What are your computer busy?

Page 1st: does it take 2 minutes to start the system? How to start a computer

In September 13, when everyone started learning to use the computer, I am afraid the first operation was to start the computer. When xiaobian was just getting in touch with the computer, I was once warned by "kindly" that it was a university question. Think about the past, maybe it was just a joke, or just an irony that many people did not pay attention to the use of computers at that time-many so-called computer courses at that time had no practical significance.

Nowadays, with more and more new technologies and operating systems constantly updated on the CPU, people may have to look at this operation from a brand new perspective, because the 2-minute boot time is still crazy, reading the scroll bar in front of the computer may be a headache that many netizens have to endure every day.

The following small series will provide several optimization methods to speed up computer boot for netizens within their own knowledge, hoping to help the majority of netizens.

Page 1: What is the computer busy during startup? How to speed up boot

Many netizens are confused that the page switching during startup, especially the scrolling of the progress bar, is set only to display "high-tech? Not to mention that many of the small editors have asked such questions.

In fact, the computer boot process is very complicated. The dazzling boot animation of wiundows7 is composed of more than 100 frames. So what are the computers doing when they are started? After pressing the power key, the power supply starts to power the device. The voltage is unstable at this time. The motherboard control chipset sends a reset signal to the CPU, and the CPU starts initialization. After the voltage is stable, the CPU starts to execute commands, jump to the startup code in the system BIOS, the system starts power-on self-check, and then the system will call the video card BIOS to initialize the video card. At this time, the computer has the first screen, which simply displays the main information of the video card, the system then initializes the system using other BIOS settings, and then displays the system startup information, after device initialization and detection, the system BIOS and the operating system exchange hardware configuration information data (stored in CMOS, the system code starts to start the device (usually a floppy disk, optical drive, or hard disk) according to the boot sequence in the BIOS. When the hard disk is reached, the system BIOS reads the Master Boot Record on the hard disk, the primary Boot Record finds the first active partition from the partition table and executes the Partition Boot Record in the partition. The Partition Boot Record starts reading and executing IO. SYS is the initialization of important system data, followed by GUI (graphical user interface) boot and initialization until you enter the operating system interface.

From the above process, we can see that hardware initialization, detection, and startup are rather complicated, the time spent in this process is closely related to the speed at which the CPU executes related commands and the running speed of the memory, hard disk, and other devices, in addition, some software operating systems need to start random startup items during startup. the time consumed is proportional to the number of startup items.

Page 3rd: optimizing the acceleration of startup by selecting strong configurations during boot

From the previous page's boot process analysis, we can conclude that there are two factors that affect the boot speed, one is the running speed of hardware devices (such as CPU efficiency and speed, memory frequency, and hard disk read speed ), the other is the number of add-ons at the startup of the operating system and the optimization of the operating system.

For the first reason, all we can do is to make our hardware run faster as much as possible. In addition to purchasing more advanced hardware, such as CPU with higher performance, we can also perform proper overclock operations, in any case, we must invest money here, because even if the frequency is too high, the overspeed is a "technical activity" For many netizens, it can only be said that the processor and related hardware are not super-powerful by taking one, and the risks of overclocking also increase the requirements for heat dissipation and power supply.

For the second factor, here we can provide some system optimization measures to minimize unnecessary time consumption.

Page 4th: boot settings focus on Guide Bar settings

Next, let's take a look at how to shorten the startup time of the computer system. First, after entering the system, click the Start Menu, enter msconfig in the search box, and press Enter.

Go to the system configuration page

Generally, the pop-up interface is the normal startup selected by default. The mini-editor's computer is optimized here, so the display is different. We switch to the "Boot" column.

Set Optimization in the Guide Bar

In the new interface, we need to operate on three items. First, we can select the option before the GUI-free guide. In this way, the system will no longer display animation marks during startup, the next timeout item can be set to a short time, but it is recommended that you do not set it to less than 3 seconds, especially when the hard disk is equipped with multiple systems, give yourself sufficient time to choose, this is the waiting time for you to choose between multiple systems (if multiple operating systems are installed) when you start the system. The last option that can be adjusted is the advanced option, in the new page that appears, you can check and set the number of processors. If the platform has multiple CPUs, acceleration can be performed.

Page 5th: The fewer boot items, the better? How to properly set

It is undeniable that we need to apply some software almost every time we start the system, and the "random start" feature brings us convenience, however, this convenience brings about an extended boot time, and many netizens have also encountered a number of software automatically joining the ranks of random boot items, which greatly increases the unnecessary boot time.

Token) There are two items in total. Of course, if a netizen wants to start software such as QQ at random, he can also keep the check mark before the corresponding option (if it is not checked, it means it is not started randomly ), after the operation is complete, select the application or directly Select OK.

Page 6th: optimize and continue acceleration after 10 seconds

After the above operations, many netizens may be able to control the boot time within 20 seconds, some users with high computer configuration may have controlled the boot time within 10 seconds and no longer have to wait for the boot time. How can they continue to maintain this smoothness after the boot?

Set to cancel sleep

Here are some suggestions for system optimization. First, if you do not use sleep and sleep, you can cancel the settings in advanced power management, then, enter "powercfg-h off" (excluding quotation marks) in the Start Menu → search box to cancel the hiberfile of the Sleep file with the same size as the memory on the drive C. sys.

However, in general, you cannot see this file, because the system hides this part of the file by default (you can open it in the graphic method ), however, you may also find another hidden large file, pagefile. sys.

Page 7th: reasonably set the virtual memory to truly achieve their desired needs

Pagefile. sys is a virtual memory file in Windows. In general, it is mainly used to virtualize some hard disk space into memory when the physical memory capacity of the system is insufficient, that is, it plays a standby role.

However, virtual memory is not used only when the physical memory is insufficient. virtual memory may also be used when the physical memory is sufficient, but the hard disk speed is far from the memory speed, even solid state disks cannot compare with the memory speed. How can we force the system to "squeeze out" physical memory? Settings are required here.

Set virtual memory

As shown in, here, we can go to the virtual memory settings in advanced system settings in sequence, first cancel Automatic Management, and then try to set it in non-system partitions and capacity settings, we recommend that you set the maximum value below 1 GB memory to 1024 (MB by default, and the minimum value can be set by yourself as needed) or higher, users with 1 gb-2gb of memory can set the memory to 512 MB (if vista or Windows 7 is used, it is recommended to set the memory to 1 GB). For users with 2 GB or more, we do not recommend that you do not set the virtual memory, because some software sometimes still uses virtual memory, and many games also call virtual memory at a certain time, this time can be like small series (small series is 2 GB physical memory) the value ranges from 256 MB to 768 MB.

Page 1: How to make full use of large memory? Hard drive Acceleration

We all know that the biggest bottleneck of system performance is hard disks. In any case, the data required by the system always comes from hard disks, therefore, how to speed up the hard disk has become a major starting point to greatly increase the system speed.

　

Left: normal mechanical hard drive right: Memory virtual hard drive

Due to technical reasons, the speed improvement of hard disks is far behind the improvement of CPU and other hardware. To solve the hard disk problem, manufacturers also frequently make moves, the launch of SSD and recent capacity breakthroughs show this effort. However, the current high cost and high price of SSD prevent its popularity, hybrid hard drive has become a good compromise. Intel has been working hard in this field before, and as we all know, fast drive is a product of great success, however, many netizens are asking "Are there free lunches?

Ramdisk can Virtualize memory into hard disk

Thanks to a small software, we can enjoy "free lunch ". This software is called ramdisk. It can Virtualize a part of the memory into a hard disk, which greatly improves the Data Reading Speed. As for the specific operation method, many forums have detailed introductions, so I will not talk about them here.

●Summary

With the accelerated pace of social life, time has become an absolute luxury. "No time" is no longer an excuse for the past. "How can we save time ?" This has become a difficult problem for many people. We used to say "time is life". Now we may have to say "Life is time ", I hope this article will save you some time. (Source: PCPOP)
