I need help with hardware

So before I start please don't grill me if I sound stupid, I have a general knowledge of computers but I still have a lot to learn which is why I'm here, here are my stats.

Tech Support Guy System Info Utility version 1.0.0.4
OS Version: Microsoft Windows 10 Pro, 64 bit
Processor: AMD Athlon(tm) II X2 250 Processor, AMD64 Family 16 Model 6 Stepping 3
Processor Count: 2
RAM: 1791 Mb
Graphics Card: ATI Radeon HD 4200, 256 Mb
Hard Drives: C: 110 GB (61 GB Free);
Motherboard: BIOSTAR Group, A785GE
Antivirus: Windows Defender, Enabled and Updated

I was wondering if this setup I have will play newer games like Fortnite and League of Legends. The only problem I know of that I need to fix is I need to get more RAM. But I was also wondering if I could put 2x4gb sticks of RAM in my computer, or is that too much. I appreciate anyone's help. And again please don't grill me if I sound stupid. xD

 

Max ram is 2x4 gig sticks

 

Thank you, if I put that RAM in my computer will it speed it up? My system runs very slow and can barely operate. I put windows 10 on it and it runs slightly faster now.

 

U have a low power processor
U have onboard graphics hd4200 ???
4 gigs of ram ..... windows 10 really shines with at least 8
If u want to game, a new more powerful computer is the way to go
Kinda wasting money trying to upgrade

 

Ok good deal, that’s the straight forward answer I was looking for. Thank you for the help.
