It is very frustrating to encounter the problem of computer startup/shutdown suddenly slowing down. PHP editor Baicao will delve into the causes of this problem and provide a series of practical solutions. The following content will provide you with a step-by-step guide to help you quickly solve the problem and restore the normal startup and shutdown speed of your computer, so that you no longer need to wait while processing computer tasks.
Cancel the quick startup and try shutting it down.
Replacement of the power supply will most likely not cause a huge difference in shutdown speed.
If the wifi speed on your mobile phone suddenly slows down, it may be because you have shared the network with others or there is a channel conflict.
The solution is as follows:
1. The wireless network may be shared with other people. When using the software to test the network speed, the network speed is very fast, but when used, it is very slow. This means that the problem lies in the software you use and the files you download. If the server that provides downloads is slow, it will be useless no matter how fast your internet speed is.
2. The network speed suddenly slows down, but the wired network speed is normal, and if it is ruled out as a line or hardware problem, then you should consider the problem of channel conflict, because wireless is now everywhere, and there is more than one wireless network where you live. Routers, their signals may conflict when transmitting, causing the Internet speed to slow down. This needs to be changed in the wireless router settings and it will be OK.
Extended answer:
The network speed of the wifi wireless router suddenly slows down. The steps to resolve the channel conflict are as follows:
1. http://192.168.1.1/ First enter the tp-link modification settings page and enter the wifi password to enter.
2. Click Wireless Settings-Basic Settings, and then you can see your wifi name, whether the channel you are using is automatic or selected, there are a total of 1-13 channels to choose from.
3. Click to turn on the WDS option and find a scan option below. It is used to check which channels are used by WiFi near you. The best WIFI channel is 1-6-11, these three channels! These three channels do not interfere with each other! And it has strong penetrating power! If most of your neighbors are using 1, then you choose 6 or 11 to avoid using the same channel at the same time.
4. This picture is the WiFi signal found near me. Of course, you can choose the nearest WiFi name and write it down. Don’t consider China Unicom’s public WiFi account. The closest one to me is liuxuhao 123, and they both use 6.11 respectively. So, I changed my channel to 1 and it was OK, and the download speed returned to the 1M level.
1. Clean the hard drive: If you encounter the problem of slow performance, the first thing you should do is empty the trash.
2. Turn off functions: If you have freed up excess hard drive space but the performance problem has not been improved, you can try turning off some functions again.
3. Monitor CPU and RAM: Use Activity Monitor to see which applications and processes are taking up the most CPU and RAM resources.
4. Generate system diagnostics: Run system diagnostics to generate a diagnostic report for your Mac. The files contained in it allow Apple to investigate any problems with your Mac.
Tout d’abord, comprenons pourquoi les ordinateurs deviennent de plus en plus lents à mesure qu’ils sont utilisés. Les raisons sont les suivantes : Premièrement, il y a trop de fichiers indésirables. Après une utilisation prolongée du système, un grand nombre de fichiers inutiles (fichiers indésirables) seront générés sur le disque système, occupant certaines ressources du système et provoquant un ralentissement du système. Cela nous oblige à supprimer les fichiers indésirables. pour améliorer la vitesse de course. Deuxièmement, la mémoire virtuelle est trop faible. Il existe un très gros fichier d'échange de données sur le disque dur. Il s'agit d'un emplacement réservé par le système pour la mémoire virtuelle pour le stockage temporaire. Il est souvent utilisé par de nombreuses applications, le système doit donc accéder fréquemment à une grande quantité de données. mémoire principale. Par conséquent, la vitesse d’accès à ce fichier constitue un facteur très important affectant la vitesse de l’ordinateur ! Troisièmement, il y a trop d'icônes sur le bureau et trop de polices sont installées. Quatrièmement, le système est infecté par des virus. Si votre ordinateur est infecté par un virus, le système ralentira considérablement. Après l'invasion du virus, il occupe d'abord la mémoire comme bastion, puis l'utilise comme base pour commencer à se copier sans fin dans la mémoire. À mesure qu'il devient de plus en plus grand, il occupe rapidement une grande quantité de mémoire système, ce qui est normal. temps d'exécution du programme. Il ralentit ou même ne démarre pas en raison du manque de mémoire principale ; dans le même temps, les programmes antivirus forcent le processeur à exécuter et à exécuter des programmes inutiles, ce qui rend le système toujours occupé, affectant ainsi le fonctionnement des programmes normaux. et provoquant un ralentissement de l'ordinateur. Cinquièmement, il y a trop de fragments informatiques. Si votre système a été utilisé pendant une longue période et que vous installez, téléchargez et supprimez fréquemment certains logiciels, cela créera beaucoup de fragmentation dans le système, entraînant un ralentissement du système. Sixièmement, il y a trop d'éléments de démarrage. Plus il y a d'éléments de démarrage au démarrage, plus l'ordinateur fonctionne lentement. Le logiciel de sécurité montre que parfois la vitesse de démarrage ne peut battre que moins de 3 % des utilisateurs dans tout le pays, ce qui montre l'énorme impact des éléments de démarrage sur la vitesse de l'ordinateur. Septièmement, il y a trop de programmes pour résidents. Qu'est-ce qu'un programme résident ? Les programmes résidents sont des programmes chargés lorsque l'ordinateur est allumé et ces programmes sont appelés programmes résidents. Les programmes résidents ralentissent non seulement le processus de démarrage, mais consomment également plus rapidement les ressources informatiques et la mémoire. Ces facteurs peuvent être résolus grâce à des opérations spécifiques, mais une chose est qu'une fois que l'ordinateur réinstalle le système, la plupart des facteurs ci-dessus qui affectent la vitesse de l'ordinateur reviendront essentiellement à zéro, il est donc inévitable d'augmenter la vitesse de l'ordinateur.
The repair method is as follows:

8. The decompression speed suddenly slows down?
1. The file to be decompressed is very large. For example, if the compressed file is as large as 4G, then the decompression will be very slow because there is a lot of data to be processed.
2. The computing speed of the computer’s CPU. Decompression requires the computer’s CPU to restore the files before compression. Poor CPU performance will result in slow decompression.
3. The system has insufficient memory. A lot of data is in the memory when decompressing. If the memory is insufficient, part of the decompression must be saved. Then decompress and then save, the speed will slow down.
4. The speed of the computer hard disk. If the performance of the computer hard disk is poor, it will also cause slow decompression due to slow reading and writing speeds.
5. Insufficient temporary computer space, insufficient system resources, etc. will also cause slow decompression.
9. CSGO mouse speed suddenly slows down?
1. If it is a network problem, try checking the network status to see if there is a problem with the network;
2. The graphics card is a bit bad, and the computer cannot drive it with full special effects turned on, vertical synchronization To turn it off, reduce the special effects;
3. The relationship between fps is not particularly big, but it must be at least 100 or above;
4. Remove the mouse from the control panel with high precision.
