Issues appeared only in certain "houses," others worked fine, tested various devices.
I’m experiencing some serious issues across multiple setups. At each home, the PCs run poorly, games perform well in FPS but visuals are choppy with inconsistent frames and jerky mouse control. The power quality seems unstable—no grounding at my place, other houses worked fine after changes. I’ve tried adjusting BIOS settings and Windows configurations, disconnected all connections except one, tightened wiring, and even used aluminum foil on walls. Plugging in case fans worsens the lag. Software tweaks didn’t help; I’m considering more extensive fixes. If you need something, DC fans are the only solution I’ve tried so far.
I didn’t have the funds, but I checked the outlet voltage and it stayed steady for hours. My home is quite old—around 40 years or more—and I’m considering borrowing a generator to see if any issues come through the air or cables.
It looks like there could be a power problem. You might notice unusual drops in current. I don’t know the local market well, but I’ve seen some used UPS units on clearance sites priced at five dollars, bought twenty new batteries, and received a great UPS for a very low cost.
Definitely consider this upgrade—it will remove all the unusual microjitter that regular meters can't detect
It might be related to electrical issues, but have you attempted disabling Wi-Fi or wired connections on the machine during testing? It’s possible all devices are still active and, upon a cold start, they’re transmitting large amounts of telemetry and search results to Microsoft, overwhelming your upload capacity. Navigate to Settings, privacy, and disable every setting except basic. Switch collection data from "recommended" to the new default option. Try opening Task Manager, selecting the Performance tab, then Resource Monitor. In Disk section, click the bar labeled "read kbps" to filter the list. This could reveal significant background processes from a cold boot, showing which files Windows is currently handling. Check the Network tab in Resource Monitor for excessive non-user traffic and verify upload statistics—usually limited on home networks. This should help clarify whether network activity is contributing to the slowdown.
I also attempted to run without a network and turned off the NIC via BIOS. Privacy settings were kept at their lowest or off. I tried a metered network setup before, but mostly focused on network and CPU usage; disk activity was limited. Solid advice, thanks!
