Speeding up a slow PC deserve to be a challenge, an especially when dealing with older hardware that might be on the cusp of needing an update or instead of anyway. Sometimes, a device simply demands a fresh OS download or driver update to perform considerably better. In various other cases, update or everyone replacement space necessary.

You are watching: How to fix a slow pc & speed up performance

This post is draft to assist you troubleshoot a slow machine. Specifically, it walks with the procedure of determining even if it is your trouble is an ext 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 for yourself, here are a few “big picture” concerns to consider:

Has the system’s performance changed recently? If the answer come this is “Yes,” walk it readjust when you set up a details application or OS update?Has the entire PC slowed down, or just particular applications? If the difficulty is isolated to one app or a particular group the apps, have those applications been freshly updated or modified?Does the an equipment feel sluggish and also slow to respond to feedback favor typing? walk it have this trouble in every cases, or just when details programs room running? go it have the same lag if booted in for sure Mode?Does the system start to run slowly after a few minutes of work or gaming, or is it sluggish from boot?Is the system just slow, or is it likewise unstable? If it crashes, is over there a details application or application(s) that makes this happen reliably?

The answers to these questions will assist you recognize where the difficulty is most likely to be. If the machine is smooth and responsive in for sure Mode yet lags badly when booted come a typical desktop, check and see what applications automatically start when you boots up windows 10.

The answers to these concerns are as necessary as the baseline specs the the system, specifically if you’re trying to conserve money.

How execute I call If My pc Is “Just” Slow?

A pc that’s “just slow” shouldn’t have any type of other real difficulties apart indigenous the lack of performance. You should have a feeling for exactly how long it’ll take it to open up a webpage or launch a game, and also you shouldn’t see any type of unexplained variation in those times or details instability as soon as performing them. A slow-moving PC might thrash the hard drive if you ask it to open up too many web browser tabs simultaneously, yet there have to be a reasonable and also predictable (to you) relationship in between how lot work you space asking your computer to do and also how easily it deserve to do it. A an equipment that’s “just” slow-moving shouldn’t have difficulties with pop-ups or persistent trojan and malware infections, and also it shouldn’t be unstable.

If you’re a gamer on one old gaming PC, said device should still operation the same games you to buy it to play earlier then (with allowances because that OS compatibility or driver issues). If you might run BioShock boundless at 60fps on her current computer in 2013 you need to be qualified of running it today. If BioShock boundless (or any kind of other old video game or application) plays and runs perfectly, yet newer software application doesn’t, you might be looking at a case where you need to upgrade as opposed to dealing with an underlying hardware or software program problem.

Any pc still making use of a magnetic HDD is going to feeling slower 보다 a pc equipped with a SATA or M.2-based SSD. Any kind of PC with less than 4GB of ram is going to battle at the very least some of the moment under even moderate workloads. 8GB have to be considered a minimum because that any modern gaming. Dual-core CPUs without Hyper-Threading / SMT and CPUs based upon Intel’s Pentium, Celeron, or Atom product currently are more likely come “feel” slow, also if the system is well-configured. Systems based upon old AMD CPUs from the Phenom II era or the Bulldozer/Piledriver product households do not offer an especially high performance.

A device that to be brand-new in 2013 and hasn’t to be upgraded because shouldn’t feel favor the latest-and-greatest in 2020 — however it shouldn’t it is in riddled through unexplained power drops, either.

Tracking Down software Problems

Performance problems are much more likely to it is in software-related if lock are connected with an underlying readjust to the OS or target application. If you’ve to be gaming with no problems yet recently to buy your an initial new location in months, your GPU vehicle drivers may must be updated to play the appropriately. It’s never ever a negative idea to inspect the minimum specifications for a brand-new title come make sure you satisfy them: If you’ve acquired a GTX 480 and also the game recommends a GTX 770 as a minimum card, you might well have discovered the cause of your problem.

Similarly, if you have actually an larger system and also you space having problems related come a details subsystem (networking, sound, video), it might be worth updating your chipset and also component vehicle drivers as well. The chance of this resolving a trouble is much higher if there’s an really identified issue with what you’re making use of already, but I’ve had actually reinstalls settle issues before from seemingly unrelated causes. It’s rare, however the chance isn’t zero.

Tools like Task Manager can sometimes be used to troubleshoot simple software problems with responsiveness and performance. Consistently high CPU intake may indicate a trouble with an application, especially if it’s a browser and especially if death the process improves mechanism responsiveness. Some browser extensions deserve to cause greater CPU consumption under particular circumstances.


When you inspect Task Manager because that CPU usage, you can also check the Startup tab. Make sure you acknowledge the applications that are loaded and running. You might not recognize every process listed in the “Processes” tab, but look for suspicious names or random, nonsense strings of text. In part cases, this may be a authorize you’ve been infected by malware — and also malware have the right to steal CPU and also GPU time because that cryptocurrency mining and also harm as whole perf.

Event Viewer may save on computer data concerned a performance problem or slowdown, however honestly, it’s a crapshoot and also interpreting occasion Viewer isn’t all that basic for the typical user. I’m not emotional on it much here as a result.

If you are came to that old 3D drivers can be hanging roughly on your rig and cluttering increase its performance, devices like display screen Driver Uninstaller deserve to be supplied to fully remove this traces. I use DDU for reviews when trial and error AMD and also Nvidia cards. Booting into Safe Mode, to run the tool, and also then booting earlier to desktop computer adds some steps compared with simply installing a more recent driver. Yet if you’re trying to troubleshoot performance issues, DDU is a great way to ensure you’ve cleansed her metaphorical palate. If you are having issues with your sound map or network solution, it may be worth visiting her motherboard merchant to view if they’ve released updated vehicle drivers for this components, for example.


When every else fails, a complete Windows reinstallation will practically always nuke any software-related problems and let you recognize if a hardware upgrade is necessary. I shot very tough not to take it this step for apparent reasons — “Just reinstall Windows” is the kind of advice that price US citizens millions when deployed as part of a plan to lie to people about the state of your software. Most human being do no want to go to the hassle of reinstalling Windows and losing their present data installations in the process. Yet if girlfriend are facing weird performance problems that girlfriend can’t lock down any kind of other way, and also you’ve make the efforts the other steps debated here, it’s one method to resolve the problem.

There is an exemption to this. Sometimes, a Windows update is responsible for alters to user equipment that cause high CPU consumption or break Start food selection functionality. Upgrading components or whole PC is no guard against these species of failures. In this instances, even a full Windows reinstall may not resolve the issue.

We’ve disputed the software side the the equation. Let’s talk about what i m sorry hardware issues are most most likely to sluggish a PC. I’ve tossed in a fair little of discussion around what component failure looks favor in each instance to illustrate the difference between the problems that sap performance and also the problems that rotate your computer into an expensive paperweight.

Hardware Failure qualities (and which Ones pains Performance)

RAM: Failing RAM deserve to make a game run an ext slowly, yet only if the CPU is still having actually some happy pulling data the end of it at all. More commonly, applications just crash. The separating characteristic of ram failure is that there isn’t immediately a separating characteristic. If the failure has emerged at a high memory address, you might only check out the issue intermittently as soon as you have actually a lot of programs loaded. That may take place mostly in gamings if gamings are what you generally run, yet a lamb failure will certainly pop up almost everywhere given enough time. Applications prefer MemTest86+ have the right to be supplied to test RAM. MemTest86+ is the just RAM test ns recommend — I’m not saying it’s the only great application available, yet I’ve seen other RAM testers case that memory was an excellent when it actually wasn’t. I’ve never seen MemTest86+ throw a false positive or false negative.

GPU: A failing GPU may screen odd colors and textures whenever you operation a 3D application, or role perfectly for basic desktop work however fail if asked come render a video or beat a 3D game. Making use of a third-party utility favor MSI Afterburner may allow you to fix the problem by one of two people lowering the GPU/RAM clock or boosting the chip’s voltage, however these fixes tend to it is in temporary. Games may crash at load or might run for quick periods of time. The trouble may start in a certain title, yet it most likely won’t remain isolated. A failing GPU may additionally refuse to download its own driver.

A GPU that runs perfectly because that a long period of time prior to you begin seeing errors or texture flickering may be overheating, however may no be damaged yet. Dust the system and see if that enhances things. Numerous games market benchmark settings for experimentation GPUs, and also running these tests in a loop will often create a failure, despite it may take multiple loops with the check to see it happen.

GPU failures typically will not sluggish down the system, uneven lowering the clocks you yourself (temporarily) fixes the problem.

CPUs: CPU failure are daunting to categorize since CPUs almost never fail. If your CPU’s performance is dropping, opportunities are it’s a thermal worry — either a mismounted heatsink or a thick buildup of dust. Make certain that your heatsink is properly placed with an appropriate amount that TIM (thermal interface material) between the CPU and also its heatsink.

Power Supply: One way to find your pc PSU requirements replacement is because that it to burst right into flames there is no warning. (Ask me just how I know!) A much less terrifying technique is for your maker to simply flip turn off or reboot during a gaming session or calculation run. In part cases, her motherboard might warn you that power distribution from the PSU was disrupted. Strength supply failures can superficially resemble ram failures, but MemTest86+ won’t return errors and also the PSU won’t expedition while to run basic desktop computer tasks uneven it’s truly having issues. In these cases, your motherboard may also report that one or an ext of the power rails is low. Negative PSUs often don’t reason slowdowns; they reason shutdowns.

Hard Drives: mechanical spinning drives might click quietly and also repeatedly once attempting to access details parts that the drive, or I/O performance might drop badly when attempting to access data. Event Viewer may likewise log hardware fail if the OS can’t check out data across the bus properly. SSDs will certainly not click (no relocating parts), but they may screen the exact same longer-than-expected access times or sharply lessened performance together the CPU do the efforts to check out data from damaged parts of the drive. In numerous cases, these types of failures will certainly kill the journey altogether fairly than leaving it limping along at a lower level of performance.

Low storage Space: not a “failure” together such, but it’s a hardware issue, no a software application one. Windows generally does not prefer to run without tough drive space. The less cost-free space you have, the much less the OS likes it. This can lead come errors, applications crashes, and also cache thrashing, every one of which damage performance.

Heat: I’ve chose to list “heat” as a common characteristic of hardware instability and also lost perf, quite than breaking this out by CPU and GPU. Dust is an impressive insulator. Fill in sufficient of it and also fans won’t also spin. I’ve lost count that how plenty of gamers and readers I’ve met that were fear they needed to buy new hardware, just to uncover that dusting what castle owned restored the performance they to be missing. Laptops deserve to be a small trickier to dust 보다 PCs, however if you have a desktop and are experiencing instability while gaming, popular music the next of your instance off and see if points don’t improve. It’s no guarantee — yet it’s not a hard thing to test, either.

A pc with worries in just one game or a handful of gamings may only require a driver update, specifically if the titles are newer. A machine that never ever crashes during desktop or web browser work yet slows down and also crashes during gaming might need to it is in dusted. Once I operation into civilization who are suffering pc crashes while gaming, one of my first pieces of advice is to take the next panel off your computer. The growing popularity of laptops for gaming has actually made this solve a tiny less applicable than it provided to be, yet you’d be amazed how countless “unstable” PCs become stable if you just boost airflow. Dusting is clearly the best method to execute this, but you can’t constantly take time indigenous a raid instance or Fortnite video game to hunt under a can of compressed air. Simply taking a next panel turn off is a quick method to test this theory.

Systems are less likely come crash outright indigenous high temperatures than they offered to be, however throttling can still play funny hell with video game performance. I constantly check thermals when I’m analyzing system behavior.

Of every the issues here, I’d speak dust, driver updates, and also low disk space are the three most common factors likely to cause slower-than-desired power in the absence of hardware failure. Broken software deserve to absolutely reason all manner of problems, however these instances tend to be certain and particular to the user in concern (or the hardware in question) and are much harder to fix in a general-purpose guide like this.

What have the right to Be Done around It?

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

Finding hardware love in the time of coronavirus requires being ready to spend more money 보다 usual in part cases. If you desire to purchase a consumer GPU because that gaming, it’s a negative time for doing so. You deserve to expect to salary 1.5x MSRP or greater at the moment. This is much better than the 3x MSRP cards were marketing for previously this year, yet it’s not a case anyone regards as good.

If you room attempting to upgrade her general-purpose PC, look at at 2 characteristics: RAM and storage. If you have an old maker stuck ~ above a spinning tough drive, examine into whether it deserve to be upgraded to an SSD. Also some laptops have the right to be thusly equipped, though whether your mechanism qualifies relies on its storage interface and also how user-accessible it is. When upgrading such a device is the end of the limit of this article, there are options.

The difference between a ram upgrade and an SSD upgrade for an older device is this: ram will help you if your trouble is that you don’t have enough RAM. Trying to operation an applications on 1GB of lamb if it requirements at least 3GB to operation well will lead to drive paging and also a the majority of slowdowns v erratic in its entirety performance. If you currently have enough RAM, though, more RAM won’t necessarily help. 4GB of ram is quite tiny for a new machine these days, but a 4GB machine should still be capable of running internet apps, indigenous processing, and other an easy tasks there is no a problem.

A solid-state drive, if you don’t have one, is no a replacement for RAM. Yet if lamb bottlenecks space not particularly your problem, a heavy state journey will rate up everything else. In a specific situation where a computer is low on RAM and needs an ext for an applications you must run, get the RAM. In a generic situation where you simply want to speed up the daily experience of using a PC and low lamb is not the problem, pick up an SSD. Also older SATA-only models have actually an bespeak of magnitude better latency than standard spinning disks.
