Usually if there is a problem with the hardware system, the boot process is not smooth. Various types of hardware failures can be reported by the system as soon as you turn on the computer.
Error messages related to RAM memory
- 128 Not Ok, Parity Disable
This message appears when the RAM is faulty, or you have installed RAM with incompatible speed with your motherboard.
- RAM Test Address Failure
Error due to the damaged memory addressing chip, because these chips are integrated on the mainboard, so you must repair or replace the motherboard.
Error messages related to the keyboard
- 8024 Gate – A20 Error
Keyboard failures, often caused by key jams, cause the keyboard controller chip to signal continuously into the computer.
- Keyboard Stuck Key Failure (Keyboard Error)
Error due to damaged keyboard cord, or jammed keys.
- Keyboard error, press F2 to continue
This message appears when the system is active but the keyboard cannot be found. The solution is to remove the keyboard to check if any keys are stuck or not. If you use a keyboard with a USB port, but the port is not open, you must use a clipboard PS2. Then you go to CMOS, open the USB port and attach the USB keyboard to use.
Error messages related to hard disk
- Bad or Missing Command Interpreter
Error of not finding the operating system command file, but usually due to a damaged hard disk, resulting in unreadable files.
- Bad Partition Table
Error caused by the hard disk created and incorrectly partitioned.
- C: Drive Error
An error is caused by incorrectly declaring the hard disk parameters in CMOS.
- Disk Boot Error, Replace And Strike To Retry
Error because the computer cannot find the bootable disc.
- Disk Drive 0 Seek Failure
Error due to the data cable, or faulty control circuit of the drive.
- Disk Boot Failure
Error due to damaged boot disc, you need to replace another boot disk.
- Hard Disk Failure
The error is caused by one of the following reasons: the hard disk controller circuit is damaged, the power cord is not attached to the hard drive, the data cable is plugged in the wrong head, or the master / slave selected jumper is incorrect.
- File allocation table bad, drive X
There is a mismatch in the hard drive fat containing the boot information, for many reasons. The workaround is low-level format reinstalling Windows.
- General failure reading drive X
You check in the drives to see if there is a boot disk, otherwise the hard drive has a problem.Try shutting down and then restarting sometimes this error is reported when the machine is having trouble booting if you have luck in your system. you work normally again.
- Invalid frive specification or drive not ready
Common messages when something is wrong with the boot drive. Old drives tend to boot slowly and experience this error. The best way is to reformat the hard drive and reinstall the operating system.
Error messages related to CMOS
- Cmos Battery Stage Low
Error due to running out of battery clock and CMOS circuitry, can also be caused by incorrect CMOS erase pin jumper.
- Cmos Checksum Failure
The error indicates that the CMOS data is corrupted, possibly due to the out of battery supporting the clock circuit and CMOS.
- Cmos Display Type Mismatch
Error due to incorrect declaration of card displayed in CMOS.
- Cmos Memory Size Mismatch
Error due to damaged memory chips or unsecured RAM plug.
- Serial Port Test Failure
Error due to serial port and parallel port not responding to boot test (POST).
- Math Coprocessor Failure
Error caused by a malfunctioning math coprocessor.
A hard-to-handle hardware error at boot
During the boot process, the computer freezes and you get a fairly general message:
*** Hardware Malfunction
Call your hardware vendor for support
*** The system has halted ***
In addition, there may be some accompanying notices such as:
NMI: Parity Check / Memory Parity Error
NMI: Channel Check / IOCHK
NMI: Fail-safe timer
NMI: Bus Timeout
NMI: Software NMI generated
NMI: Eisa IOCHKERR board x
Most of the cause of the error lies in the motherboard, mainly related to the RAM memory, or the buffer memory on the motherboard or other motherboards.
To fix the error, you need to do the following three steps:
Please remove the new RAM sticks added to the computer, leaving only the old RAM sticks that the computer has previously successfully booted up. Then reboot to see if the above error message still appears. If the error goes away, you have solved the problem. Next you will proceed to isolate wading by each time adding a stick of RAM to the machine and restarting.
In addition, Microsoft also provides a tool to diagnose RAM errors called Windows Memory Diagnostic. This utility will help you check your computer’s memory and detect errors.
Check for additional expansion cards
In the next step, you will also experiment with expansion cards. Remove most of the existing expansion cards in your computer, and leave only the ones that are absolutely necessary, such as the video card.
If no errors are reported, then one of the expansion cards you removed has a problem with its memory. To determine correctly, you reinsert each card and when the error reappears when the card is inserted, that card needs to be removed from the system.
Check the BIOS configuration
If the RAM removal and expansion card process cannot determine the cause of the error, then the next thing to do is to check if the BIOS on your motherboard is up to date.
If the latest version is up to date, go to BIOS and select Fail-safe defaults or BIOS defaults. Also, turn off anti-virus function in BIOS, and switch Plug and Play OS entry status to No.
