5) Poisoning

6) Slow reaction

7) cannot enter the table

8) Missing files do not start

3. maintenance of crash

1).cpu fan is short of lubricating oil

2).CPU lacks thermal grease or is dirty

3).CPU fan with Lu Master test temperature pressure test CPU fan bad or slow rotation

4). Memory irregular crash

8. Hard disk failure

1) Ctrl+alt+del partition is not active or hard drive is not recognized

Reboot and Select Proper Boot device or Insert Boot Media in Selected Boot device and press a key

3) The sound of the hard disk appears, and the bad track appears. Use mhdd to detect it.

4) Hard disk not read

And common bios boot prompt failure

CMOS battery failed.

Reason: Description CMOS battery power is insufficient, please replace a new battery.

CMOS check sum error-Defaults loaded (CMOS checks all errors and loads preset system settings).

Reason: This situation usually occurs because the battery power is insufficient, so it is advisable to try changing the battery first. If the problem still exists, it means that CMOS RAM may have problems, and it is best to return it to the original factory for processing.

Display switch is set incorrectly.

Cause: older motherboard jumpers can be set to monochrome or color display, and this error indicates that the motherboard settings and BIOS settings are inconsistent, reset.

Press ESC to skip memory test.

Reason: If the Quick Power On Self Test is not set in the BIOS, then the boot will perform the memory test. If you don't want to wait, press the ESC key to skip or open the Quick Power On Self Test in the BIOS.

HARD DISK initializing【Please wait a moment...】Please wait a moment while the hard disk initializes.

Cause: This problem is not seen at all on newer hard drives. But on older hard drives, it starts slowly, so this problem occurs.

HARD DISK INSTALL FAILURE.

Cause: The power cable and data cable of the hard disk may not be connected properly or the hard disk jumper may not be correct (for example, two hard disks on one data cable are set to Master or Slave.)

Secondary slave hard fail.

Cause: 1 CMOS settings are improper (for example, there is no slave disk but there is a slave disk in CMOS) 2 The power cable and data cable of the hard disk may not be connected well or the jumper of the hard disk may be improperly set.

Hard disk(s) diagnosis fail.

Cause: This usually represents a failure of the hard drive itself. You can connect the hard disk to another computer and try it first. If the problem is the same, you have to send it for repair.

Floppy Disk(s) fail or Floppy Disk(s) fail(80) or Floppy Disk(s) fail(40)

Cause: Is the floppy drive cable connected incorrectly or loose? Is the power cord connected properly? If that's all right, buy a new one.

Keyboard error or no keyboard present

Reason: Is the keyboard cable plugged in? Is the cable damaged?

Memory test fail

Cause: Usually caused by memory incompatibility or failure.

Override enable-Defaults loaded (current CMOS settings fail to boot the system, BIOS defaults are loaded to boot the system).

Reason: It may be that your BIOS settings are not suitable for your computer (like your memory can only run 100MHz but you let it run 133MHz ), then enter the BIOS settings to readjust.

Press TAB to show POST screen

Reason: Some OEMs will replace the BIOS default boot screen with their own designed display screen, and this prompt is to tell users that they can press TAB to switch between the manufacturer's custom screen and the BIOS default boot screen.

Resuming from disk, Press TAB to show POST screen

Reason: Some motherboard BIOS provides Suspend to disk(suspend to disk) function, when the user suspends to disk to shut down, then the next time the boot will display this prompt message.

BIOS ROM checksum error-System halted(BIOS program code found an error during checksum, so it could not boot)

Cause: Encounter this problem is usually caused by incomplete BIOS program code update, the solution is to re-write the motherboard BIOS burned.
