Black screen monitor crash, forced restart and need to manualy turn on the GPU.

Hi, i had this problem for a week. It started suddenly and maybe correlated with the last adrenalin update but im not sure. I can't know if its because my GPU is dying, if its a driver problem, or a windows uptade one...

Problem :

When i play a game my screen turn black and tell me "no signal", i Can still hear the sound for a while but can't do anything.

When i restart my computer i need to turn on my GPU manualy each time.

In the last 7 days i had maybe 40+ crash, and not a single gaming session untouched. It seems like it happens faster when i push all the graphics to the max and/or if i have multiples internet tabs opened in a navigator. When i lower the setting the crash take more time to happen.

I have seen multiple reddit thread describing a similar problem, and i tried a lot of different "fix" but none worked : clean windows reinstall, DDU, AMD cleanup, Adrenalin clock undervolt (max -50Mhz), Driver install only (multiple versions 25.9.2, 25.9.1, 26...), i reinstalled all the chipsets drivers, i updated my bios, checked my GPU cables, unmounted it and put it back properly... Honestly im out of solutions, and out of diagnostic.

If anyone could help me or have any advices i took them. Or if you have a similar problem please let me know what you have done to fix it or where you're at in your fixing journey.

Thanks
