This article introduces how to solve the problem of network card caused by Windows computer overclocking. The content is very detailed. Interested friends can use it for reference. I hope it will be helpful to you.

Failure phenomenon: a friend's computer, its main configuration is: P42.4A CPU, Onda 865PEN motherboard (integrated network card), two Kingmax DDR400 256MB memory, Seven Rainbow popular 5700 graphics card and so on. Some time ago, the phenomenon of frequent disconnection occurred, and then the system became slow after boot, and the web link could not be opened. You need to enter the address in the IE address bar before browsing, and so on.

Troubleshooting: after booting into the desktop, the mouse began to disobey, the running speed is very slow, press "Ctrl+Alt+Del" to open the task manager and found that the CPU occupancy rate has reached 100%! In the process, we can see that the program named Explorer.EXE takes up all the CPU resources, and the process can not be shut down. after restarting the machine, the system speed returns to normal, but after about half an hour on the Internet, it is offline again. From the performance of the fault, the system is likely to be infected by the virus, upgrade rising antivirus software after running to check and kill did not find the virus, can it be caused by the antivirus software itself? An attempt was made to uninstall the antivirus software, but the problem was not resolved.

The damage or mismatch of the network card driver may also cause this phenomenon. After uninstalling the network card driver, reinstall the network card, after shutdown, start the computer to find that the system speed returns to normal, click the web link can be opened, but half an hour before the drop, but become very frequent. Check and know that my friend is using the Windows XP SP2 operating system. According to him, the Windows XP SP1 he used before has just been upgraded. Although the Windows XP SP2 operating system has greatly improved in network security, there are often a variety of network problems. So the author holds the mentality of trying, using GHOST to restore to Windows XP SP1, but the fault is still the same. Check that the network cable, interface, and ADSL Modem are all normal. The author stared at the screen in a daze and inadvertently saw that when the computer started the self-test, the frequency of CPU display was wrong, and so on! Is the computer overclocking? Ask a friend, he said a few months ago, a friend gave him more than one frequency of the computer. In front of the author's eyes, it is not overclocking that leads to the loss of the Internet, is it? Restart the computer, enter BIOS, reset the frequency to the standard value, and restart the Internet. It is found that after falling back to the original frequency, the probability of dropping the line is significantly reduced, but it still occurs from time to time. But my intuition told me that the problem seemed to be about to be eliminated. After blocking the integrated network card and replacing it with an ordinary PCI network card, I turned on the Internet and everything returned to normal.

The cause of the failure is somewhat complicated. First of all, the fault is likely to be long-term overclocking caused by damage to the network card (small damage), resulting in network instability. After an operation that causes driver damage (such as illegal shutdown), Explorer.EXE takes up all CPU resources.

Conclusion: overclocking will not only affect the sound card, but also cause damage to other accessories, especially the onboard network card. When you encounter a similar situation, you might as well consider the problem of the network card, so that the author will not make such a big detour.

About Windows computer overclocking causes the network card to have the breakdown the solution is how to share here, hoped that the above content can have certain help to everybody, can learn more knowledge. If you think the article is good, you can share it for more people to see.
