If the computer slows down, there is no need to reinstall the system. You can speed up by simply adjusting: 1. Clean the startup items, disable unnecessary startup programs such as QQ and WeChat, and improve the startup speed; 2. Free up space of the C disk, delete temporary files, transfer large files, and avoid the full load of the hard disk to affect the operation; 3. Check the background process and close the invisible programs that occupy resources, such as browser plug-ins or abnormal processes; 4. Update system patches and hardware drivers to improve compatibility and performance. Through the above steps, most old computers can significantly improve their operating speed and can continue to use without complicated repairs.

It is really annoying to slow down your computer, especially when you are in a hurry to handle your work or want to relax and play games for a while. In fact, in many cases, the problem is not that complicated, and it is not necessary to reinstall the system. With some simple adjustments and cleaning, most computers can significantly speed up.

1. Clean the startup item and don't let the program start secretly.

Have you noticed that the CPU and memory have started to "work overtime" before opening any software after booting? This is likely because too many programs start by default.
The solution is simple: Press Ctrl Shift Esc to open the Task Manager → Click the "Start" tab → Right-click the unwanted program and select "Disable".
Common software such as QQ, WeChat, and Steam are all self-activated by default, but they can actually be opened as needed. After doing this, the boot speed will be much faster and the system will be lighter.

2. Free up disk space and don't let disk C be breathless

Especially for computers that use traditional mechanical hard drives, when the C drive is almost full, the system operation will become stuttered.
You can do this:

• Delete temporary files (Windows can run %temp% cleaning)
• Uninstalling infrequently used software
• Use the system's own "disk cleaning" tool
• Transfer large files or information to disk D or other storage devices

If you are using a solid-state drive, you should leave some free space, otherwise the entire system will slow down as the writing speed drops.

3. Check the background process and don’t let the “invisible killer” occupy resources

Sometimes, even though you don’t have a few software open, your computer is very stuck. At this time, you have to look at the “Process” tab in the task manager.
Some programs quietly eat up a large amount of CPU or memory resources in the background, such as opening too many tabs by the browser, updating services in the background, scanning of antivirus software, etc.
suggestion:

• Close unnecessary browser plugins
• End process with extremely high occupancy (be careful not to interfere with the system-related processes)
• Check the resource monitor regularly to see which programs are "resident killers"

4. Update the system and drivers, and don't ignore the details

Many people think that the slower the system is used, because of aging. In fact, it may be that the driver is not updated or the system patches are not fully installed.
Especially graphics cards and motherboard drivers, performance and compatibility can often be improved after updates.
The Windows system can enable automatic updates in settings, and the hardware drivers can be detected and updated with tools provided by manufacturers. For example, Intel and NVIDIA have their own driver assistants.

Basically, these operations are all about it. It is difficult or not, but it can really solve the problem. Many people just are too lazy to make trouble, but endure the lag in vain. Try it, maybe your old computer can be fought for a few more years.
