When the computer boots to the Verifying DMI Pool Data solution: DMI is the abbreviation of the English word "Desktop Management Interface", which is the desktop management interface, which contains configuration information about the system hardware. The DMI data is verified every time the computer starts. If the data is wrong or the hardware changes, the machine will be detected and the test data will be written to the BIOS chip for storage. Therefore, if we disable the BIOS chip refresh function in the BIOS setup or disable the BIOS chip refresh function on the motherboard, the DMI data of this machine will not be updated. If you change the hardware configuration, then when you are running the WINDOWS system, the machine still works according to the old system configuration. This will not fully exploit the performance of the newly added hardware, and sometimes there will be failures of one kind or another. If we see this information when we start the computer, the system will stop for a long time or be in a crash state. It is generally difficult to handle such a fault. Because it can't be like the fault that occurs after entering the system, we can check the files such as the system log for analysis. However, according to the analysis of the process principle of PC startup, there are generally the following possible situations when this message appears: 1. Hardware changes When the hardware configuration of the host changes, but when we use the POST function, the system cannot recognize the system at this time. The newly added hardware will work according to the old configuration. At this time, it will be able to power up after booting, but there is no sound when the device is normally started. At the same time, the display has no image display, only the sound of the fan is rotating. . Another reason is that the compatibility of the newly added hardware is not good, resulting in the above situation. 2. BIOS setting changes When the BIOS settings are incorrect, such as incorrect read and write parameters of the memory, the mode setting of the hard disk is incorrect, the settings of the onboard sound card and the integrated sound card are incorrect, etc., which will cause the booting to fail. 3. The hard disk cable connection error. In this case, the data cable of the hard disk is in poor contact, the data cable quality is poor, and the data is lost incorrectly. The data cable is incorrectly plugged in (the motherboard is connected to the hard disk and the hard disk is inverted). The hard disk jumper is incorrect, the hard disk capacity or mode setting is incorrect. 4. The content of the main boot area of the hard disk is destroyed. When the content of the main boot area of the hard disk is overwritten by other programs or destroyed by viruses, the hard disk partition table may be cleared or artificially set to a logical lock state. . For the boot program of the main boot area of the hard disk is destroyed, we can use the Fdisk/MBR command to repair, or use the disk editing function of KV3000 to find out if the other 62 sectors on the 0th 0 side have the backup main boot area program, It can be restored to 0 0 0 area 0. It is more troublesome for the partition table to be destroyed. If only the partition table does not have the "80" or "multiple" flag, or the "55AA" flag, we only need to use the KV3000 disk editing function for manual repair. If it is a logical lock, you need to make a special disk to unlock. If the partition table is completely destroyed or encrypted, then we can only repartition. 5. The hard disk is faulty Now the capacity of the hard disk is getting bigger and bigger, and the speed is getting faster and faster, but the quality of the hard disk seems to be getting worse. Up to now, there are still hundreds of M used second-hand hard drives produced in the 94, 95 years. But now, just bought a new hard drive, in a few days, it will be bad or bad, and the data will not be lost. It’s not a matter of 咣咣 咣咣 rd rd 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢 罢When the hard disk hardware fails, the above situation will also occur. Such a problem can recognize the hard disk in CMOS, and the disk is very smooth, but it cannot enter the system and cannot be partitioned and formatted normally. 6. The motherboard has problems related to the motherboard and mainly the hard disk controller of the motherboard, resulting in unstable data transmission and high error rate. 7. Damage caused by overclocking If we overclock, we will also crash after booting to the hard disk. At this time, we should better remember the frequency of the CPU displayed during the power-on self-test, and then open the chassis to check the actual CPU frequency, whether the two are the same. Especially for CPUs after PIV, the integration is extremely high. If we use overclocking, it is very likely that the internal electronics of the CPU will be excessively attenuated in a short time, causing the CPU to be scrapped in a short time. Solution: 1. Restore the state before the hardware change and check if the system can start normally. 2. Check that all cables or expansion cards are properly connected. 3. Try to reconfigure in the BIOS "PNP/PCI configuration", "Reset Configuration Data"; you can also use the BIOS option such as "Force Update ESCD" to set to "Enabled", and then save and exit. If you can't start, try setting it to “Disabled”try it. 4. Check the motherboard manual for information on CMOS jumpers and clear CMOS. Please note: When clearing the CMOS settings, you must unplug the mains power cord or set the mains power switch to off or 0. 5. Disconnect the hard drive cable, including the optical drive or other IDE device, and then enter the BIOS setup to select the boot sequence as a floppy disk. After booting, press F10 to store and exit, then put a bootable system disk in the floppy drive to check if the system can start normally. 6. After clearing the CMOS settings, set the “PNP/PCI configuration” option in the CMOS settings to “Enabled”, and restart the computer to update the DMI data, also called the forced update of the ESCD data. 7. If the host can boot from the floppy disk, but it cannot be booted through the hard disk, the situation may be that the data of the main boot area of the hard disk is destroyed. At this time, the program code of the main boot area can be repaired by the partition software, such as booting with a floppy disk. After the computer, use the FDISK/MBR command to repair the main boot area. You can also download the special hard disk analysis tool program from the website of the corresponding hard disk manufacturer to check the specific fault of your hard disk. 8. If the fault cannot be eliminated after the above settings, then the problem of the IDE interface of the motherboard or the hard disk should be considered, which can be solved by the replacement method.
