SOLVING !

5. hard disk not detected.
1. go to the BIOS setup, & change the disk controller
setting from AHCI to IDE.

6. cant hear any sound from computer
1. Try using the Playing Audio
troubleshooter to fix the problem. It checks
for common problems with the volume
settings, the sound card or driver, and the
speakers or headphones.

7. 2.Many computers have three or more jacks
that connect to a sound card or sound
processor, including a microphone jack, line-
in jack, and line-out jack. The speakers
should be plugged in to the line-out jack. If
you're not sure which jack this is, try
plugging the speakers in to each of the jacks
to see if any of them produce sound.
