GA MA790GPT-UD3H

i have a gigabyte ma790gpt-ud3h rev. 1 and 2x2gb of memory modules from corsair CMD4GX3M2A1600C8.
the processor is a Phenon II x4 955 black edition 3.2ghz

im not sure if the problem is the onboard video card or the memory.

aways when i turn on the computer for the first time of the day, the system doesn´t boot.

a small green retangle and a character "Ñ" appears on screen. nothing happens after that!
i have to press the reset button to system boot up normaly.

i´m using only onboard sideport with dvi conection. i tryed all possible configurations in the bios.
i set corretly voltage and clock of memory. i tryed to change memory slots and nothing...

anyone knows about that error?

  7. AGESA means AMD Generic Encapsulated Software Architecture', is a bootstrap protocol by which system devices on AMD64-architecture mainboards are initialized.

    The AGESA software in the BIOS of such mainboards is responsible for the initialization of the processor cores, memory, and the HyperTransport controller
