Factors that affect the speed of computer startup: 1. Operating system; if the operating system is too large, too many files, services, and software to be loaded during startup will slow down the startup speed. 2. Hardware; The impact of hardware on booting is mainly the CPU, memory capacity and hard disk speed. The boot program prestored in the motherboard will guide the CPU to call the data to start the system from the hard disk through the motherboard, and then run it in the memory space. Therefore, the CPU, memory The size and hard drive directly affect the speed at which the computer boots up. 3. Add-ons; the more add-ons there are, the more things have to be loaded into the hard disk and the slower the boot speed will be.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
The boot speed of a computer is determined by the operating system, hardware, startup add-ons, etc.
1. Operating system
The operating system has a great impact on the boot speed. Vista's boot performance is much better than that of XP (it is better A lot), however, because the Vista system is too large, the files, services, software, etc. that need to be loaded during startup are several times that of XP. Therefore, the two factors work together to make Vista startup slower.
And the computer systems used by many domestic friends are pirated. These systems have built-in things that occupy system resources, especially systems with Trojans and viruses embedded in them, which will cause the computer to start slowly.
In this case, you can only reinstall the system. Although it is not necessary to install the genuine version, you should try to install the pure version. After the system is installed, the boot will return to normal.
2. Hardware
The main impact of hardware on booting is CPU, memory capacity, and hard disk speed. The motherboard mainly affects the performance of each hardware.
CPU actually does not have a great impact on boot speed. Of course, if your CPU is really poor, it will definitely affect your boot speed.
The impact of memory cannot be ignored.
As the system and software versions are iterated, the requirements for computer configuration are getting higher and higher. If the user changes the system and finds that the computer starts up very quickly. Slowness is mostly caused by insufficient memory. After the user presses the power-on button of the computer, the boot program pre-stored in the motherboard will guide the processor (CPU) to call the data to start the system from the hard disk through the motherboard, and then run it in the memory space. The size of the memory directly affects the speed of computer startup.
If you encounter this situation, either reduce the system version or increase the memory module to shorten the computer boot speed.
Hard disk, the hard disk has the greatest impact on boot speed.
If you think about it, the system files are all placed on the hard disk. When you start the computer, you have to read these files and save them into the memory or load them. So, is the capacity of the hard disk larger? The faster the big startup? No, it depends on the speed of the hard disk. The continuous reading speed and seek time all have an impact, especially the seek time of the hard disk! ! ! The shorter the seek time, the more efficiently fragmented files can be read, and the faster the system can start.
When the SSD hard disk group is raid0, due to the near-0 seek time and ultra-high reading speed, the system startup can be completed within a few seconds. Comparing the startup of a Core i7 920 7200 rpm hard drive with a Core 2 Duo E8200 SSD raid0 hard drive, the SSD configuration is obviously significantly faster at startup.
3. Add-ons
The more add-ons, the more things the hard disk has to load, and of course the boot speed will be slower.
In order to increase the frequency of users opening software, many software vendors will force, actively or default to set the software as a startup item. If there are only one or two software, the impact on the computer's performance will be small, but if there are ten Several or dozens of them will cause the computer to start very slowly. However, this state is quite special. The user starts the computer and enters the system faster, but the waiting time on the desktop is longer. The user can rely on this to determine whether it is caused by too many startup items.
When encountering this situation, you can use protective software such as 360 Security Guard and Computer Manager to clean it up. If you do not know how to use this software and the system has not been reinstalled for a long time, just reinstall it directly. Cleaning is more thorough than using this type of software.
