I just got a new computer (self build), with:
CPU AM2+ AMD Phenom II X4 940 6 MB
MB AM3 ASUS M4A785TD-V EVO / AMD 785G
RAM 4096 MB DDR3 PC3-10666 CORSAIR XMS3 DHX 1333 Mhz
PSU 520W CHILL INNOVATION CP-520A4M
VGA PCI-E 896 MB GEFORCE GTX 275 ASUS HTDI
HD some SATA2 drive, I don't remeber
I'm quite sure the motherboard has AMI BOIS.
But when I power up i get a 1 long - 2 short beep error. Even without RAM or video card. I can't find this code anywhere for AMI. For AWARD BIOS, where it means a video system error.
I've asked around, and someone said that his ASUS board gives this error, with no RAM.

Can anyone shed some light here?
