If you don't already have a case speaker hooked up to the board, you might want to connect one since there isn't an on board speaker and you will not hear error beeps otherwise.

Also, if you have another non-phenom AM2 processor handy you should really update the BIOS to latest release. Many late model Phenoms will not work on motherboards that have earlier BIOS releases and you will not be able to post. You should then choose "Set Optimized Defaults" and save the bios without any changes then shut down (not reset). When you power on again it should post and you should be able to get into the BIOS.

A third thing you can try (after you get a case speaker hooked up) is using a cheap pair of ddr2-6400 RAM to get the board to post so you can get into BIOS and change the voltage to the correct settings for your RAM if it requires a higher voltage than the bios expects.

Hi,
What you hear are bios beeps. They signal you that something is wrong. These beep's vary by the manufacturer of the bios chip that you have.

You can find out what bios you have by looking at your manual. The common cause for one long and two short beeps is a video problem.

Either the video chip on your mobo is shot, or your video card needs attention.

3 beeps usually means that either the chipset or the processor is dead. Nothing you can do, take it to a repair shop.
