Macbook pro 15" no video e fan to max

[Eleways]

Hi there

I've 2 Macbook A1286 Late 2010, with motherboard 820-2915-b.

Both macbook had the same trouble, start, no video and after some seconds the fans start to run fast.

I've tried to exchange GPU AMD 216-0809000, one of this now work fine but the fans run very fast. No heating problem, just 49 degree.
The other one no video and the fan to max.

Anyone can help me on this?

Many Thanks

Luca

Start with the Bios yours has a dirty me region. or fake used GPU sold as new.

I guess you bought bad/remarked GPU. If you are not 99% sure the GPU you bought are good, then they are bad.

Hi

Thanks for your suggestion.

No Bios problem (replaced with a good one), and not GPU problem (2 different GPU repaced same problem).
