There can be several faillures. If the lights are on then I'd start with ram and after that with graphic card. If not then start with psu.

Here is the link, some of the text is in Danish, but just press the download tab, and all of the useful text is in english.http://www.asus.dk/Motherboards/Intel_Socket_478/P4S800MX/#downloadGlobal
If you already have tried this download, are you sure this isn't the se version of the motherboard?
Regarding the usb and sound; first of all have you installed al the drivers supplied with the motherboard? If you have, then have you connected the internal usb pins to the external ports and tried every usb port including those on the back?
Unfortunately that is what I can suggest at this point... If that doesn't work, and updating the bios doesn't work, then I suggest resetting the motherboard.
Hope this helps

This is your board:
Unfortunately Sound Max is no longer available and you may be able to find the driver at the Asus site I gave you. It would only work for the version of Windows your system came with and, I can't guarantee that. Your easiest and best option at this point, would be to upgrade to a PCI or USB sound card. You can use something like this:
Which is a USB card or, something like this:
There are others available:
Any of these sould work for you and, in the long run, you will be happier with an added card.
Good luck,

Hello there vinod_kundap.

Here's your geek-steer ...

Those beeps you hear is your BIOS alerting you about trouble encountered during the bootup's Power-On Self Test (POST) in the only language she knows ... beeps!

Your motherboard uses Award BIOS, and the only POST result that comprises three beeps is "1 long, 2 short" which indicate:

"Video adapter error: Either video adapter is bad or is not seated properly. Also, check to ensure the monitor cable is connected properly."
  • The "video adapter" is the physical device (aka card).
  • "not seated properly" means the card/cable connection(s) are not fully connected tightly.
Of course, this might not be the trouble at all. It is very common for POST failure indicators to be wrong, it's just the best the poor stupid little glob of circuits can do. But it's probably all you have for now, unless you're aware of any other clues not covered in your question.

Troubleshooting actions based on this result would require opening PC case and physically inspecting all connections, and if still troubled, swapping out the video card with a "known good", or taking it out an installing into a "known good" PC, then let simple deduction determine.

Good luck, and please do post back ...
  • to let me (and interested others) know how things worked out,
  • to provide clarification or feedback,
  • if you have ANY further questions.
Today's the best day of my life ... and NOW you're part of it!
Via-con-Dios and Godspeed -- Geekinator (aka Craig).
