If you think the power supply is the culprit—a solid UPS would probably sort that out for you.
I'm actually calling in from Maui 😁

but I'll be heading into Los Angeles at the end of the month—so just shoot me a DM with your number and I'll give you a shout.

So, are you saying this exact issue has been haunting you for years, even when swapping out different parts?
Hmm...

Do you have any massive power draws in your house? Things like central AC units, large refrigerators, or deep freezers?
I mean, we all have those basics, obviously—but I’m wondering if there’s anything else running on that circuit.

Even though it might be a separate issue, phase interference can kick in if your PC is plugged into one circuit while your monitor is on another. It’s a huge deal with sensitive setups—like at a major convention center where you have multiple projectors running in parallel—or with high-end audio gear.
Then again... in that scenario, you’d likely see screen flickering rather than the actual system stuttering during a game.
Honestly, I'd love to get my hands on your rig just to run some tests myself.😁

The power supply isn't actually the issue here—if the voltage were truly too low, the whole system would just shut down. That’s exactly why you have a PSU in the first place; its job is to regulate and stabilize everything.

Hmm. Let me know about your RAM setup—are we looking at a single 8GB stick, or maybe 2x 4GB?
If it's 2x 4GB, was that bought as a matched kit, or did you add them later?
Same question applies if it's 4x 2GB.

So, when you say they aren't working in "windowed mode"—are you saying they just force themselves into full screen, making it impossible to drag them over to another monitor?

Personally, I’m always multitasking—I'll have a movie running in full screen on one display while keeping an eye on a torrent download on the other, or even something like
running World of Warcraft on one screen while browsing the web on the second...

I'm not quite following what the specific issue is here.
Just try hitting the Windows key + P on Windows 7 or Windows 8, then select whichever option you need.

If you’ve already cycled through different operating systems, then we can probably rule out driver issues.
If the system isn't crashing entirely—which is usually the tell-tale sign of a faulty RAM stick—then we're looking at something else.
Personally, I'd suspect some kind of background process is filtering traffic or running scans, causing that laggy delay.
What kind of antivirus software are you running?
Though, honestly, even that doesn't quite track if you've seen the exact same behavior on Linux. In that case, I’d lean toward overheating—either the CPU or more likely the GPU—though typically the CPU and motherboard would just trigger a hard reboot or shut down once things get too hot.
