-You might have to tweak the game settings to make sure to optimize your pc. Also, checking your network connection may help and resolve the issue. I understand that you've already tried multiple solutions. I took a little look at your pc, and the pc only has Intel HD Graphics. While the minimum is Intel HD 3000. I hope this adds a clearer understanding to your issue in that you may not be able to run the game properly.
