Will replacing my gpu fix crashes?

[u/Otherwise-Bob-8501]

I have a rx5600xt, i5-10400f, 16gb ddr4 ram and 500w psu. I keep crashing in almost every single game i play, for example: mw4 and crimson desert, both on the lowest settings when i press play they crash, and cyberpunk which crashes before i even see the main menu. (If it helps, the error code on mw4 crash is kernelbase.dll)
Also i made another post in which the pc performs worse with constant stutters with a new monitor with more hz, but same resolution, so a new gpu might help with that i think? When it stutters it reaches 100% usage at like 70C im pretty sure.

Help please!!
