So I've had my PC for probably around 5 years, and all this time, it's worked fine for me, save for a couple minor hiccups that have all but died out. Recently, however, I've been hitting a new issue - the random lag spikes mentioned in the title. I've noticed that it generally tends to happen in games as I go around a corner, through a door, or move too fast, but there are occasions where it just happens for no reason. In the best detail I know how to give, the whole screen locks up for maybe a second or 2, and then returns to the comfortable 45 to 60 fps I usually run at, and this only happens with certain games (i.e. Battlefield 1, Siege, Blade & Sorcery), and not in others (i.e. Dead By Daylight, H3VR). I originally thought it was a connectivity issue, and for the last week or so I've been messing with ethernet cables and routers, but my lack of success and notice of this issue recurring in some offline single player games, I'm not quite sure. I also have an integrated Intel video card along with the NVIDIA one, but I don't think the games are mistaking that as the one to use, as I reach but can't maintain good fps, and I've tried disabling it and forcing games to use the NVIDIA one, to no success as well. I'll list some PC specs below, but I don't really know what you all would need to know to be able to help, so if I miss something let me know .
