Serious Help Needed

Ok, Well, I threw together an old compaq, so I could have a pc at my dads house, well everything went fine, the only problem I had was the onboard sound not working :C...Ive double checked everything twice over, Ive made sure that my onboard audio is enabled in the bios, and Im really stuck...anyone got any ideas??

Does it show up as a hardware conflict in Device manager?

Drivers need updating if not a simple reinstallation. You can easily right click on the MyComputer icon and click the hardware devices button to enter the device manager. Scroll down to the sound and game controllers section and open that up. You should see a yellow mark on something there. You simply right click on any item found and choose the update driver option if you have the drivers onhand for the system.

Thats the thing, Ive already checked that and there was no conflict, but just incase I went ahead and downloaded and installed the latest drivers...and, Im still not sure what the problem is..

Hopefully the onboard chip didn't give out. If it's a driver issue you would first right click on the sound device listing in the device manager and choose the uninstall to see the original drivers removed. After a restart of the system the hardware could then be updated by then installing the newer ones. The problem besides a failed chip would be seeing that the drivers are made active by allowing Windows to copy them fully from a folder where the new drivers were unpacked.

I've had a computer where the onboard sound just died. It would show up in windows and what not, but any time it tried to play sounds, it would lock the system up. I just disabled onbaord and used another sound card and the system was fine. However, this kind of problem is very rare.

Are you sure the Speakers are plugged in correctly?

Checking the connections as well as the jacks on the board itself would help. Generally you still hear something from one side or the other if one was unplugged or a bad connection was there. The amp in your speakers could have crapped out on you though.

Ive double, triple, and quadruple checked all connections, nothing, Ive even plugged in 2 different pairs of headphones, and still nothing, I could buy a 30$ creative, but I really didnt want to do that just for a pc at my dads house....

You either downloaded the wrong ones or the onboard quit on you. With onboard you have the same problem seen with pci sound due to AGP/PCI conflicts that can come up with XP's resource sharing. What model is the system there? Was that purchased before the buyout of Compaq by HP?
