Troubleshooting of various faults on the Main Board guide (1)

In the past few months, my company has successively created several Internet cafes. As they are compatible with machines, some problems naturally arise. The problem was finally solved successfully through troubleshooting on site and communication with technical staff of the manufacturer. The following are some examples of troubleshooting to help you with troubleshooting.
1. Why is the game "eclipsed"

04-August, Internet cafe host configuration: C2.4/845PE motherboard/HY 256MB memory/ST40G hard drive/GF4-440-64MB graphics/WIN98Se system.

This Internet cafe was previously used to upgrade CPU, motherboard, and memory. Because it was an upgraded Internet cafe, our company was only responsible for providing hardware and not providing system installation services, the software is developed by the customer.

On the third day after the hardware was installed, the technical staff of the Internet cafe called for assistance, saying that after they installed the system, the special animation effects of the "Frozen throne of warcraft" game were released, in addition, the effects of several games are not very good, and the game version and operating system version cannot be changed. How can this happen! We were surprised, so we went to the site.

Through on-site observation, the game screen is poor. Is it a video card? But not every one of them is like this! I decided to reinstall win98. After the system was re-installed, I began to install the main board driver. the technical staff of the Internet cafe was very enthusiastic and took the initiative to help install the driver. So I stared at the screen while installing the main board driver, I saw that he did not press F8 to enter the safe mode, but directly entered the system. The result is of course a blue screen.

I reminded him: After the driver is installed and restarted on the motherboard of the INTER chipset in 98 system, you should first enter safe mode, and then enter normal mode in two or three minutes. It turns out that they used to install the system in this way, because the previous motherboard was I815EP. After the motherboard is changed, the system is also operated according to the previous installation method. Although the blue screen is found, you can press ENTER or ESC to skip it. Is the problem here?

I restored the initial state of the system through the Dos mode registry recovery command, and re-installed the motherboard driver. After the driver and Direct8.1 are all installed, I started to install the Warcraft game. After the game entered, the screen effect was very good. It took more than an hour to find a network administrator who was good at this game. It was stable and all the screen effects were normal. Install other game tests. Everything is OK!

2, KT600-R motherboard "counter-terrorism problems"

04 years in September, net cafe host configuration: AMD x p2500 +/KT600-R motherboard/HY 256MB memory/st80 G hard drive/FX5200-64MB-8X platinum graphics/a low-end brand W power/8139D NIC/17 flat screen color display.

This Internet cafe is very urgent, and the sources of supply are also several suppliers. Our company provides the main board, video card, hard disk, and display, which is the core part. The trouble is naturally more.

98. After the system is installed, a problem occurs after the video card driver is installed. After the desktop is restarted, the system screen will be fixed! Restart again! I tried a lot of methods to reinstall the system and change the graphics card driver versions. I had been getting the video card driver for three o'clock P.M. in the morning. I suddenly thought of contacting the Technical Department of the manufacturer, fortunately, the motherboard and video card are the same brand of our company's agents, so I dialed the manufacturer's service phone number and told the technicians about the fault.

After communication with the technical staff, it is learned that the BIOS version of this motherboard is not compatible with the win98 system, resulting in the use of 8X graphics card will generate after the driver is installed, when the system starts to the desktop, the fixed failure occurs. The solution is to update the BIOS of the motherboard or set the working mode of AGP to 4X In the BIOS settings. Of course, the customer does not want the video card to work in 4X mode. I asked the technical staff of the manufacturer to send the BIOS update file to my mailbox and upgrade the BIOS file by ourselves.

The BIOS files are uploaded. How can I update the files on 70 hosts? I have carefully observed that the BIOS of the motherboard is AWARD version 6.0. Can I use the WINFlash program to directly update it on the Windows interface? I set the work mode of the motherboard to 4X, smoothly enter win98, copy it to the WINFlash program and the BIOS upgrade file of the motherboard, start the program and transfer it to the BIOS file to start refreshing, the refresh is complete smoothly, and everything works normally after the system is restarted. I restart the system again to go to BIOS settings, set the working mode of The AGP to 8X, save the settings, and exit the system!

Then install applications, games, and copies ...... (N words are omitted below) who knows that at noon the next day, when the network administrator of an internet cafe calls, many hosts are playing the anti-terrorism elite game, A false crash or fixed screen failure occurs in about 40 minutes!

When I got to the Internet cafe, I got a master who was playing the "anti-terrorism" test. It was about 45 minutes. The game screen was fixed, but the numeric indicator on the keyboard could still be switched, it indicates that the system has not completely died. I tried to switch to the desktop with the "ALT + TAB" combination key, and still can return to the desktop. Later, a colleague said that he blocked the Sound Card Test game. On the one hand, I used this method to find a game expert to test anti-terrorism, and on the other hand, I searched the internet for anti-terrorism game crash issues, at the same time, I also contacted the Technical Service Department of the manufacturer to further suspect that the problem was caused by the sound card driver.

After checking that the motherboard is integrated with the alc650 sound card chip, installed with the driver attached to the motherboard, version 3.59. According to the manufacturer's recommendation, the driver of version 3.61 is downloaded, I installed a new sound card driver on another computer for testing. After an hour of testing, the computer that blocks the sound card has no problem with anti-terrorism. It is also normal for the computer that installs the new sound card driver to play Anti-terrorism. Further, it is related to the sound card driver. I cloned a hard disk from the computer that installed the new version of the Sound Card Driver and replaced it with another computer with the same configuration for testing. After more than an hour of testing, it was normal to play anti-terrorism. As a result, the problem was solved by reinstalling the new audio card driver on all computers.

3, NF2-400 motherboard "troubles"

On July 22, November, Internet cafe Host Configuration: AMD flash dragon 2500 +/NFOCRE2-400PRO motherboard integrated NIC/HY 256MB memory/ST80G hard drive/FX5200-128MB-8X platinum graphics/Great Wall W power/17 flat screen color display/win98 system/80 sets.

This is the most troublesome installation and debugging work I have encountered. After the system was debugged, several problems were found:

A. the frozen throne single-host version of warcraft cannot run: Some hosts remain on the startup interface after opening the game. After investigation, we found that you only need to reinstall the motherboard driver and restart it.

B. the following error is reported when the office software of Office2000 is started on some hosts: Fortunately, if there is a backup file on the hard disk, You can reinstall it and start to encounter "1372 ~ The drive letter is incorrect. Finally, it may be that the ODBC database file is damaged. Execute the "MSOWC" program in the office Installation File to fix the issue and install it properly. (Note: This Internet cafe is near the university. Office software is required to facilitate students)
