No sound on my jump start preschool

I sure hope you kept a recent backup. Something has gone terribly wrong in there. If you didn't keep a recent backup, do you still have the Windows setup disk(s), or the Recovery disk? It sounds like you will need to do one of those. STRONG ADVICE_ DO NOT start to run a Recovery or Resoration disk NOR a backup and then stop it part-way done! I did that recently, and it took me 3 months to find a solution. It deletes all your partitions. Then nothing will work without much research and work. Once you start a recovery from a disk or a backup, let it finish! It may take awhile, but it's worth it. Don't panic. Just do a backup restore or a restoration disk, and any lost data, will be lost. People call using the Restoration CD a "reformat". It gives you a fresh install of Windows. Try to always keep a recent full partitions backup, it's worth it's weight in gold. Feel for you!

replace the power supply

pls try to restore or repair thru backup disk u made when u bought pc

otherwise follow this procedure for restoring the OS without backup disk but data might be lost on C drive only not D or other drives pls take care

reset on the top, and restore on the bottom.

Have you tried restarting your computer? If that didn't work try deleting the program for your sound card and try reinstalling it. If that doesn't work try a system restore, now depending on your operating system the fallowing information my not be accurate. This is for Windows XP Home edition, Click on Start>help and support>system restore. Then it will ask you what date you want to restore it to, then pick a date, then click continue or next and it should restore your system to that date. Hope this helped=)
