Speeding up a slow PC deserve to be a challenge, particularly when managing older hardware that may be top top the cusp that needing an update or instead of anyway. Sometimes, a device simply demands a new OS download or driver update to perform substantially better. In various other cases, upgrade or wholesale replacement space necessary.

You are watching: How to diagnose a slow computer

This article is designed to help you troubleshoot a slow-moving machine. Specifically, the walks v the procedure of determining whether your trouble is more likely come be resulted in by software, hardware, or just the period of the machine.

Initial Questions

Whether you are doing this because that someone else or because that yourself, right here are a couple of “big picture” questions to consider:

Has the system’s performance adjusted recently? If the answer come this is “Yes,” go it adjust when you installed a particular application or OS update?Has the entire PC slowed down, or just specific applications? If the problem is isolated to one application or a particular group the apps, have those applications been freshly updated or modified?Does the device feel sluggish and slow to respond to feedback prefer typing? walk it have this difficulty in all cases, or just when specific programs room running? does it have actually the very same lag if booted in safe Mode?Does the system start to run slowly after a few minutes of work-related or gaming, or is it sluggish from boot?Is the system simply slow, or is it likewise unstable? If it crashes, is over there a particular application or application(s) that renders this happen reliably?

The answers come these concerns will aid you know where the difficulty is most likely to be. If the maker is smooth and also responsive in for sure Mode but lags badly as soon as booted come a common desktop, check and also see what applications instantly start once you boots up windows 10.

The answers to these questions are as crucial as the baseline specs that the system, particularly if you’re trying to save money.

How carry out I phone call If My pc Is “Just” Slow?

A computer that’s “just slow” shouldn’t have any other real difficulties apart native the absence of performance. Girlfriend should have a feeling for exactly how long it’ll take it to open a webpage or beginning a game, and you shouldn’t see any kind of unexplained variation in those times or certain instability when performing them. A slow-moving PC may thrash the hard drive if friend ask that to open up too many web browser tabs simultaneously, yet there must be a reasonable and predictable (to you) relationship in between how much work you space asking your pc to do and also how conveniently it can do it. A maker that’s “just” slow shouldn’t have problems with pop-ups or persistent trojan and also malware infections, and also it shouldn’t be unstable.

If you’re a gamer on an old gaming PC, said device should still operation the same gamings you purchase it come play ago then (with allowances for OS compatibility or driver issues). If you could run BioShock unlimited at 60fps on her current computer system in 2013 you should be capable of to run it today. If BioShock limitless (or any type of other old game or application) plays and also runs perfectly, however newer software doesn’t, you might be looking in ~ a situation where you need to upgrade together opposed to managing an underlying hardware or software application problem.

Any computer still using a magnetic HDD is walk to feel slower 보다 a pc equipped through a SATA or M.2-based SSD. Any kind of PC with less than 4GB of ram is walk to battle at least some of the time under also moderate workloads. 8GB should be considered a minimum because that any modern-day gaming. Dual-core CPUs without Hyper-Threading / SMT and also CPUs based on Intel’s Pentium, Celeron, or Atom product lines are more likely to “feel” slow, also if the device is well-configured. Systems based on old AMD CPUs from the Phenom II era or the Bulldozer/Piledriver product households do no offer an especially high performance.

A mechanism that was brand-new in 2013 and hasn’t been upgraded due to the fact that shouldn’t feel favor the latest-and-greatest in 2020 — however it shouldn’t it is in riddled with unexplained performance drops, either.

Tracking Down software application Problems

Performance troubles are much more likely to it is in software-related if they are linked with an underlying change to the OS or target application. If you’ve to be gaming v no problems but recently to buy your first new title in months, her GPU vehicle drivers may should be updated to play that appropriately. It’s never a poor idea to check the minimum specifications because that a brand-new title come make sure you accomplish them: If you’ve got a GTX 480 and the game recommends a GTX 770 as a minimum card, you may well have found the cause of her problem.

Similarly, if you have an older system and you space having issues related to a particular subsystem (networking, sound, video), it may be precious updating her chipset and also component drivers as well. The possibility of this resolving a difficulty is much higher if there’s an really identified worry with what you’re making use of already, but I’ve had reinstalls work out issues prior to from look at unrelated causes. It’s rare, however the chance isn’t zero.

Tools choose Task Manager have the right to sometimes be supplied to troubleshoot straightforward software difficulties with responsiveness and also performance. Repetitively high CPU intake may suggest a trouble with an application, especially if it’s a browser and also especially if killing the procedure improves device responsiveness. Some internet browser extensions have the right to cause greater CPU usage under details circumstances.


When you check Task Manager for CPU usage, you can likewise check the Startup tab. Make certain you recognize the applications that are loaded and running. You might not acknowledge every process detailed in the “Processes” tab, however look for suspiciously names or random, nonsense strings the text. In part cases, this might be a authorize you’ve to be infected by malware — and malware have the right to steal CPU and also GPU time for cryptocurrency mining and harm all at once perf.

Event Viewer may save on computer data concerned a performance concern or slowdown, yet honestly, it’s a crapshoot and interpreting event Viewer isn’t all that straightforward for the typical user. I’m not touching on that much here as a result.

If girlfriend are pertained to that old 3D drivers might be hanging roughly on her rig and also cluttering up its performance, tools like display screen Driver Uninstaller have the right to be offered to fully remove these traces. I usage DDU because that reviews when testing AMD and Nvidia cards. Booting into Safe Mode, running the tool, and also then booting earlier to desktop adds part steps contrasted with just installing a newer driver. But if you’re trying come troubleshoot performance issues, DDU is a good way to ensure you’ve cleansed her metaphorical palate. If you room having concerns with your sound map or network solution, it may be worth visiting your motherboard seller to watch if they’ve released updated motorists for these components, for example.


When every else fails, a complete Windows reinstallation will virtually always nuke any type of software-related problems and let you recognize if a hardware update is necessary. I try very tough not to take this step for apparent reasons — “Just reinstall Windows” is the sort of advice that expense US citizens millions when deployed as component of a plan to lie come people around the state of their software. Most people do no want to go to the problem of reinstalling Windows and also losing their existing data installations in the process. But if friend are encountering weird performance issues that you can’t lock down any type of other way, and you’ve tried the various other steps discussed here, it’s one method to deal with the problem.

There is an exemption to this. Sometimes, a Windows update is responsible for alters to user systems that cause high CPU intake or break Start menu functionality. Upgrading contents or an entire PC is no guard against these species of failures. In this instances, even a full Windows reinstall may not solve the issue.

We’ve discussed the software application side that the equation. Let’s talk around what i m sorry hardware problems are most most likely to slow a PC. I’ve tossed in a fair bit of discussion about what component fail looks choose in each instance to illustrate the difference in between the troubles that sap performance and also the troubles that revolve your computer into an high value paperweight.

Hardware Failure features (and which Ones ache Performance)

RAM: Failing RAM can make a game run much more slowly, yet only if the CPU is still having actually some luck pulling data out of it in ~ all. More commonly, applications just crash. The differentiating characteristic of ram failure is the there isn’t immediately a separating characteristic. If the failure has arisen at a high storage address, you may only watch the worry intermittently once you have actually a many programs loaded. The may happen mostly in games if gamings are what you generally run, however a ram failure will pop up almost everywhere given sufficient time. Applications favor MemTest86+ have the right to be supplied to check RAM. MemTest86+ is the just RAM test ns recommend — I’m no saying it’s the only great application available, but I’ve seen various other RAM testers insurance claim that memory was good when it in reality wasn’t. I’ve never seen MemTest86+ throw a false optimistic or false negative.

GPU: A failing GPU may display screen odd colors and also textures anytime you operation a 3D application, or duty perfectly for basic desktop work yet fail if asked come render a video clip or beat a 3D game. Utilizing a third-party utility prefer MSI Afterburner may enable you to fix the issue by one of two people lowering the GPU/RAM clock or boosting the chip’s voltage, but these fixes have tendency to be temporary. Games may crash at load or might run for short periods the time. The trouble may start in a certain title, yet it most likely won’t continue to be isolated. A failing GPU may also refuse to install its very own driver.

A GPU that runs perfectly for a long duration of time prior to you begin seeing errors or texture flickering may be overheating, yet may no be damaged yet. Dust the system and see if that enhances things. Plenty of games offer benchmark settings for trial and error GPUs, and also running this tests in a loop will certainly often develop a failure, despite it may take lot of loops through the check to watch it happen.

GPU failures typically will not slow-moving down the system, unless lowering the clocks you yourself (temporarily) fixes the problem.

CPUs: CPU failure are daunting to categorize due to the fact that CPUs almost never fail. If her CPU’s performance is dropping, chances are it’s a thermal worry — one of two people a mismounted heatsink or a thick buildup of dust. Make certain that her heatsink is properly an installed with an proper amount that TIM (thermal user interface material) between the CPU and its heatsink.

Power Supply: One method to uncover your computer PSU needs replacement is because that it come burst right into flames without warning. (Ask me just how I know!) A far less terrifying an approach is for your device to merely flip turn off or reboot during a gaming session or rendering run. In some cases, your motherboard may warn you that power distribution from the PSU to be disrupted. Power supply failures have the right to superficially resemble lamb failures, yet MemTest86+ won’t return errors and also the PSU won’t expedition while running basic desktop tasks unless it’s truly having issues. In these cases, your motherboard may likewise report the one or much more of the power rails is low. Bad PSUs regularly don’t cause slowdowns; they reason shutdowns.

Hard Drives: mechanically spinning drives might click quietly and also repeatedly once attempting to access details parts that the drive, or I/O performance may drop badly as soon as attempting to access data. Occasion Viewer may likewise log hardware fail if the OS can’t read data throughout the bus properly. SSDs will certainly not click (no relocating parts), but they may display the very same longer-than-expected access times or sharply diminished performance as the CPU make the efforts to read data native damaged components of the drive. In many cases, these species of failures will certainly kill the journey altogether fairly than leaving that limping follow me at a lower level the performance.

Low storage Space: not a “failure” as such, but it’s a hardware issue, no a software application one. Windows usually does not prefer to run without difficult drive space. The less complimentary space friend have, the much less the OS likes it. This deserve to lead come errors, application crashes, and cache thrashing, every one of which injury performance.

Heat: I’ve made decision to list “heat” as a typical characteristic that hardware instability and also lost perf, quite than break this the end by CPU and GPU. Dust is an amazing insulator. Fill in sufficient of it and fans won’t also spin. I’ve shed count the how many gamers and readers I’ve met who were afraid they essential to buy brand-new hardware, just to discover that dusting what lock owned restored the performance they were missing. Laptops have the right to be a tiny trickier come dust than PCs, yet if you have a desktop computer and room experiencing instability when gaming, pop the next of your instance off and see if things don’t improve. It’s no guarantee — however it’s no a hard thing to test, either.

A computer with problems in simply one game or a grasp of games may only need a driver update, especially if the titles are newer. A machine that never crashes during desktop computer or internet browser work yet slows down and crashes throughout gaming might need to be dusted. When I operation into world who are suffering computer crashes if gaming, one of my very first pieces the advice is to take the side panel off their computer. The growing popularity of laptops for gaming has actually made this solve a little less applicable 보다 it used to be, but you’d be amazed how plenty of “unstable” PCs become stable if friend just enhance airflow. Dusting is obviously the best method to do this, yet you can’t constantly take time native a raid instance or Fortnite video game to hunt under a deserve to of compressed air. Simply taking a side panel off is a quick means to test this theory.

Systems are less likely to crash outright from high temperatures 보다 they offered to be, however throttling can still play funny hell with video game performance. I always check thermals when I’m evaluating system behavior.

Of all the issues here, I’d speak dust, driver updates, and also low disk an are are the 3 most usual factors likely to reason slower-than-desired performance in the absence of hardware failure. Broken software deserve to absolutely cause all path of problems, but these cases tend come be particular and details to the user in concern (or the hardware in question) and are much harder to solve in a general-purpose overview like this.

What deserve to Be Done around It?

Alright, fine. You’ve run through the checklists and also you’ve figured out your pc is simply slow. Currently what?

Finding hardware love throughout coronavirus needs being ready to spend an ext money 보다 usual in some cases. If you want to buy a customer GPU because that gaming, it’s a poor time because that doing so. You deserve to expect to salary 1.5x MSRP or higher at the moment. This is far better than the 3x MSRP cards were selling for earlier this year, but it’s not a case anyone regards together good.

If you are attempting to upgrade your general-purpose PC, look at at two characteristics: RAM and storage. If you have actually an old machine stuck ~ above a spinning difficult drive, examine into whether it have the right to be upgraded come an SSD. Also some laptops have the right to be thusly equipped, though whether your device qualifies depends on its warehouse interface and also how user-accessible that is. If upgrading together a mechanism is out of the limit of this article, there room options.

The difference between a ram upgrade and an SSD upgrade for one older device is this: lamb will assist you if your difficulty is the you don’t have enough RAM. Make the efforts to run an application on 1GB of lamb if it demands at the very least 3GB to operation well will bring about drive paging and a many slowdowns v erratic overall performance. If you already have enough RAM, though, much more RAM won’t have to help. 4GB of lamb is quite small for a new an equipment these days, yet a 4GB an equipment should still be capable of running web apps, native processing, and other simple tasks there is no a problem.

A solid-state drive, if friend don’t have one, is not a replacement because that RAM. However if ram bottlenecks space not specifically your problem, a hard state journey will speed up everything else. In a details situation wherein a pc is short on RAM and also needs an ext for an applications you have to run, obtain the RAM. In a generic situation where you just want to speed up the everyday experience of making use of a PC and low lamb is not the problem, choose up an SSD. Even older SATA-only models have actually an bespeak of magnitude better latency than traditional spinning disks.
