I recently reformated my computer with winxp and I have no sound I have tried many things nothing worked I am not sure what my computer is it says node-1 on the front and it says tyco on the soundcard any help would greatly be appreciated.

Did you save your drivers before reformatting? You need to find out what sound card you have and get the drivers for it.

Actually if you reformatted your computer and you have never changed out the sound card.. you should have got a disk with your computer that has all the drivers on it... if you don't then you go to device manager or system information and see what kind of sound card you have... then you go to the internet and search for that driver and install it

By reinstalling the operating system without first identifying your hardware and obtaining the necessary drivers you may have put yourself in a difficult bind. Often the component drivers can be downloaded from the internet and preserved on a floppy, CD-R, flash drive or external hard drive. Unfortunately you need to know who manufactured your motherboard and peripherals (including expansion cards) to locate the web site with the downloads. The manufacturer information can usually be found in the manuals/pamphlets that come with the computer or interrogating the computer before sacrificing the original operating system installation. Unfortunately the label on the front of the case may only indicate the origin of the computer's case, since some computer shops assemble custom built computers with components from a variety of different component manufacturers in the same computer. There's a possibility some of your local computer dealers would be familiar with your system's origins.

Major computer brands often have software in a partitioned off portion of the hard drive that installs the drivers and applications that came with the computer. I'm thinking it unlikely you have this configuration, since it probably wouldn't have resulted in your problem. The issue with those computers is promptly utilizing the provisions for making removable recovery media which would allow the user to recover from a hard disk failure.

It sounds like you need sound card drivers. Check the media that came with your computer for a CD-R or floppy. Sometimes you need to use Windows' "Add or Remove Programs" function, and sometimes you will need to use the "Add or Remove Hardware" function. You will probably need to "browse" to point either of those windows to the sound card driver media in either case.

Make sure that nothing is muted

Do you have a little speaker next to the time in the taskbar?

In control panel, click on Sounds and Audio devices and then the advanced tab

Check to make sure that you do not have Wave and Master Volume muted and that the volume sliders are up

-right click on My computer on desktop and click properties and then go to hardware tab and device mgr.
