Computer failure maintenance related--rainy day white

first you need to know how to manage your own server and then have to know what to do with the machine. You also need to be able to spend a lot of time on the network, pay attention to the new information, to the Internet bar computer content to update Oh, yes, very important point: to know how to use technology to lazy, improve the management efficiency of the computer Internet cafes The first part: Computer fault maintenance Part One, the monitor black screen black screen is our computer startup often encountered problems, black screen is usually caused by the following reasons: 1, look at the monitor power on no, if open please check the monitor power cord connection is intact. Remember, if you do not first turn on the monitor power, will cause the black screen of the façade, don't forget oh ^_^. 2, such as the display power has been turned on, display power lamp display is normal, but the screen is not displayed, the reason may be the display brightness or contrast adjustment ratio is not appropriate, also does not exclude the video card hardware failure or the display signal line and the graphics card interface bad contact May. Second, the computer can not start the computer boot, the monitor power indicator is working properly, the computer may be powered up but unable to start. To solve the problem that the computer cannot start, it is recommended to use the replacement method. The so-called substitution method, the normal hardware, replace the faulty machine, if it can start normally, you can determine which hardware has failed. This fault is usually caused by the following reasons: 1, the computer host power damage, although the ability to boot, but can not start normally, please replace the power supply. 2, the motherboard COMs chip damage, especially by the CIH virus damage, the computer can not start normally. 3, the host power lamp is bright, no other alarm sound prompts, this may be the CPU damage or poor contact. 4, the host device itself without any problems, but the host can be power-up but not self-test, this may be the motherboard or CPU is overclocking, restore the BIOS default settings. If the CMOS jumper is not found on the motherboard, the battery on the motherboard can be removed directly and the positive and negative polarity will be shorted for 10 seconds. 5, the network card is damaged or contact is not good, also may cause the machine cannot start. 6, video card, memory and motherboard is not compatible, will also cause the machine can not be restartedMove. 7, the memory slot on the motherboard, the video card slot is damaged. 8, the memory of the gold finger rust, you can use the new renminbi rub the gold finger, and then plug into the machine can solve the problem. 9, the host has a lot of dust, resulting in poor computer accessories, recommended to use hair dryer or clean dust with hair rinse. Remember not to use compressed air pump to clean up the dust, because the compression pump work prone to water droplets, with the exhaust, attached to the motherboard, damage to computer accessories. Three, the machine can start normally, but unable to enter the operating system computer can normally start, the hardware all run normally, but the impermanence normal into the operating system work. The main fault phenomenon has the following methods: 1, the computer can start normally, the monitor enters the operating system desktop before normal, into the system desktop after the black screen. This fault is generally caused by the high resolution setting of the Monitor, please enter from the installation mode, remove the video card driver and re-enter it. 2, the computer can start normally, before entering the operating system to stop the boot error prompts, check the CMOS device startup settings or the boot sequence is incorrect. You will be prompted to find an interface device such as a disk or IDE. 3, the system starts, the prompt cannot find the hard disk. The hard drive power cable or data cable is not connected or is damaged. Reconnect or Replace. 4, the machine hard disk is working normally, error loading operating system prompt, please check whether the system partition is activated. If not, please re-use the partition software to activate the partition. 5, boot prompt hard disk I/O error, please check whether the hard disk is working properly. If the hard drive works, the hard drive has been installed with Restore Wizard-like restore software, and I/O protection is enabled. Please download the erase of the restoration software to clear the original hard disk partition table, or you can use the FDISK/MBR command to recover the hard disk partition table. Four, the machine can start normally, after entering the operating system for a long time no response or response slow 1, after entering the mouse cursor has, but cannot move, press the keypad number key (NumLock) no response. Please check whether the color of the display is 256 colors, because when using the Vientiane environment Billing software, when the color is 256 colors, the machine will not respond. After you disable billing software, change the display settings to normal. 2, the machine into the system all normal, work for a period of time will not respond, the mouse can not move, the keyboard did not respond. This is usually the motherboard CPU, near the power block of the local capacitance damage, observe, you can see the top of the capacitor cracks, or a light yellow liquid next to the imprinted presence. This is a hardware damage, please replace the motherboard. General small manufacturers of motherboards, using a recycled capacitance, often there will be a phenomenon of capacitor explosion. 3, the machine into the operating system is normal, when running a program, the crash, which is generally due to the graphics card driver version is not caused by the replacement of other versions of the driver can be resolved to askProblem. 4, the machine enters the operating system, the mouse keyboard has a reaction, after a long time before normal operation can be carried out. This may be too much to load the startup software in the computer startup item, and the auto-start setting can be canceled. If it is not loaded in the startup item, run the Msconfig command to check which programs are automatically loaded in the startup options and remove the unrelated autoloader.
