Can't figure out the cause - screen flickering/lagging issues

I have a question regarding my power supply. I’m still running on some old circuit breakers, and I’ve noticed the indicator light is flickering. I just hopped on a call with a friend, and he mentioned his stays perfectly steady. Could anyone tell me if you experience this kind of flickering when you're dealing with older electrical setups? More importantly, I'm wondering if this could be impacting my hardware. My newer rigs are experiencing stuttering and lag—it feels like some sort of nasty microstuttering issue.

Which specific light are you referring to?

Since you mentioned earlier that you're running a UPS, we can probably rule out fluctuations in the main power line as the culprit here.

Look, it’s about the power supply and the circuit breakers. It either works or it doesn't.
If the voltage drops too low—even if it seems high enough when you first boot up—and then dips five minutes later or a breaker loses contact, the PC is going to shut down or reset. 100% certainty on that.
There is also the possibility that your motherboard is just low quality. Neither ASRock nor ASUS are top-tier.
I've dealt with faulty breakers plenty of times myself. Like I said, they either function or they fail; they don't flicker.
If you don't mind, try lowering the FSB in the BIOS by about 5%. It might help stabilize the entire chipset.

At the end of the day, if you're seeing the exact same behavior across six different setups, we aren't looking at a fluke; we're looking at an outside influence.

If this were a power delivery issue, you’d likely hear the power supply unit screaming for mercy. Personally, I’m not buying the electromagnetic interference theory just yet.

Now, pinpointing exactly which device is acting as the culprit? That’s the million-dollar question, and honestly, it's a tough nut to crack.

That said, @rowdycobra552, why don't you try taking the rig over to a friend's place again? But here's the twist: leave your current power supply behind and swap in theirs.

It shouldn't run properly if there's a fundamental issue, but if it suddenly starts behaving, then you've found your smoking gun in the power supply.

Also, if you have an old, reliable PC lying around, give that a shot. Shut down everything else in the house—unplug all the other appliances—and just boot up the computer. Then, every ten minutes or so, plug one device back in and see if that triggers the glitch.
