Hello everyone, Lin Fei to answer the above questions for you, cmos checksum error,cmos checksum error many people do not know, now let's take a look at it!

Computer is an indispensable part of our life and work, and we can do many things with it. In the process of using computers, we often encounter such a situation. One day we made good use of the computer, but the next day the computer suddenly appeared some errors or could not boot properly, resulting in the computer could not boot into the system, let alone work properly. Today, Bian Xiao summed up some common problems and solutions in which the computer can not boot into the system, mainly with "boot error prompt", "memory problem" and "graphics card problem" for everyone's reference.

1. Boot prompt "CMOS Battery failure"

The message means that the CMOS battery is dead, just replace the lithium battery on the motherboard.

two。 Boot prompt "CMOS checksum error-default value loaded"

Most of the reasons for this are caused by the power supply. Such as CMOS discharge after overclocking failure. CMOS settings should be saved immediately. If this problem occurs again, it is recommended to replace the lithium battery. If the battery replacement is still useless, send the motherboard for repair, as the CMOS chip may have been damaged.

3. Boot prompt "incorrect display switch setting"

This message indicates that the settings on the motherboard are not consistent with the BIOS settings, just determine which one is correct, and then change the wrong setting.

The problem is that an CMOSRAM checksum CRC error is found during power-on auto-detection.

The ways to eliminate this problem are as follows: 1. Restart the computer, display the startup message, press Delete to enter the BIOS settings, read the BIOS default settings, and then press F10 to save and exit the BIOS settings. two。 Start the computer again and the system is running normally, that is, troubleshoot the problem.

5. Boot prompt "hard disk installation"

Detect any hardware settings related to the hard drive, including power cables, data cables, and jumper settings for the hard drive. If it is a newly purchased high-capacity hard drive, check to see if the motherboard supports it. If there is no problem with all of the above, it is likely that there is a problem with the hardware, the IDE port or hard drive is damaged. Take it and fix it.

6. Boot prompt "hard drive diagnostics failed"

This message is usually a problem with the hard drive itself. You can connect the hard drive to another computer for detection. If the problem is not solved, it may be that the hard disk has a serious physical problem, such as zero track damage, which will be sent directly to the manufacturer for repair.

7. Boot prompt "Flooy disk failed"

Check any hardware settings related to the floppy drive, including floppy drive cables, power cables, etc. If all this is all right, it could be the floppy drive. Take it and fix it.

8. Boot prompt "memory test failed keyboard exists"

Check that the keyboard is connected correctly and reseat the keyboard to determine if the keyboard is good or bad.

9. Boot prompt "memory test failed"

Because of memory incompatibility or problems, each boot to plug in a separate memory test, to find out the problem of memory, reduce the memory utilization parameters and then run or send repair.

10. Boot prompt "override enable default value loaded"

This message usually appears when there is an error in BIOS settings. Just re-enter the BIOS settings, select the "LoadSetupDefaults" item, load the original default settings of the system, and then restart.

The computer cannot boot into the memory of a common system failure.

1. There is no display when the machine is turned on.

This problem is generally caused by poor contact between the memory stick and the memory slot on the motherboard. The problem can be solved by rubbing the golden finger with an eraser (don't clean it with alcohol, etc.) And this problem can also be caused by a damaged memory or a problem with the motherboard memory stick. Because of the memory stick, the boot does not show a problem, and the host loudspeaker usually rings for a long time.

The 2.Win registry is often destroyed for no reason, prompting the user to restore it.

Such problems are generally caused by the poor quality of memory sticks and are difficult to fix. The only way is to replace them.

3.Win usually enters safe mode automatically.

This problem is generally caused by the incompatibility between the motherboard and the memory bar or the poor quality of the memory bar. It is common to use high-frequency memory on motherboards that do not support high-frequency memory modules. You can try to slow down the memory read speed in the CMOS settings and see if you can solve the problem. Otherwise, you must replace the memory stick.

4. Random collision

This problem is generally due to the use of memory strips of several different chips, and the time difference of each memory strip leads to a crash. This can be solved by slowing down the memory speed in the CMOS setting, otherwise you can only use the same type of memory. Another possibility is that the memory stick is not compatible with the motherboard, which is generally rare. In addition, it is also possible that the bad contact between the memory stick and the motherboard leads to a random computer crash.

5. As memory increases, system resources decrease.

This phenomenon is generally caused by incompatibility between motherboard and memory. It is common to use high-frequency memory chips on motherboards that do not support this frequency. When this problem occurs, you can try setting the memory speed to a lower level in COMS.

6. When running some software, there is often a prompt that there is not enough memory.

This phenomenon is generally due to

This kind of problem is generally due to the fact that the user has added the emm386.exe file to the config.sys file, and the problem can be solved by blocking it.

The graphics card that the computer can't boot into the common faults of the system.

1. Display the fancy screen and can't see the handwriting clearly

Such problems are generally caused by the fact that the monitor or video card does not support high resolution. When the screen is blurred, you can switch the startup mode to safe mode, then enter the display setting under Win 98 and click the "use" and "OK" buttons in the 16-color state. Restart, delete the video card driver in the normal mode of the Win 98 system and restart the computer.

Such problems are generally caused by the following reasons:

1. Poor contact between display card and display signal line

two。 Problems with the monitor itself

3. Video card damage

4. The display is magnetized, this kind of phenomenon is generally caused by being too close to the object with magnetic properties, and the magnetization may also cause the display screen to deflect.

3. Abnormal spots or patterns appear on the screen

Such problems are generally caused by problems with the video memory of the video card or poor contact between the video card and the motherboard. The gold finger of the video card needs to be cleaned or the video card needs to be replaced.

4. Video card driver lost

The driver of the video card is loaded, and the driver is lost automatically after running for a period of time. This kind of problem is generally due to the poor quality of the video card or the incompatibility between the video card and the motherboard, which makes the temperature of the video card too high, resulting in unstable operation of the system or a crash. The only way to do this is to replace the video card. In addition, there is a special case in which the video card driver can be loaded before, but the panic occurs when entering the Win after the video card driver is loaded. Can replace other types of graphics card after loading its driver, insert the old video card to deal with. If you can not solve this kind of problem, then explain the registry problem, restore the registry or reinstall the operating system.

5. Crash

Such problems are generally seen in the incompatibility between the motherboard and the graphics card or the poor contact between the motherboard and the graphics card; the incompatibility between the graphics card and other expansion cards will also cause a panic. At this point, reseat the video card or replace the video card that matches its motherboard.

The above is about the computer boot can not enter the system of common failures and solutions in detail, I believe we have learned it! If you encounter similar problems, you might as well follow the above method. I hope the sharing of this article will be helpful to everyone!
