Yeah general computing shouldn’t be an issue for you. Is this a fresh install of windows? That can do wonders for problems like this, if it hasn’t been done in a while. Otherwise, ssd issue perhaps, you can use crystaldiskinfo to check drive health. Or, a temperature problem somewhere, are you monitoring temperature? I use hwmonitor. There’s also hwinfo which is what most people would recommend.
Office work? Yes. Gaming? eh… Perhaps some older games, or newer games at ungodly low resolutions. If gaming is important to you, you really want a dedicated gpu.
