It wasn't purchased used (to my knowledge), and I have done a lot of uninstalling of programs that came with it, but that were unwanted. This computer was purchased, came straight out of the box, from Target.
However, I cannot open up Discord, nor a browser window while I'm doing it (which sometimes is necessary), and I struggle to open either when I'm not also playing a game. When I run World of Warcraft, or play a number of games (apps) from the Windows Store, it runs pretty smooth, and I get minimal performance issues. When I type into programs like Discord, my letters only appear about 1-2 seconds after I type them (letter by letter), or each word appears at a rate of 1 word per 1-2 seconds (my typing speed is about 118wpm). When a browser opens, it may take 5-20 secons for the page to even load (even a basic page like the Google/Firefox search bar), and I sometimes have to click it, watch the window fade out for a few seconds, then come back loaded.
Issue: I keep running into the same issues: when I try to run programs like Discord, Firefox, Chrome, or any of those other things, I find the computer to be lagging very badly.
