hi, About 2-3 years ago my older brother put together a computer hiself from separate bits.Everything was fine however after about 6 months the speaker system on the screen stopped playing sound so I connected external speakers.They worked fine.Then the computer started showing a safemode page and no matter which option I chose it would restart and go back to the same page, so i sent it off to get it fixed and he had to replace the big box thingy inside (excuse my bad english) so we got it back but there was no sound and at the moment i cant contact my brother so i was wondering if anyone had any suggestions? -x-lara-x-

Take it back to the people that worked on it.

cant really tell for sure what work you had done on it. it might needs the sound drivers (software) installing. Have a look in Device Manager and see if anthing is listed with yellow or red markers (those markers indicate a problem)

Sounds like (big box thingy) is the power supply. Old power supply could of toasted the onboard sound system....but first.. Make sure the speaker is plugged into the correct socket.....(green)....then check drivers. Try the speakers on a different system. W.L.

I think it was because they had to wipe the memory it wiped the software off too. I cant remember any disc with it though because my bro did it. I was wondering if anyone knew a cheap and easy way of getting knew audio software? -x-lara-x-

The first thing you have to identify for anyone to be able to help you is identify the Operating System. MS-Windows? Apple OSX? Linux? Your getting responses which are assuming you have a Microsoft Windows based system, which is a reasonable assumption since about 90% of Personal Computers are running MS-Windows. Next, you have to try to find out what that Operating System says about your sound card. For Windows, it means looking at the Device Manager and seeing if there is a sound card listed in the list of devices. If there is no sound card listed, then the Operating System does not detect a sound card on your computer and that is why you have no sound. If there is a sound card listed and it's "properties" claim that it is "working normally", then you have some kind of connection problem with your speakers. Like maybe the speakers are plugged into the wrong place, or something like that.

In any case, make sure your speakers are plugged into the proper jack (usually there is a green ring of plastic around it), the power adapter for the speakers is plugged into AC power and the speakers, and the speakers are switched on. " the speaker system on the screen stopped playing sound so I connected external speakers. " I'm assuming you don't have a laptop or notebook because there is no "big boxy thing" in a laptop. Therefore you must have a monitor with speakers built into it. Did you or your brother or whoever install a sound card at that point? If so, or in any case, you may have two sets of sound ports - built into the mboard, and on a card in a slot. If yes, you need to plug into the sound card speaker port, not the onboard (built into the mboard) speaker port. In that case, if the sound does not work, you need to get the driver software for the sound card, not the motherboard sound drivers. Unplug or switch off the AC power to the case, open up the computer case (see below), remove the sound card, and tell us if you see a model number on the sound card - e.g. if it is made by Creative/SoundBlaster, it has a CTxxxx or a SBxxxx model number on it. If you don't see a model number, tell us what is printed on the largest chip on the sound card. ....... If you have only one set of sound ports, if they are built into the motherboard you must identify the computer. (If they are built into the motherboard, they are in the rectangular area where most of the ports are. If they are on a card in a slot, they are in a narrow rectangular slot space, by themselves - in that case you need the sound drivers for the sound card, not the motherboard - see above). You need to tell us what the model of your brand name system is, or if you have a generic system, what the model of your motherboard is. If your computer is a brand name system, e.g. Compaq, HP, Dell, Gateway, emachine, it's model number is on a label on the outside of the case somewhere. If you see no brand name like that, or similar, on the case, if this is a desktop or tower computer, you need to open up the case and see if you can find the model of the motherboard, the largest board inside the case, printed on it in larger characters, often between the slots or near the center of the motherboard. When looking at the front of a tower case, it's the left side of the case you need to remove- there are usually screws you need to remove at the back corner of that side. If it's a desktop computer, you need to remove the top of the case. We need a better description than "big boxy thing". If it was the computer power supply, it's very unlikely the contents of your hard drive had to be reloaded. If it was the hard drive, or if the hard drive was re-loaded, yes it's quite likely someone re-loaded Windows on it and the sound may not work until drivers for it are loaded. If you have only one set of sound ports, and don't have a sound card, we need your brand name model or your mboard model before we can tell you where to get the drivers. ... You're using memory to refer to the wrong thing. Data can be stored pernamently on your hard drive(s) or temporarily in the memory modules - ram - installed in your motherboard, but whatever data is stored in the ram varies constantly according to what you are doing, and the data stored in it is lost when you shut down the computer.
