"My computer is very slow", "it switches itself off", "it takes forever to start"… These are the questions we receive most at Master Informática from businesses in Benalmádena and Marbella. The good news is that, in most cases, a slow computer can be fixed and there is no need to buy a new one. We explain the most common causes and when it is worth repairing or replacing it.
Most common causes of a slow computer
1. An old mechanical hard drive
It is the number one cause. Many computers from five or six years ago still use mechanical hard drives, which are very slow compared with today's SSDs. Replacing the drive with an SSD is one of the cheapest and most effective upgrades: the computer can start in seconds instead of minutes.
2. Not enough RAM
With browsers full of open tabs, Office, email and management software running at once, 4 or 8 GB of RAM falls short. Adding memory is usually simple and inexpensive on desktops and many laptops.
3. Programs that start on their own
Over time, programs pile up that start with the computer and use resources even if you do not use them: updaters, manufacturer utilities, trial software… Disabling them frees memory and speeds up start-up.
4. Viruses, malware and adware
An infected computer can be slow, show pop-ups or open strange pages. As well as the performance problem, it puts your data and passwords at risk, so it should be checked as soon as possible.
5. A full or failing drive
When the drive is almost full, the system has no room to work smoothly. And if the drive starts to show errors, as well as being slow it may end up losing data.
6. Overheating and dust
Dust building up in fans and heatsinks makes the processor overheat and slow down to protect itself. An internal clean and fresh thermal paste can restore performance and extend the computer's life.
7. An outdated or cluttered operating system
A Windows installation with years of installs and uninstalls accumulates leftovers that slow it down. Sometimes the best solution is a clean reinstall, after saving all your data.
Repair or replace the computer?
There is no single answer, but these guidelines will help you decide:
- It is worth repairing if the computer is less than 5 or 6 years old, the problem can be solved with an SSD, more memory or a clean, and the processor is good enough for the work you do.
- It is better to replace it if the computer is very old and does not support current versions of Windows, if the repair costs almost as much as a new computer or if it has several faults at once (motherboard, screen, battery…).
- In businesses, you also need to consider lost time: a computer that often causes problems costs much more in working hours than replacing it.
What you can check before calling a technician
- Restart the computer (not just put it to sleep) and see if it improves.
- Check the free space on the drive and delete files you do not need.
- Open Task Manager and see which programs use most CPU and memory.
- Disable start-up programs you do not use.
- Run a full scan with your antivirus.
If the computer is still slow after this, it is best to have a professional run a full hardware diagnosis.
