Separate area for niche lag issues including unexpected causes and/or electromagnetic interference (ECC = retransmits = lag). Interference (EMI, EMF) of all kinds (wired, wireless, external, internal, environment, bad component) can cause error-correction latencies like a bad modem connection.

NEW PC and MOUSE and ONLY using the PC late at night

Post by jterri » 06 Jun 2026, 22:31

Hello everyone. I have been doing a bit of thinking, and I THINK i may have come up with SOME sort of fix for this issue. I don’t know if this will work 100% but it’s worth a try.

What if you buy a new PSU, Motherboard, CPU AND a new mouse and then ONLY use the new equipment late at night… between 10PM, 11PM or 12 midnight all the way until like 5AM. AS SOON as the clock hits 5AM then you shut your PC down completely and not run ANY power on the PC for the entire day until the clock its 10PM-12AM again. Do you think this would fix the dirty electricity issue? Or at least to an extent?

I say this because i’ve heard a lot of people talking about how their PC and mouse feels trash during the day and only gets better at night, though this doesn’t happen to everyone… i also did some testing with a greenwave EMI meter, and during the day i get about 1400-1500mv of electrical noise while at night i get 100-200mv of noise. Do you think this weird issue could be fixed by getting a new PC and mouse or replacing everything that COULD affect the mouse including the mouse itself and then only using the PC and mouse late at night?

Maybe, who knows. Also those EMI meters values often don't correlate with symptoms, so it's not like your ultimate detector. It might be like that by accident in some cases, for instance if source of your problems also emits some interference this device can detect.
Ryzen 7950X3D / MSI GeForce RTX 4090 Gaming X Trio / ASUS TUF GAMING X670E-PLUS / 2x16GB DDR5@6000 G.Skill Trident Z5 RGB / Dell Alienware AW3225QF / Logitech G PRO X2 SUPERSTRIKE / SkyPAD Glass 3.0 / Wooting 60HE / DT 700 PRO X || EMI Input lag issue survivor (source removed) 8-)

Interesting. I watched some youtube videos of people using this Emi meter and most of them were getting between 100-400mv of noise. I then looked up people on this forum who have used this meter and found that most people who used the device on this forum were getting between 500-1000+ mv of noise. Mostly 1000+ mv of noise. What are your thoughts on that? Most houses have clean electricity but there are those FEW houses with electricity issues, so what do you think?
