|If you have a weak CPU, weak video card or not enough RAM, your system may very well be a poor for gaming, but none of that has anything to do with internet speed. You do understand what ping is, right? You tell me....where does the RAM come into play as far as ping is concerned?|

Who said that software was oh-so good? You need to run a cleaner such as CCleaner-Slim, an Anti-Malware program such as MalwareByte's Anti-Malware, & a decent anti-virus scanner. And you need to look at the startup list by running MSCONFIG or using CCleaner's Tools > Startup.
