750.

Any ideas? All help appreciated. Thanks!

Check to see if no cables are obstructing the fan.
