Thanks for your help. was kind of hoping that I was doing something stupid and/or it was an easy fix, but it is good to know that it was not me I guess.

Have tried 2 ps2 keyboards and 1 usb. could not get into BIOS. The 8pin 12cATX is connected. CPU heat sink came with thermal paste on it. no other power supply. think I am just going to have to return the MoBo and CPU

Correct!

removed dvd and hdd. Graphics card is onboard so can't remove. get the same single beep but now they is no BIOS splash screen just blank. removed RAM. and now it gives me the BIOS error code: 3 short beeps space 3 short beeps cont.

SYSTEM: GByte GA-F2A55-DS3 sFM2 MoBo AMD A6 5400K Black Edition CORSAIR CMX8GX3M1A1600C11 First powerup allfans turn on, keyboard lights flash on then go out leaving just the num lock light on. MoBo Beeps once. BIOS splash screen comes then after a couple of seconds the screen goes blank and that is it a blank screen for evermore. Can't access BIOS as keyboard not responsive. Tried: Different keyboard Clear CMOS reseated and then moved RAM Please Help!!!!!
