After the computer overclocking, the network card has a solution

  

Symptom: A friend's computer, its main configuration is: P4 2.4A CPU, Onda 865PEN motherboard (integrated network card), two Kingmax DDR400 256MB memory, colorful popular 5700 graphics card Wait. A while ago, there was a phenomenon of frequent dropped calls. Later, after the system was turned on, the system became slow and the web link could not be opened. You need to enter the address in the IE address bar to browse.

Troubleshooting: After booting into the desktop, the mouse will start to listen, the running speed is very slow, press "Ctrl+Alt+Del" to open the task manager and find that the CPU usage has reached 100%! In the process, I saw that the program named Explorer.EXE occupies all the CPU resources, and the process can not be closed. After restarting the machine, the system speed returns to normal, but the Internet is about half an hour, and the line is dropped. From the performance of the fault, the system is likely to have a virus. After upgrading the Rising anti-virus software, it is not detected by the anti-virus software. Try to uninstall the anti-virus software, the fault is not resolved.

Damage or mismatch in the NIC driver may also cause this phenomenon. After uninstalling the NIC driver, reinstall the NIC. After shutting down, start the computer and find that the system speed is back to normal. Click the web link to open it, but the dropout that occurs only after half an hour has become very frequent. See that the friend is using the Windows XP SP2 operating system. According to his previous use of Windows XP SP1, just upgraded a while ago, although the Windows XP SP2 operating system has greatly improved network security, but often there are various network problems. So the author took the test mentality and restored it to Windows XP SP1 with GHOST, but the fault remains. Check that the network cable, interface, and ADSL Modem are all normal. The author stared at the screen, unintentionally seeing the computer start self-test, the frequency of the CPU display is wrong, and so on! Is the computer overclocked? Ask a friend, he said that a few months ago, a friend gave his computer more than once. The author's eyes are bright, will not be overclocked and cause the Internet to drop? Restart the computer, enter the BIOS, reset the frequency to the standard value, and restart the Internet. After finding that the frequency was dropped back to the original frequency, the probability of dropping the line was significantly reduced, but it still appeared from time to time. But the intuition tells me that it seems that the fault is to be eliminated. After the integrated network card is blocked and replaced with a normal PCI network card, the Internet is turned on and everything is back to normal.

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

Summary: Overclocking not only affects the sound card, but also causes damage to other accessories, especially onboard NICs. When you encounter a similar situation, you may wish to consider the problem of the network card, there will be no such thing as the author has circled such a big bend.
