Fault instance
A MVP4 motherboard, K6-2 300 CPU, memory, 128M kuyu second generation 30G hard disk drive, floppy drive, there's no overclocking using compatible, appear random start bland, failed power-on-time performance is sometimes the normal post correctly, but often appears on a black screen.
Analysis and solution: I took over the machine, turn on after the performance to a black screen with memory error continuous chirping, suspected memory loose, open the case, see built-in two memory slots to plug in two root 64M of HY memory memory take down cleaned, reinstall the boot failure after disappearing, replace the computer restart, but there is no alarm black screen. It will also open the case, to take down a piece of memory, then another memory plug, press repeatedly and successive power, computers are good, they also turned off the chassis back installed on the computer, using all normal. But the next day the user to the phone, computer and black screen. The computer is moved to the us look, again to reinstall the memory and put on the new memory, the strange computer actually no alarm sound and the sound post. First with minimum system method to open the hard drive, optical drives, sound cards, etc, leaving only the motherboard, CPU, memory, video card, minimal system remains a black screen, then use the change method a try, this machine parts are normal, back in the machine, installed the smallest system again to turn the computer back to normal. First ruled out within a short, focused on suspected there was a problem with the memory slot and the CMOS battery voltage low, in line with the principle of increasing difficulty of maintenance, removing the CMOS battery avometer discussion about many 3.03v took a new CMOS battery on the left and right, old battery 3.35v electricity slightly less than, the replacement of the replacement installed machine, not on the hard drive continuous switching machines, no more random bland. Thought that the story itself, the second day of the user to pick up the computer, turn on the host fan are functioning, but no sound the alarm sound, post, display a black screen again and no screen display and a number of time the player is not able to resolve the issue, feel very strange, suspected computer Board or motherboard and components are bad, or components soldered, key check Remove the motherboard, motherboard carefully observe their components and no obvious signs of loosening, magnifying its backplane found CMOS chip solder joints, outlet has virtual welding signs, fetch a soldering iron to a welding (it is important to note that general users avoid do-it-yourself repair welding, unless you have very high welding technology, truthfully in find not to try on board power and a large component of suspicious conduct welding solder joints), failure to completely exclude them. In this case failed to clear components of welding quality caused by the fault, a normal user the best optional diagnostic card motherboard using "" detection tools on these hard to judge a site probably, more can be targeted.
III. system running bland
System running bland main can be divided into the hardware causes black screen, software, failure of a black screen and hardware incompatibility caused by some kind of a black screen. And the system running bland also often accompanied with panic phenomenon.
1. hardware causes
Hardware causes black or blue screen of death crash for accessories for quality, compatibility, physical damage. As we all know, the computer of all parts of quality problems, docking of interface is bad, the hardware device
Setup issues (such as BIOS and driver improvement issues, and system compatibility issues, hardware, power supply units of stability, resistance to outside interference problems), are likely to cause computer hardware black screen of death. Particularly poor memory or graphics quality is the main cause of such failure, we check for this kind of failure may first replace the video card memory, or to try, but for a different kind or type of memory the computer plug, first try to retain a single memory types. In addition, the motherboard and CPU, motherboard and video card compatibility issues are also worth your while to resolve these issues. In the installation and removal of hardware device black screen of death crash is also very common, it is usually and equipment installation unreasonable is not in place, electrostatic interference and device equipment/interrupt conflict-related, when setting up equipment, it's a good idea to check the equipment reservations interrupt (IRQ), do not let other device using the interrupt number reserved.
2. the software causes
The system is running in the bland, software causes than hardware class black screen of death phenomenon is more common. For example, the operating system itself of compatibility issues, the operating system and application software compatibility problem, system settings for your lost or damaged, the application software itself Bug issues, software settings, as well as software and software conflicts are likely to cause the system software causes black screen of death.
New and old versions of the Windows system software compatibility — such as a Windows version of the design are not perfect in itself and not likely to cause its compatibility is not good cause black screen of death, the old version of Win95/98 and Win2000/XP, and the new version of the application software and system or driver conflicts, particularly in Win98 and other operating systems use Win3.X in 16-bit application, it may result in 16-bit application software with Win98, etc is not compatible with 32-bit operating system.
System and application software compatibility or damaged — Windows system software is corrupted or lost may cause panic fault, because the system startup is a step by step process, which is not an error if there is a corrupted file or driver, the system dead here. Of course some version of the Windows system or software, design ** or compatibility of imperfect can also cause system run time when the machine goes black.
Application software and application software compatibility — increasing the hard drive, install software today is too large, it may cause software and software "fight", the light is caused by normal use, you can make the computer a black screen of death. In addition, your computer is infected with a virus causing some file cannot normally use, of course, will result in a black screen of death crashWhile some instant kill/antivirus soft
Pieces are sometimes is computer frequently black screen of death.
In addition to Config.SYS, Win.INI, System.INI Auto execute .BAT, and so on system configuration files, such as no special needs, it may not be the system loads the extra data in the file.
In Win98/Me/XP, you can click the "start", then click "run". In the "open" box, type "msconfig", and then click "OK" to open the "system configuration utility" view or change the above system configuration file to load. If the Config.SYS and Auto Executive .bat file makes the system hook DOS real mode CD-ROM drivers, then easily black screen of death because in DOS real mode of State work CD-ROM read in operation requires BIOS provides a lower layer services program, and the Win98 above but uses its own 32-bit protected-mode drivers, they are very easy to create a conflict.
Fault instance
When you start your computer, the system displays "Invalid VxD" error message and a black screen of death.
Analysis and solution: first, if you have recently been removed from the computer programs or components, reinstall it, and then run the uninstall tool. If you can't find the program or component to uninstall tool, can be used with the vendor for the delete program or component.
If Vnetsup.vxd file is missing, you can install and then remove a network component that you can avoid this problem. And then double-click the "network" and click "add" and click the "adapter", and then click the "add".
In the "manufacturer" box, click the "detected network driver". In the "network adapter", click on "existing Ndis2 driver", and then click OK. Prompted to enter a group name and computer name, please fill in the "identification" tab of the corresponding box. Click "OK" or "off" until you return to the "Control Panel". You are prompted to restart your computer, click the "OK". After you restart your computer, double-click the "network". Click on "existing Ndis2 driver", click "delete", and then click OK. You are prompted to restart your computer, click the "OK".
-If an error message involving .386 file, you can disable the System.ini file in the device driver. To disable the device driver, click the "run" and type "msconfig", and then click OK.
In "System.ini" tab, double-click the "[386Enh]," positioning involves device driver line, click to clear the check box next to the row, and then click OK. You are prompted to restart your computer, click the "OK". If the error involves no extension of the file, the file may not be listed in this section, if the file is not listed in this section, you can select the following the "no".
— The StaticVxD value in the registry is correct and if the error message does not specify a device driver in the registry
StaticVxD value of an may be empty or contains only spaces.
StaticVxD value in the registry of the following items:
HKEY_LOCAL_MACHINE\System\CurrentControlSet
\Services\VxD。 To correct the registry for the StaticVxD
Values, you can back up the registry files, click the "run". In the "open" box, type "scanregw", and then click OK. Prompted to back up the system registry, please click "Yes", and then click OK. Use the "Registry Editor" to find and delete the registry contains invalid data, null data, or only the StaticVxD value containing spaces. Click "run". In the "open" box, type "regedit", and then click OK. In Registry Editor, expand the keys mentioned above. In the key of all child key in the lookup contains invalid data, null data, or only the StaticVxD value containing spaces. Right-click the entry, and then click the "delete".
If the system shutdown black screen of death, generally speaking, and system settings, power settings and stability, the stability of the hardware device and its driver installation and Setup, and so on all have a great relationship. Especially some application or driver settings or improper use, or in use error can cause a shutdown of the black screen of death, in the "Device Manager" in the back or the update installation some ** an exclamation point with conflicting device drivers, or try to uninstall some application a try.
