The more the computer runs, the slower it's going to be.

Software Reason:

Workaround:

1. If the computer installs multiple anti-virus software, please keep only one test, because the anti-virus software may have the product conflict.
2. Check CPU utilization is too high, such as excessive, try to end the excessive use of the process program. If the computer infected with the virus, will also cause some of the process occupancy rate is too high, we recommend that you can try to upgrade the virus library to the latest version after the antivirus test, eliminate virus problems caused.
3. Try to adjust the virtual memory.
4. Cleaning with the Junk File Cleanup tool carried by software such as third parties can also be cleaned up with Windows features, such as the Disk Cleanup feature and the disk defragmentation feature for optimization.
5. Uninstall software that is infrequently used under the system by adding a removal program.
6. Through the operation of the input "msconfig" command, optimize the boot start item, improve the system start speed.
7. If your operating system has not been reinstalled for an extended period of time, it is recommended that you also use the above methods to back up important data and reinstall system tests.

Hardware-related issues

1. Host hardware configuration is not enough, generally reflected in the machine to replace the higher version of the operating system, running slower, this situation requires you to upgrade the hardware test.
2. The hard drive has the physical bad road or the hard disk other fault, causes the machine to run slowly, if you have the experience which uses the third party software to detect the hard disk, may try using the third party software, detects the hard disk to have the hardware fault.
3. Other hardware and other reasons, such problems need to use special tools for related testing, recommend you if convenient, send to the nearest Lenovo service outlets to help you detailed detection.

One, hard drive bad road

Computer long-term use, the hard disk caused by the wear will be very large, especially such as Internet cafes, such as long-term boot and non-normal shutdown of the computer, its hard disk loss will be greater, hard disk damage is generally from a small number of bad start, and then gradually the worse the larger, Also some hard drive is due to poor power supply or hard drive quality and cause the hard drive motor running speed down, that is, the hard disk board part of the damage.

We should develop good habits, do not "illegal shutdown", to allow the system to shut itself down, as far as possible to reduce the damage to the hard disk, if you are anxious to shut down, you can also use the "Fast shutdown" software, or use the "Task Manager" and then hold down the CTRL key and then point task Manager shutdown, this speed is very fast, The computer shuts down in about 2-5 seconds and does not damage the hard drive. When the hard drive has a bad way to distinguish the division, use the partitioning tool to find and separate the corresponding bad parts, do not let it continue to expand. Another hard drive if suddenly the noise is too large, it is likely to be bad omen, quickly get professional place to overhaul.

Second, the memory is too small

Today's system is very eat memory, such as XP system at least 256MB, if it is 128, it will be very card machine, and play a large game on the 512MB of memory even more, and eat more memory system is vista, System basic operation will need 512MB, If you want to run smoothly on the need for 1G of memory, playing a large game can be imagined ... No 2 G is going to be a big card.

Third, attention to heat dissipation

The summer has come, the heat has become a very important problem, we know that the computer in the CPU after the temperature rise in the hot summer CPU internal temperature is very high, CPU manufacturers to protect the CPU, the CPU temperature is too high when the automatic reduction of the frequency to not burn the CPU, the other motherboard also has high temperature protection, When the CPU temperature is too high will automatically power off, so pay attention to the CPU temperature, when the temperature is too high when the CPU will automatically change the "card machine." In the winter also should be careful not to let the computer too cold, temperature too low will lead to the machine.

To solve the heat dissipation method, regularly clean the dust inside the computer, in particular, CPU fans must be wiped, wipe the silicone, it is not good to change a more powerful fan, but some people are accustomed to open the chassis, so that the cooling effect is relatively good, but it may be injured inside the chassis, so easy not so "bright"!

So how to simply judge where the computer is stuck?

First, open "task Manager" to see whether the CPU load is too high, or the memory is all occupied.

Second, in the running of the program or the game to listen to whether the hard drive for a long time to see if the hard drive lights flashing non-stop, if the memory is too small will aggravate the hard disk burden, if the hard disk has bad block will run some programs too slow, while other programs are normal.

Third, regularly clean up the garbage files, regular anti-virus, etc., if the original system of a normal suddenly one day the system is particularly slow, it may be caused by the virus.

At the same time to develop a good habit of operating the computer, do not "illegal" shutdown, do not always put a CD-ROM or insert a U disk in the computer, regular cleaning of the internal dust inside the chassis, especially in the summer to pay attention to the problem of heat dissipation. Let our love machine always protect the optimal state, for our efforts to dedicate her youth bar!

Four, the CPU is not strong enough

Now the system and some programs are also very eat CPU, especially some large online games, in many places is very card machine, which requires that your CPU chip can not be too low, like 1 yang. X This kind of CPU is basically eliminated by the game, but now the CPU development "very speed", the dual core has been very common, the next step is a quad-core, that is, generally the CPU speed has completely exceeded our needs, Even if it is like Sai Yang 2.8D such a very classic CPU, playing a large 3D game will not be very card, if it is very card and it is possible that your video card does not keep up or your memory capacity is small, not necessarily the problem of the CPU.

Everyone in the "task Manager" can see the CPU load, look at what the program is compared to "card machine", in the end is the card in what place, to do the heart know, the future upgrade is also convenient.

Too many startup software

1, the computer's startup too much lead to slow starting speed. Click on the lower left corner of the computer to start >> run, and then in the Run window Input msconfig command and enter, and then click on the Start button, and then in the interface, only retain Ctfmon.exe Input method and antivirus software two programs can be removed from the other hooks.

Computer knowledge

2, turn off the system properties of some special effects. On the desktop My computer clicks the right mouse button, then in the Drop-down menu to select Properties, and then in the pop-up interface, we click on the Advanced button, in the Advanced interface, we click on the performance section of the Settings button, and then in the pop-up interface, we choose to adjust to the best performance.

3, on the computer desktop click the right mouse button, and then select Properties, and then in the interface we click on the Desktop button, and then set the background to No, color set to black. Because the desktop background on the computer's boot speed is very large, recommended to remove.

4, then the previous step of the settings, click on the Screen Protection button, and then set the screen protection to none.

5, then click on the appearance of the button, and then follow as shown in the settings.

6, the icon on the desktop as far as possible not too much, to retain a maximum of 10 or so. Shortcuts exist on the desktop, not often, but do not want to delete, we can click the right mouse button on the desktop, and then select the Arrange icon, and then choose to run the Desktop Cleanup Wizard.

7, click on the lower left corner, and then in the pop-up interface to select the Run command, and then enter regedit and return, open the Registry command, and then in the inside according to the path to find Hkey_local_ Machinesystemcurrentcontrolsetcontrolsessionmanagermemorymanagementprefetchparameters, Then in the right side of the interface to find Enableprefetcher, click the right mouse button to modify, set the value of 1, which can reduce the boot time when the scroll bar.

8, the proposal often clean up garbage, uninstall the unused program, and then the IE browser cache files and system disk to distinguish.

9, the normal use of high memory software, it is recommended to turn off the anti-virus software monitoring function, so that can be a good saving a part of memory
