Ringedge no siginal

[Mr.Seo]

Dear supporters,
Suddenely, my initial D8 is no siginal. I exchange the ram and graphic card with working one but still no siginal. I guess it is the board problem. Anyone knows this problem ? Let's hear your guys opinion.

What happens when you turn on the ringedge.

Do fans spin?

Reset the bios and change CMOS battery (look in VT4 manual for procedure).

Thank you for your advise ! I will try to change the battery. The fan is o.k. Everything is o.k but no siginal.
