Hi, I’ve bought new Dell laptop recently and it was lagging so much that it irritates me now.

It come with i5-7200U@2.5GHz, RAM 4GB (upgradable to 16GB I think(?)), HDD 1TB, Intel HD Graphics 620.

And the model is Dell Inspiron 15 5000-5567 and I wonder is it because I recently installed Dota 2 on it or what?

And I want to make it as good as a gaming laptop, which part of this that should I upgrade?
