- Could be the power supply, but it's also possible that you've blown the 1488
- RS232 driver chip in such a way that it is shorting out the +/- 12 volts. You
- could test this by (carefully) unplugging the main board power connector and
- then power up the system and see if the fan spins happily.
-
- If you are not completely comfortable with such activities or are unwilling to
- take the risk that the power supply may decide to take out your hard drive or
- other peripherals when you do this, seek a service center or technician...
