I'm using a dell inspiron with core i3 7100U and has a 6GB ram. Can I replace my processor with an AMD A6 or an equivalent AMD processor. Will it affect the current motherboard ?
1. You cannot put an AMD CPU on an Intel motherboard.
2. Your current i3 7100
U is a BGA socket, soldered directly to the motherboard.
You can't change that even to a different Intel CPU.
