You can not change the graphics chip. It is what it is.
To "compensate" for low graphics memory they have the bios reserve ram for graphics handling.

Setting it to the highest amount possible is not always working the best.
Laptops where/are not ment to play games on.
To prevent it from getting to warm, make sure air can freely flow underneath it.
There also laptop coolers available in (online)stores.

Do not run anything in the background that isn't really needed.
Most of those things are loaded when you boot Windows.
We can help you have a look at those things if you want.
