Hello,
Thank you for the link of "mcplslg123", it's very exciting, on my previous motherboard (with damage of water) i found and located the four resistors which are involved in the modification. As soon as i could, i will disassemble my laptop in order to swap these resistors.
With the software occct i tested my device, and never the temperature of the amd/ati chip was higher than 58°c. (but it was desactivated in the device manager).
in the forum "amd community" i read that sometimes this atikmpag bsod was a matter of ram ( it may depends of the brand...

Hello,
Thank you for your answers.
I will seriously study your propositions of hardware modification; but i haven't the boardview file of the motherboard to locate tle elements...if somebody could give me a link for that i will be very pleased. (i allready have the schematics).
Here is the caracteristics of the motherboard : hp g72-b52sf, motherboard : P/N :01013y000-600-g rc8f32004ah1, product number : xf110ea#abh.
Probably, i will reflash the sp55430 previous bios, because the modded one doesn't bring nothing usefull.
i will try to send you the photos of the motherboard...

Hello,
On the pc hp g72 b52sf w10 bios:sp55430 each time that i reboot after an update i have a bsod with "video tdr failure in atikmpag.sys" .That's a problem with the ati/amd chip because when i desactivate the amd graphics in device manager the pc can work on the intel graphics. But that's not a valid solution because each time i reboot i have the bsod.
I tried several drivers , even sp50704, to initialize this chip, but i have always the same error of bsod ,or error code 31. On my original bios sp55430 it was not possible to switch the Dgpu toward egpu because the advanced...
