Well, be careful when using the dip switches. What counts
is not matching the visual positions shown in the manual,
but the logical intent. Make sure the switches are set to
ON or OFF, as appropriate. If the dip switch is inserted
upside down, then you would need to invert the switch positions.
If it is a problem like that, you might assume you've set the
switches to 100Mhz, when in fact the switches read 220MHz.
A high overclock could be causing an instant overheat and
shutdown via the Asus CPU overheat safety feature.
