This is most-likely caused by the second hard disk overloading your
power supply.  The supply generates a power-good signal to the
motherboard.  If the supply is operated at its capacity or beyond,
this signal may occasionally drop, which normally forces a hard
reset and a cold boot of the PC.

You can probably replace your power supply for about $50.  Get one
rated at least 150 Watts, if you're running two hard disks.  If
you've got most of your expansion slots filled, or if you're using
other hungry peripherals, consider a 200-watt supply -- probably
priced about $75.
