HD 4870 100% fan and red light problem!

Sep 28, 2015 6:04AM PDT

am having problem cause my fan is spinning and 100%, also have no post!

Also when i unplug my 2x6 pin connectors am not getting the two red lights at my graphic card.
D1602 (External power connector A) and
D1603 (External power connector B).

The thing is when i plug 2x6pin and start computer the graphic card blink 3 red lights at start as it should but the fan is spinning like crazy. And the same thing is happening when 2x6 are not plug in.

The GPU phase are ok and the memory too.

Can you guys give me any input on this one.
Is my Bios dead or maybe Shim Controller?

Odd to unplug power and turn power on.

That surely doesn't work. Try removing parts till it beeps. That's how I troubleshoot. A PSU, speaker, motherboard, CPU+HSF beeps for me. If not I am looking at the bad parts.

It's not about removing parts, cause it did all that!
Have like 10 mobos and graphic card and they are all working just fine!
The thing is about this one, it's just spinning like crazy and as far as i can see am getting like
1.8v on bios.......so could be its dead!

Maybe someone here is using this card and can tell something more about it!
