I have a Acer Veriton x2631 Desktop. It is slowing down. I'll need to upgrade to Windows 10 from 7, which will slow it down even more. Can I upgrade RAM myself with limited knowledge? With the current processor, will upgrading RAM even increase the speed enough? I also want to do photo editing as well. Help. These are my computer specs. Thank you so much for having this place to ask. https://www.newegg.com/acer-veriton...iness-desktops-workstations/p/N82E16883103966
