Analysis: the data cable of the hard disk may get knocked
when installing the CD-ROM, which leads to poor
connection of the hard disk data cable, or the master and
slave jumpers on hard disk and CD-ROM are wrongly
set.
5
The system
cannot be
booted after
replacing a
CD-ROM.
Solution: check the data cable of the hard disk and the
IDE connectors on hard disk and motherboard first; if
there are no problems, then check the master and slave
jumper setting. You may detect that the hard disk and
CD-ROM are connected with different data cables while
their jumpers are all set to master; thus, the hard disk
cannot be booted. Set the CD-ROM jumper to slave and
then re-install it.
Analysis: make sure the PCI card functions normally;
re-insert the PCI card or insert it into another PCI slot to
see whether it is normal; find out the power type in use
(AT or ATX); find out users’ requirement for the PCI card
voltage.
6
No PCI card can
be detected after
entering the
system.
Solution: if the PCI card functions abnormally, replace it
with a new one; if it functions normally when re-inserted
or inserted in another PCI slot, then there is something
wrong between the PCI card and the slot. If AT power is
adopted and the PCI card requires 3.3V voltage, then the
AT power shall be replaced with ATX power because AT
power cannot provide 3.3V voltage. (Suggestion: when
purchasing power supplies, please check whether the PCI
card in use requires 3.3V voltage or not).
Analysis: devices are not connected; no drivers are
loaded; devices are broken.
7
No peripheral
devices can be
detected.
Solution: check whether the cable between the device and
the motherboard is normal; if it is normal, replace it with
a new cable to make sure the connection is OK. Re-install
the device driver and check whether it can be recognized;
check whether the device is normal; if the device is
normal, then check whether the device is compatible with
the motherboard.
