Hello JU$T1N, If you were to take a read on his first post he says he ended process on the wrong process and now certain parts of his sound does not work correctly actually not at all. Not knowing the process that was ended is a problem. If I knew what the process was I could tell him exactly how to restart it. But5 alas I do not know so I can not tell him. There is another way I believe to fix this but he needs to have a disk made up with Service Pack 2 slipstreamed into it and made boot able so he can boot to it and go thru the install and do a repair of his system. This only works if you have an OEM Microsoft XP home install disk with nothing slipstreamed into it like SP1 etc and you need his system restore disk just for the image file for the system tracks and burn all of this to a new cd.
Running sfc /scannow will do no good in this case I have tried it.
What might help is the instructions for making the special disk. I do not know if it will work but I will send it to him anyway. Please backup all of your data before starting this. I will send two different sites, one for the slipstreamed disk and the other for how to do a repair You are going to need a original Windows OEM Install disk for thisprocedure, one tip if you can find one that already has service pack 2 installed you are half-way there, all you have to do is follow theinstructions from after the slipstreaming on. Oh you have to copy this whole disk to your hard drive where the directions say in Slipstreaming.

On the bootable disk the only way you will know if it is succesful is if it boots from starting your computer. If it does not boot you have a coaster.
