Shouldn't this be able to Handle Minecraft/COD: BO2 Without laggin?

Graphics Card: AMD RADEON HD 6410D
Processor: AMD A4-3420 APU
Memory: 4GB
System-Type: 64bit.

How would I upgrade it so it doesn't lag? Like Get a new graphics card? Or a new Processor? Or more Memory? Please & Thank you.

Added (1). Dota 2 even Lags.

It shouldnt lag on minecraft since it doesn't use alot of resources
But this would most likely lag on Call of duty because its more intensive on graphics and you can't really upgrade anything in laptop so you would have to get a new laptop
You might be able to upgrade your ram but i'm not sure if that would help at all
