How can I stop my laptop’s processor fan from running at high speed ALL the time and preventing boot up?

My Compaq Presario SR2010NX, when turned on the processor fan runs at high speed all the time. Hence, the computer will not boot up at all. I disconnected CD drive and all external ports and still same thing. Took hard drive out and it works fine in another computer. CMOS battery is ok. Not sure why it does this. Owner said it did it sometimes and rebooted and it stopped. Now it does it all the time. Any suggestions would be appreciated.
