Strange problem with Gigabyte z77x-ud3h

[sudo_]

Out of nowhere my PC dropped dead. Now when I try to start it debug LED shows no code and m_bios and b_bios lights keeps flashing.

Any help would be appreciated.

Thank you for fast reply.
I've removed my AMD 7850 and one RAM stick still the problem persists.

Hello... have you read your manual PDF for your MB? Sounds like your Power supply is not working with your MB, if the above is not helping.

My PSU is corsair CX 500 it is 8 months old.
What else could be a problem?

Hello... Have you tried un-plugging it? looking at the Connections? inspecting the connector pins? or Cleaning them? And have you read your manual PDF?

I tried clearing CMOS and it seems to have worked but now the debug LED shows code 04 is it something to worry about?
And yes I have read the manual it does not have code 04 listed.
