Performance problems on laptops are very common, however, these problems are usually very easy to solve. In this post I will explain in detail why laptops and desktops decrease their performance, so you can easily and accurately diagnose the cause of the problem and I will also show you how to solve each one step by step. In this way, you will not only improve the performance of your laptop, you will also significantly increase the life of your computer.

Part 1: The Ultimate Guide to Fixing a Slow Dell Laptop Computer

Have you ever wondered why computers decrease their performance over time? So, this post is for you, because despite being a very common problem, it is easily solvable.

“Q: I bought a Dell Laptop a year ago and it is getting slower, what’s happening?

There are many factors that influence the proper functioning of your computer and it is highly recommended that you know them so that you can prevent such problems.


Part 2: What Are Dell Performance Issues?

Knowing if your computer has performance problems is very easy, here I will tell you about the most common symptoms and how they can be generated.

It is very slow and unresponsive

This problem is strongly related to damage or physical wear on HDD disks. Laptops are common work tools and therefore and they constantly have to be transported from one place to another. It is important to remember that HDDs are extremely fragile components and any sudden movement, shock or voltage variation can permanently damage them.

It keeps freezing now and then

Freezing problems are very common in computers with insufficient RAM. This is because when you open a program and your RAM is saturated, the RAM has to free up space to store new information and must perform this process with more frequency, generating a bottleneck and slowing down the rest of the processes.

It’s extremely slow to start up

Again, this may indicate that your hard drive is damaged. The reason why it takes too much time to an operating system to start is because it has not yet been able to finish the booting tasks, such as running programs, mainly due to low data reading speeds.

It runs hot quickly and overheats

If your computer heats up more than usual, it is very likely that your ventilation system is clogged with dust. The biggest source of heat in your computer is the processor, but you can keep calm, if your processor were damaged, you could not turn on your computer, in addition, it is very difficult for a processor to be damaged and when this happens, it is usually due to variations in voltage.

Other performance issues

Remember that desktop computers, like laptops, were designed to work properly and are subjected to rigorous quality controls before being marketed. Any malfunction or anomaly is a sign that something is not going well. It is important to identify the cause of the problem in order to solve it before this has an impact on the health of your components.

The method to access this function varies depending on the model of your Motherboard and the version of your BIOS but all BIOS have this tool included.

Fix 9. Prevent overheating by with a fan system cleaning

High temperatures are a very common problem in all types of computers, and this is due to three reasons.

  1. Performance reduction: All the components of your computer require an energy supply and this energy generates heat. Computers are designed to reduce their performance when they are working at high temperatures in order to reduce energy consumption and thus regulate the temperature of their components to protect them from possible damage caused by heat.
  2. Insufficient ventilation: All computers have a dissipation system, usually composed of radiators and copper pipes connected to a fan. These dissipation systems are very efficient, but it is a fact that, by manipulating the air flow of their surroundings, the fans will accumulate dust and with the passage of time, this dust will be able to drastically reduce the air flow, generating thermal throttling.
  3. Thermal paste in poor condition: The thermal paste is responsible for creating a link between the processor and the radiator so that the ventilation system works properly. The thermal paste hardens over time and this causes it to lose its heat conductive properties and when this happens, thermal throttling problems appear.

For all these reasons it is highly recommended to keep your computer fans clean and clear, and in addition to have an extra thermal paste in case it is necessary to replace it.

Fix 10. Update software programs

Programs and applications usually have automatic updates whose purpose is to improve performance and compatibility; however, you can search for and install more recent versions of your programs.

Fix 11. Upgrade the RAM

If your computer reduces its performance when opening applications or browser windows, it is possible that the cause of the problem is because your RAM is insufficient. You can check it by pressing Control + Alt + Del, this will open the “Task Manager” tool, with which you can monitor the consumption of application resources; the higher the percentage of consumption, the computer will have a lower performance.

Fix 12. Replace an HDD with an SDD

If none of the above methods solved the problem, it is very likely that the problem is in the health status of your HDD. HDDs are fragile components because they internally use a disk and magnetic head that can be damaged relatively easily by shock, constant movement or voltage variations.

To solve this problem, you will have to replace the damaged disk with a new one. It is highly recommended to use an SSD instead of an HDD since, although they tend to have a lower storage capacity, these are much more reliable and faster. Replacing your HDD means that you will lose all the information you have stored in it, however, there is a way to recover all that information even if the HDD is damaged.

If you are looking for a reliable way to recover your information, Recoverit Data Recovery is a professional data recovery tool that can recover and repair damaged disk files with great ease.

I will show you how to use Recoverit.

Step 1: Select a Drive

Launch Recoverit and look into “Hard Disk Drives”. Your drive will be there. Select and click on “Start”.

Conclusion

As you have noticed, it is not difficult to solve the performance problems in a computer, many times, the performance problems are usually related to the overheating of its components, mainly in laptops, since its fans and air intakes are smaller and easier to clogging; however, the second most common cause, is a bad hard drive and although replacing them with an SSD is usually a definitive solution, it is a headache to lose your information, fortunately, Recoverit allows you to recover and even repair the files of a hard drive, even if it is damaged.
