I've heard mixed advice about how long I should wait after turning off my PC before removing or replacing any components. Some people say I can start right away, while others warn that I might need to wait a week to avoid damaging anything. What's the real deal on this?

You're safe to work on your desktop PC almost immediately after powering it off and unplugging it. Just remember that parts like the PSU can hold a charge that can be dangerous, so don’t open it unless you know what you're doing.
From my experience building PCs for over 35 years, I've never waited at all. You can pretty much remove parts immediately after turning the computer off. As long as the power supply is off and unplugged, you're good to go!
So it's just a myth that you need to wait? That's interesting!
There's no real wait time needed. Just shut it down, unplug it, and hold the power button for a few seconds to discharge capacitors. You'll be ready to swap out parts right away! Just keep it safe—avoid touching any of the PSU components directly.
Honestly, just turning off the PC and unplugging it is sufficient. If you're swapping parts like a CPU cooler, it’s actually easier to do it while everything’s still a bit warm. Just don't rush if you're troubleshooting; take your time!
What about static electricity? How do I make sure I’m not zapping anything?
You can also help discharge any residual power by pressing the power button a few times after unplugging the PSU. Just make sure everything is off before you start tinkering with the components!
Is this different for laptops? They don’t really have PSUs, right?
