Win8 no sound, can't connect to the network, resolution solution

Before the release of the developer preview in September, I installed the Windows 8 Developer Preview on a low-end notebook bought in 2008, and encountered the sound icon. On the last fork, there is no sound and resolution problem (14-inch notebook 1280*768 is the best resolution of this notebook, only 1024*??? after Win8), then manually installed by using the corresponding graphics driver on Win7 Solved the resolution problem, the sound method did not work in the same way. After the release of the consumer preview version on March 1st, the Win8 consumer preview version was also installed on this notebook. At this time, it was found that the basic driver that comes with the system installation has made the sound problem no longer a problem. Sound, but the display resolution is still 1024. But this time I chose another method to solve it! In the Control Panel - Device Manager, click on the Display Device. Right-click on the key--Update Driver Software--Automatically search for updated driver software. The machine is connected to the Internet normally, so the available updates are searched, the download is automatically downloaded, and the driver update is completed in a few minutes. The screen resolution becomes clear after the moment the computer screen flashes at a certain moment, familiar! This time is already the best resolution. Therefore, it is recommended here that there is no sound after installing Win8. When the resolution is out of the problem, choose to use the above mentioned method to update the driver. If you are unable to connect to the network, it is recommended to find your own network card driver, online search and download, or In the Win7 system, the driver wizard is used to drive the software to automatically identify the download. Then select the installation in the Device Manager of the Win8 system. It is not recommended to install these automatic identification download driver software directly on Win8. These softwares are not perfectly compatible with Win8. Some people have installed it on Win8. It is used, no problem, but many people install these software directly lead to crashes, crashes, etc. problem. So for the time being, it is not recommended. If you are a dual system, then installing these software downloads on Win7 will have no problem! In this notebook installed Win8 consumer preview version also installed Win8 on a new desktop, after installation, there is no problem, personal guess is because the motherboard used in this desktop, graphics card, etc. are relatively new products Therefore, the basic driver is relatively perfect, and it is easy to have problems with some machines that are purchased earlier. Have you found out? Driver problems, some can solve, some can't, can only wait for the official update, so when you see your computer display is normal, can access the Internet, when there is sound, try not to use some software to detect and install more drivers.
