Why computer becomes slow




















I promise you can do it on your own. Well, technically on your own -- I'll walk you through how to fix your slow PC by digging into Task Manager, controlling how many apps open at startup and a few other tips and tricks I've learned along the way. Think of Task Manager as a window into your PC's health. The app gives you insight into what's taxing the processor, how much memory something is taking up and even how much network data a program has used.

An easy way to open Task Manager is to right-click on the Taskbar and select Task Manager from the list of options. Task Manager's default view doesn't show a lot of information beyond which apps are currently running handy if you already know if you want to close one out.

To view what really matters, click More Details in the bottom left corner. By default, this list is broken down into Apps and Background Processes. It's refreshed constantly, with the various columns constantly updating. My advice is to let Task Manager run for a few minutes and watch it.

Watch for apps that shoot up to the top of the list, then disappear a few seconds later. Look for processes that stay at the top of the list with high memory or CPU use. Not sure what a process is? Google its name to find out more. To close an app or process that you suspect may be partly responsible for slow performance, click on the listing then click End Task.

There are far too many apps and services to create a succinct list of what's likely slowing down a PC, but that doesn't mean there aren't likely culprits. It then takes longer for the system to find each piece of data. Defragmenting your disk will speed this process up. Find out more about defragmenting your hard drive. You can select the process to run on a regular schedule, or you can click Analyze Disk and determine if the process needs to be run immediately. Identifying hardware that might be due for an upgrade can not only make an older and slower computer feel new again, it can also be significantly more cost efficient than purchasing a new computer.

Two key pieces of hardware related to the speed of a computer are your storage drive and your memory. When it becomes out of date or slows down, it will make a noticeable impact in the performance of your computer. The key difference between a traditional hard drive and a solid state drive is the technology behind it. An HDD mechanically moves an actuator arm across a spinning platter to find each portion of data. An SDD, however, accesses the data digitally with flash memory chips.

This allows SSDs to retrieve data like documents, images, and videos more quickly while using less power. Plus, they can be used with multiple systems and devices.

Unlike programs or videos that are permanently stored on the storage drive, memory stores data that is currently being used, allowing it to be retrieved quickly, functioning as a pool of resources for your system to get things done. The more memory you have, the more resources your system has at its disposal, meaning it can do things faster and handle more things at once. Adding more memory is a straightforward way to fix problems with slow performance when switching between apps and slow response times.

Upgrading your memory may sound intimidating, but it's actually quite easy. With a screwdriver, your owner's manual and a good how-to video, you can install new memory in just a few minutes. No computer tech required. Just a few small, manageable changes that deliver immediate and lasting results. A slow computer is likely because you have too many programs running.

Even if an antivirus scanner is installed on the computer, we recommend running a malware scan as well. Use the free version of Malwarebytes to scan your computer for malware. Verify that the Device Manager has no conflicts.

If any exist, resolve these issues as they could be causing your problem. To update a computer running Microsoft Windows, run Windows Update. To update a macOS computer, run Software Update. To upgrade the operating system, use the App Store. If your computer runs especially slow when you're using your web browser, considering disabling any browser plug-ins, add-ons, or extensions. Make sure you have the latest drivers for your computer hardware, especially the latest video drivers.

Having out-of-date drivers can cause an assortment of issues, including slow performance. We usually do not recommend registry cleaners. However, if you followed all the steps above and your computer is still slow, try running a registry cleaner on the computer. If you have had your computer for more than two years, you may need more memory.

By having enough memory for programs to run within memory, your computer doesn't need to swap information stored in memory to the swap file. If the hard drive light is continuously active, it's an indication the computer is frequently swapping information between your memory and hard drive.

One of the biggest bottlenecks of a computer is the hard disk drive. Make sure your computer and processor is not overheating. Excessive heat can cause a decrease in the computer's performance because most operating systems automatically reduce the speed of the processor to help compensate for heat-related issues. Dust, dirt, and hair can also constrict proper airflow inside your computer, which causes a computer to overheat.

Make sure your computer case is clean, and that the fans are not obstructed. Increasing the speed of the processor CPU can improve your computer's performance. There are two options for increasing processor speed: overclocking or upgrading. Overclocking a processor means increasing its speed beyond what it's designed to run stably. Furthermore, the processor itself must be capable of being overclocked. You would need to find the specifications for the processor in your computer to determine if it can be overclocked.

An overclocked processor generates more heat, thus requiring a more powerful heat sink and fan to pull the excess heat away from the processor.
