Computer crash Solution

Every person who has used a computer may have experienced crashes. computer crashes are really annoying and sometimes cause a lot of losses to you, however, this problem is indeed very complicated. The crash may be a disadvantage on the hardware, a bug in the software, or, of course, your "illegal operations ". The following is an example of how to analyze specific issues:
Graphics card reason

Q: A computer Often crashes. When a computer is started, there will be three alarms. Sometimes the monitor cannot be lit, but the host works normally. After being set to 32-bit color, the host crashes more frequently. Why?

A: There may be two reasons for the above situation to crash: one is the abnormal working caused by poor heat dissipation of the display card, and the other is the poor compatibility between the video card and the motherboard. When the video card is set to a high color, it is likely that the display function of the video card is relatively weak. In the case of a higher color, the original resolution cannot be guaranteed. It seems that this problem is mainly caused by the video card.

Power supply reason

Q: The computer has always been in good use, but occasionally crashes during startup in recent times, not every time. Sometimes it takes two or three times to start smoothly. Why?

A: Since the previous usage has been very good, it is generally possible to eliminate the compatibility problem on the hardware, and the screen does not provide the relevant information when the machine crashes during startup, so it is not very like a software problem, so the most likely cause is the aging or overload of the power supply, generally change the power supply to check it.

Driver reason

Q: When Windows 98 is upgraded, the following message is displayed: "press start now to restart the computer immediately. Otherwise, the computer will automatically restart after 15 seconds ." Dialog box, but after the startup, the blue screen crashes. Why?

A: because it is A crash in the installation system, most of it is caused by A conflict of hardware devices. You can first unplug the extension plug-in card other than the video card, and then reinstall Win 98, if the above problem persists, it may be caused by the incompatibility between the Windows 98 System and the driver of the original video card. You can choose to enter the safe mode when starting the system, then, upgrade the driver of the video card in the control panel.

DOS Startup reason

Q: When the "Starting Windows 98" message appears after the computer is started, it crashes. Why?

A: In this case, the crash is probably caused by damage to the DOS Startup part of Win 98, because it has not yet entered the Win 98 system, to solve this problem, we need to use the boot floppy disk of Win 98. After restarting the computer with the boot disk, enter the "sys c:" command in DOS status, in this way, the DOS boot system in the hard disk can be solved. However, it must be noted that the boot disk must be consistent with the current operating system version; otherwise, the Windows system will be damaged.

Reason for Virtual Memory

Q: When a large application is running under Win 9x, the hard drive lights will flash, and the system will crash. Why?

A: This is A type of crashes that we often encounter. Most of these problems are related to the configured virtual memory. If the memory itself is relatively small and a large application is running, a large virtual memory is required. However, if the virtual memory is insufficient, this will cause the above crash. Therefore, it is recommended that you set the virtual memory size to a little larger and delete temporary virtual files frequently.

Registry reason

Q: Windows 9x registry crashes. How can this problem be solved?

A: The registry in Windows is very dangerous. Generally, do not modify it. If you have accidentally deleted the data, you can restore the backup registry. The specific method is to start the computer to the pure DOS state, and then enter the Windows directory, execute the command:

Attrib-h-r-s system. da0

Atttib-h-r-s user. da0

Copy system. da0 system. dat

Copy user. da0 user. dat

Finally, restart the computer.

Bootstrap cause

Q: After the self-check is enabled, the computer displays "No ROM Basic, System Halted" Information on the screen, and the hard disk will not flash any more. Why?

A: The cause of this fault is that the boot program of the hard disk is damaged or infected by viruses. It may also be that the last two bytes of the Master Boot area, "55AAH", have been rewritten, once the two bytes are rewritten, the system will no longer consider that there is a hard disk, so the operating system will not be able to start. The solution is to start the computer with a floppy disk and execute the "FDISK/MMR" command in the DOS state, so that the correct primary boot program and ending ID can be overwritten in the primary boot area of the hard disk.

Operating system installation reason

Q: When the computer is started, information about "Error Loading Operation System" is displayed on the screen, and the System crashes. Why?

A: The preceding information indicates an error occurred while loading the operating system. This prompt is displayed only when an error occurs while reading the Boot Sector of the partition. It may be because:

1. The partition start address indicated by the partition table is incorrect.

2. The track sign and sector ID of the track where the partition guide sector is located are damaged. The specified sector cannot be found.

3. The read circuit of the drive is faulty, but this is rare. Most of the errors are random read errors. Because the system boot has properly read a primary Boot Sector.

To solve the above problems, we need to use repair software such as Norton's disk doctor NDD to reply to the partition table of the hard disk.
