How do I get the sound back on my computer. Don't know why it stopped. But it did. How do I cure this problem? Thanx?

check the volume button on the bottom right. if you don't see a volume button, click the arrow icon and there should be a volume button there. if you have clicked the volume and the volume is on maximum and there is still no sound coming from the speakers, righ click the volume icon and click properties. click the audio output tab (or speakers tab) and check to see which audio output is set to default. right click on your speakers and click set as defualt and it should work. if nothing works then check your speakers for hardware defects. if you have external speakers, check the cable to see if it is correctly plugged in.
