There may be a bad driver installed.
Some drivers can cause the operating system to crash or freeze. If the freezes started to occur shortly after a new driver was installed, then that is the likely cause of the problem. To fix this, restore the system back to before the driver was installed; in Windows, this is performed via System Restore.
There is no sound coming from the speakers.
Speakers may be broken.
If no sound comes from the speakers when sound should be heard, the speakers may be faulty and probably need to be replaced. First, make sure the sound is not on mute or at a very low volume. If the sound is not muted and no sound is produced, try plugging headphones into the computer. If the headphones work, this means the sound card is functioning properly and doesn't need to be replaced. At this point, the most likely cause is the speakers, which need to be replaced. See this guide to see how to replace the speakers.
