My laptop is old I mean really old. Let me add the specs. 2GB DDR3 RAM, Pentium dual-core processor (emerald lake I guess), 5400 rpm wd elements hard drive (I don't know but due to some reason it gets hot while I use). I am having trouble using chrome, vs code, atom etc but I want to upgrade please, tell me, will only 8 GB of DDR3 RAM do good or not? Any other suggestion will be highly appreciated.
