Question Is this okay to use ?

[Makazu]

Recently bought a used pc and
during shipping it wasnt package properly and ended up damaging some parts to the motherboard and the gpu

i cleaned it up with a white eraser. Wondering if its safe to use any help would be appreciated

Heres the motherboard too, is these 2 parts still safe to use? are they repairable?
