If there is no sound, there may be a problem with the sound card driver. Try using the driver wizard to reinstall the sound card driver. If that doesn't work, use a system disk that can automatically install the machine's hardware driver and reinstall the system, so that the problem of no sound in the system can be solved automatically and smoothly. You can use a USB flash drive or hard disk, and the installation speed is very fast. But the key is: there must be a system disk with good compatibility (compatible with ide, achi, and Raid mode installation) and can be automatically and permanently activated, and can automatically install the machine hardware driver, so that the system can be reinstalled automatically and smoothly. . The method is as follows:

1. U disk installation: Download a verified system installation disk file (ISO file), use ultraiso software to make a boot U disk for installing the system, and use this prepared system U disk After booting the machine, the system can be installed smoothly;

2. Hard disk installation: The premise is that there needs to be a Windows system that can run normally. Extract the "*.GHO" and "*.GHO" in the downloaded ISO file. "Install System.EXE" to the non-system partition of the computer, then run "Install System.EXE", press Enter directly to confirm the restore operation, and confirm again to perform the automatic installation operation. (Be sure to back up important data on drive C before executing!);

3. Graphic tutorial: How can I give you a detailed graphic version of the installation tutorial in this regard? Cannot be attached. It will be judged as a violation by the system. The address is at…………si xin zhong…………Yes! Hope to adopt it!
