It's your very weak CPU that's holding your system back.

Yeah maybe but I didn't have enough money to buy a new one :$

That APU is a huge bottleneck. 4gb of ram isn't help either

Would it be bether to buy a new CPU or another 4gb of RAM if I make enough money to invest in my PCU?

1. Shouldn't need to, but make sure all drivers are installed and the hardware is working properly.

2. What makes you think it is not doing so well? There's only 4GB of RAM, so that can be used up quickly depending on how much background programs and such you may have open at once. Fresh install would clear those out so you have a bare OS with maximum available memory.
