Possible EMI issues

[pleasehelp]

For around the past 2 and a half years, I've been dealing with the strangest PC issues that have been driving me insane. Before this, I had the PC for a year and a half with no problems (aside from some like microstutters, but those were fixed with a driver update or a change to some settings), but one day it just felt...off. I've seen this a lot on these forums, but the best way to describe it was a sluggish and heavy feeling instead of a quick, precise, and light one like it should be. At first I thought it was something wrong with the game I was playing, since it would happen very infrequently and seemingly only affect my controller. Soon after this started, I built a new PC - not to fix the issue, since I still thought it was a problem with the game, just to improve performance. After this, I started getting many more issues (these would later get fixed, but I'm listing them here on the slight chance that they could be related). Games would randomly freeze, I would have sudden lag spikes, my entire PC would crash when playing certain games (with everything becoming very pixelated and vibrant before most crashes), constant game crashes that made them unplayable, and random days where my controller sensitivity in games would still feel extremely off. All of these except for the last one were eventually fixed with a bios update. I still thought it was a problem with the game, since the days that my controller felt off were still relatively infrequent. At this time, I was living in an apartment, but a few months later I moved into newly built house - and this is where a whole host of new issues cropped up. Not only was I still having the sluggish and heavy mouse/controller issue, but I was also getting extremely high ping spikes (300-1,000) which later vanished but were replaced by packet loss spikes (100 packet loss, freezing my game for 2-3 seconds. This would also affect the entire house, not just my PC). These ended up going away later without me knowing what actually fixed it, but the sluggish mouse/controller issue still persisted and got progressively worse/more frequent. After coming back from traveling one time - before which I completely shut down the power to my PC - it felt worse than ever, with my mouse and keyboard having noticeably more input lag. Now, my controller and mouse both consistently feel sluggish, heavy, and slightly inaccurate; both of them, along with my keyboard, also feel like they have significant input lag. As the sluggish sensitivity issues have progressed, the visuals of games have also seemed to degrade noticeably. Sometimes they'll be sharp and smooth, and other times they'll look slightly more pixelated, less detailed, and not smooth whatsoever even with 240+ FPS. The strange thing is that past around 4:30 AM, games will sometimes feel much smoother and more responsive. Possibly unrelated, but I also had a random BSOD a while ago (that I never discovered the cause of), and my PC tripped the circuit breaker once. Any help would be greatly appreciated, gaming has become incredibly frustrating because it feels like my performance is tied to whether or not my game will feel playable for the day.

I dont know what it is either brother, had it since 2018. These settings into powershell i got from another thread here helps with some of the internet desync, maybe worth a try 'Set-NetOffloadGlobalSetting -ReceiveSegmentCoalescing Disabled
Set-NetOffloadGlobalSetting -PacketCoalescingFilter Disabled'
