Dead 3070?

[Gibob]

Hi, 

i have a system with a rog strix b550f gaming, r7 5800x, msi rtx 3070 gaming x trio, 16GB 3600 cl 18 corsair vengeance and a corsair cv650w.

I built the computer back in 2020. Suddenly one of my two monitors stopped getting a signal from the gpu. Then after that it was both displays. To fix this i tried booting without the monitors plugged in and connecting them after, and it worked. But then the white gpu light on my mobo showed up. It still worked for a couple of days until now. It boots but when i get in to windows my fps drops super low before blue screening.
Is my gpu dying?

forgot to mention but i also tried the other pcie slot but without any results.

Can you get into safe mode?

Welcome to the forums!
First, reseat the GPU and power cables (both ends if it's modular). Then try different cables and if possible different ports on the GPU (unlikely to be the issue, but it's cheap and easy).
If possible, try a different PSU. Yours is a C tier and at >4 years old it might be failing.
You also mention crashes. Assuming they're BSODs, that's concerning. Is there a consistent stopcode? If they are more like PC shutting down, that's almost certainly a PSU problem.
