When most people think of IT, they think of the line, “Have you tried turning it off and on again?” And there’s a reason this cliché is so well known…. Sometimes, it actually works.
Everyone knows the advice. Almost nobody knows why it actually works, or how to tell when it’s the right move versus a waste of your afternoon. So we thought we’d take IT’s oldest cliché completely seriously, and explain the method behind the madness.
Maybe you’re sitting with a frozen screen, a printer that won’t print, or a laptop that’s crawled to a halt. You might quietly assume that admitting “I haven’t tried restarting it yet” makes you look like you don’t know what you’re doing. So you either sit there hoping it fixes itself, or call us and brace for the engineer to say, gently, “did you try turning it off and on again?”
Here’s the thing worth knowing: this advice isn’t a brush-off. It’s not IT support being lazy or trying to make you feel small. A restart genuinely does fix a specific, common category of fault. And once you know what that category actually is, you’ll know when it’s the right move and when it’s a waste of your afternoon. That’s really what this comes down to. It’s not “try restarting everything,” but helping you to understand why it works, so you can tell the difference between a glitch and a proper problem.
Why Reboots Work
Every device you use (whether it’s a laptop, a router, a printer, even a meeting room TV) is running software that holds things in memory while it works. It could be open connections, half-finished processes, cached login details, or bits of temporary data it meant to clear up and didn’t. Over time, the memory gets cluttered. Processes get stuck waiting on each other. A setting gets applied but never actually takes effect until the software reloads from scratch.
A restart clears all of it out in one go. It’s less “magic reset button” and more “closing every tab you’ve had open for three weeks and starting again.” Nothing wrong with the browser; it just had too much sitting in memory to work properly.
With that in mind, here’s how it plays out across the things most likely to go wrong in an office, so you know exactly when to call IT support, and when not to.
Wi-Fi and your router
This is the one most of us already do without thinking. When the router stops working, you unplug it, count to ten, plug it back in. It works more often than almost anything else on this list, and there’s a good reason. Routers are small computers, and like any computer, their memory can get clogged and their processes can get stuck. BT’s own advice to broadband customers facing connection problems is to turn the hub off at the wall, wait a few minutes, and turn it back on. It’s the first suggested step, not a last resort.
Restarting also matters for a less obvious reason: some router firmware updates (the software that keeps it secure and running properly) won’t actually apply until the device restarts. If you never switch it off, you might be running weeks-old firmware without realising.
Your computer itself
Windows updates are a classic culprit here. Microsoft frequently downloads updates in the background and waits for a restart to actually install the updates. So a computer that’s been left on for two or three weeks straight might be sitting there with security patches downloaded but not applied. The National Cyber Security Centre flags this specifically in its guidance to organisations. Some updates simply won’t take effect without a manual restart. So a device that hasn’t been restarted in a while may be behind on patches it needs. That’s not just a performance point, it’s a security one. It’s also a decent reason to restart your machine at the end of the week even if nothing feels wrong.
Beyond updates, a slow or unresponsive PC is very often just memory that’s filled up with background processes that never properly closed. Restarting clears the slate.
The printer that’s gone offline
Printers cause a disproportionate amount of quiet office rage, mostly because “offline” doesn’t mean broken. It usually means your printer, your computer and your router have each lost track of what the other two are doing. They each hold a stale picture of the network, and none of them realise it until something forces a fresh handshake.
The fix that actually works is restarting them in the right order: printer first, then router, then you should reconnect the printer once the router’s back up. And finally, your computer. It looks fussy, but it’s the difference between a genuine fix and the same “offline” message reappearing an hour later. Manufacturer support pages back this up as their standard first step before anything more involved.
Outlook, Teams and OneDrive not syncing
This is the one we’re =often most reluctant to try. After all, it feels like it should be a “proper” fix rather than a restart. But Microsoft 365 apps lean heavily on cached login tokens and locally stored data to sync quickly. That cache can get out of step with what’s actually on the server. A restart forces a clean re-authentication and a fresh sync. This resolves a surprising number of “my calendar’s out of date” or “Teams won’t sign me in” tickets before anyone’s had to touch a single setting.
It’s usually faster than the alternative most people reach for instead, which is uninstalling and reinstalling the whole thing.
Phones, and the office kit nobody thinks to restart
Most people already restart their phone occasionally without needing to be told; background apps leak memory and radios (Wi-Fi, Bluetooth) get stuck in much the same way a laptop does. What people don’t think to restart is the meeting room screen, the conference phone, or the smart TV in reception.
They run on the same kind of software as everything else on this list, holding onto memory and cached connections, but because they don’t look like computers, nobody treats them like one. If the boardroom display is being temperamental before a client call, it’s worth the thirty seconds.
When Restarting Won’t Fix It
This is the part that actually matters most, because it’s where “turn it off and on again” stops being good advice and starts being a way of avoiding the real problem.
A restart is a fix for a temporary state. Maybe that’s memory that’s built up, an update that’s waiting to apply, a connection that’s gone stale. It is not a fix for something that’s actually broken, and there are a few signs worth knowing, so you are clear about when to call IT support:
- There’s an error code or message. If something specific flashed up before you closed it, that detail is worth writing down before you restart; it’s often the one clue that tells an engineer exactly what’s wrong.
- You’re on the third restart this week. One restart clearing a genuine glitch is normal. Restarting the same machine or printer every couple of days is a pattern, not a coincidence.
- There are physical warning signs. A device that’s hot to the touch, making noise it shouldn’t, or showing error lights that persist after a restart is telling you something hardware-related, not software-related.
A Quick Self-Test Before You Restart
Next time something’s playing up, ask yourself three questions:
- Has this exact thing happened before recently?
- Did I see an error message, and did I note down what it said?
- Is this the same device I’ve already restarted once or twice this week?
If the answer to any of those is yes, try restarting. But it’s also worth flagging to whoever looks after your IT, because a pattern is exactly the kind of thing that’s cheap to fix now and expensive to ignore. And that’s when to contact IT support.
We can help!
None of this is about making you feel silly for restarting things; it’s the opposite. It’s a genuinely useful fix, and you shouldn’t feel embarrassed reaching for it. What’s worth paying attention to is the pattern underneath it: if you’re restarting the same device more than once a month, that’s not really a “you” problem. It’s a sign something’s worth a proper look.
That’s exactly the kind of thing we cover in our free Partnership Review Call. It’s an honest conversation about what’s actually going on with your systems, what’s a one-off glitch, and whether Tristar Tech Solutions is the right fit for your needs.

Frequently Asked Questions
Is it bad to restart my computer every day? No; if anything, it helps. It clears memory, lets pending updates apply, and takes a few seconds out of your morning routine. The only downside is a short wait while it boots back up.
Why does my printer keep going offline? Usually because the printer, your computer and the router have each lost track of the others on the network. A restart in the right order (printer, then router, then computer) fixes the immediate issue. If it keeps happening, the printer may need a fixed (static) network address so it stops losing its place.
Should I restart my router regularly, or only when there’s a problem? Both are reasonable. Restarting only when there’s an issue is fine for most homes and small offices. If you’re on a business connection with several people relying on it, an occasional scheduled restart (overnight or at a weekend) means firmware updates get applied without anyone noticing the downtime.
How do I know if it’s a router problem or my broadband provider’s? If restarting the router doesn’t help and other devices on the same connection are also struggling, it’s worth checking your provider’s service status page before doing anything else; there may be a known fault in your area that no amount of restarting will fix.
