Hello everyone, in this lesson we will introduce the file code failure

2

00:00:04,700 --> 00:00:08,933

The file code failure means that after the hard boot of the mainboard,

3

00:00:09,433 --> 00:00:15,133

an error is detected during the soft boot self-test running code, and the self-test program is stuck.

4

00:00:16,700 --> 00:00:22,966

Its fault phenomenon is that after pressing the switch, the code of the diagnostic card can run,

5

00:00:23,300 --> 00:00:28,166

but after running a few times, it freezes, and the mainboard will not boot.

6

00:00:29,566 --> 00:00:31,466

This is called blocking code fault

7

00:00:31,933 --> 00:00:35,366

There are many possible reasons for file code failure

8

00:00:35,566 --> 00:00:40,266

Most of the components on the mainboard can cause file code failure

9

00:00:40,666 --> 00:00:48,900

Such as CPU, bridge, memory, IO, network card, sound card, etc.

10

00:00:49,066 --> 00:00:55,133

Because the mainboard needs to detect these components during the code running self-test process.

11

00:00:55,266 --> 00:00:57,933

When there is something wrong with these parts,

12

00:00:58,200 --> 00:01:02,566

the self-test program will get stuck there, causing a file code failure

13

00:01:03,200 --> 00:01:09,166

Therefore, file code faults are generally more difficult to repair, because its fault range is too wide

14

00:01:09,666 --> 00:01:16,666

If we want to repair the file code failure, we must first understand the self-test process of the mainboard

15

00:01:17,100 --> 00:01:23,566

At the same time, it is necessary to use the diagnostic card to have a general maintenance idea.
