Bob, John, thank you very much for your advices.
This evening, after work, I went to a local PC shop
and bought a few cans of dust blower (compressed gas)
and cleaned M/B as well as memories.
Also, all memories and expansion cards were removed
and inserted back...
After the operation, the six beeps went away and
now I can see SRM...

I didn't try to load frimware as because the above
prescription worked...
Thanks for your suggestion, Michael and Marc.

Yours,
