Problem : No Audio when playing an audio CD in the DVD drive

This is one of the common problem, during a new DVD drive installations. May be you did not connect the 4 wire CD audio cable between the DVD drive and the sound board. If so, the cable may be reversed or defective. Of course, if your are still using your original CD-ROM/R/RW drive and the CD drive is connected to the sound board, there will be no CD audio from the DVD drive. If the DVD drives audio cable is connected to the sound board, make sure that the CD audio input of your sound boards mixer applet is turned up to a reasonable level.

If you wish to continue using an existing CD drive as the CD audio drive, then you can still use audio from the DVD drive by using a patch cable to feed the headphone output signal from the drive to the sound cards line in the jack. Then, adjust the sound cards line in mixer so that you can hear audio from DVD headphone. Also, you can upgrade the sound card to a model that provides two different CD audio channel inputs.

USB pointing devices do not work in Safe Mode

After you try to start your computer in Safe Mode, your computer may not respond to any keyboard commands, or you may receive an error message such as "Windows did not detect a mouse attached to a computer,You can safely attach a serial mouse now". The problem occurs if you are using a USB keyboard or mouse, But your system BIOS does not support USB devices in the real mode. Windows does not support the use of a USB keyboard or mouse in Safe Mode or in real mode unless the computers BIOS supports these devices. To work around this problem, use a standard keyboard or mouse instead of a USB keyboard or mouse. To correct the trouble permanently, upgrade the motherboards BIOS to a version that provides real mode USB support.
