DH61WW Video error (no add-in graphics card installed)

Hi Team,

I am facing a problem with the DH61WW motherboard.

Below is the discription of my error:

On-off (1.0 second each) two times, then a 2.5-second pause (off), the entire pattern repeats (blink and pause) until the system is powered off.

Can you please provide any resolution for the above issue. Any help is greatly appreciated.

Many people suggested to reset bios, but can u please confirm how to resolve such kind of issues.

Thanks,
Vamshi Singam.
