According to your description, I suggest you refer to the following information:
Everyone is concerned about the slowness of the system Due to system version, system file error, different machine hardware, hardware failure, network, installed programs, viruses, Trojan horses, rogue software and other reasons. The machine will slow down.
1, check the installed programs, check whether unnecessary or bundled software is installed when installing other software, and uninstall;
2. Press Windows+R to enter msconfig-Start- to see if there are any startup items that need to be disabled;
3. It is recommended to use a genuine system. After all, the genuine system files are complete, not deleted, relatively stable, and can be updated from time to time. The price of genuine home version WIN7 is around 400 yuan. You can still enjoy the system service of 1 year if you buy it in ASUS service center;
4. If a non-genuine system is installed, many system files will be deleted because many individuals did it, which will lead to instability or loopholes in the system;
5. Please use ASUS official website www.asus.com.cn Service and Support-Download Zone-Enter Machine Model/
If you don't know the specific model, you can choose automatic detection-enter the driver page-select the operating system installed on the machine/if the system installed on the machine is not provided by official website, it means that the machine is not suitable for installing this system, and it is recommended to install the system provided by official website; It is not recommended to use third-party software to update system vulnerability patches or hardware drivers;
6. Anti-virus software will update the virus database from time to time, and it can be fully scanned when it is free.
7. You can use optimization software to clean up used junk files, cache files, etc.
8. Clean the disk in Computer-Disk Partition-Right Click-Properties;
9. Save the backup data and replace the operating system; If you go to the service center to test the machine, please back up important information in advance.
10, after some attempts, if the machine is still slow, in order not to delay the use and deal with the problem as soon as possible, it is recommended to contact the service center for testing and handling.
