Problems......

Everything has just came up all at once. The starter is in its last days and i plan on getting it rebuilt Friday. After startup, my car makes a weird noise almost similar to a supercharger whine. After about 5 seconds the noise is gone. My dad seems to think it might be the throw out bearing or the oil pump. Has anybody had this problem?? All help is appreciated.
 
check bearings maybe..... alternator, or idler bearings.... somthing like that... it could be once they spin and heat up they expand and noise goes away....

just a thought...
