RAM upgrade for 15-r036ds or new?

[Kristen9]

So I'll start by saying I know nothing about computers.. Literally nothing-so I'll apologize in advance if my questions are so dumb it hurts..  I have this computer-15-r036ds 4GB DDR3L SDRAM (1DIMM) Celeron N2920 Windows 8.1. -I bought this a few years ago to use Affinity Designer on and do basic computer-y things.  Long story short...my kids really have enjoyed using it.  As you can imagine-its as slow as can be.. Using Affinity is quite frustrating as it keeps freezing up/lagging every minute or 2.  For sanity reasons.. I'm wondering if upgrading it to 8GB RAM will help at all.. Or if its just not worth it?  I have rather limited resources.. And need to go the most cost effective.. Yet still effective route.  I have also been considering a tablet PC (8GB RAM i5 8th gen) and am wondering if that would be worth spending the money on.. Or if its not gonna be a whole lot better/faster/smoother running.. Especially Affinity.  Thank you for any help or advice you can give..

Welcome to the HP Support Community  @Kristen9 

Adding more memory can help but try this first:

First thing would be to do a Disk Cleanup.

 

Check everything except Delivery Optimization Files

Then do a Disk Defrag. “OPTIMIZE”

 

Then go to Advanced System Settings.

 

In the Performance box click on SETTINGS.

 

Click on Adjust for Best Performance.

 

Click on APPLY. 

Then reboot.
