. I have a computer. Since the partition reinstalls the system (XP), when I turn it on every day, press the power button, the status light flashes, it seems to be started. Sound, then there is no reaction, press any button (except the power button) does not respond. The status light has 2 lights all the time. They are the power light and the horizontal N light. Press the power button again, only press for 1 second. The power light is off. The machine resumes the shutdown state. Press the power button again to start the machine, the machine starts normally. What is going on?
There is no response, it is I don’t feel very anxious, especially for a friend who can’t leave the computer all day, the computer is out of fault just like the one that lost something important, and the fault of booting without display is often encountered by everyone. The following three examples are used to analyze the causes and solutions of the three types of faults:
[Example 1]: The motherboard does not start, there is no display at boot, there is a video card alarm sound (one long and two short beeps)
The cause of the fault : This happens, usually the graphics card is loose or the graphics card is damaged.
Remedy: Open the chassis and re-insert the graphics card. Check if there is any small foreign object in the AGP slot, otherwise the graphics card will not be plugged into the position; for the motherboard using the voice alarm, carefully discern the contents of the voice prompt, and then solve the corresponding fault according to the content.
If the above method still handles the alarm, it may be that the chip of the graphics card is broken, and the graphics card is replaced or repaired. If you hear a self-test of "嘀" after booting, the monitor is normal but there is no image. Insert the graphics card on other motherboards. Normally, the graphics card is not compatible with the motherboard, and the graphics card should be replaced.
[Example 2]: The temperature control of the motherboard is abnormal, resulting in no display at boot.
The ASUS P3B-F motherboard can monitor the CPU temperature. With a 2Pin temperature monitoring line, the JTP pin is inserted next to the CPU slot. on. Later, during a game play, the machine suddenly blue screen, after restarting, after the CD-ROM drive and hard disk self-test, the display does not light up. Why is this happening?
The cause of the failure: The temperature control line connected to the motherboard falls off and falls on the motherboard, causing the motherboard to automatically enter the protection state and refuse to power up. Since the CPU is now very hot, many motherboards offer strict temperature monitoring and protection. Generally, if the CPU temperature is too high, or the temperature monitoring system on the motherboard fails, the motherboard will automatically enter the protection state. Refuse to power up, or alert you.
Remedy: Reconnect the temperature monitoring line and turn it on again. Note that when your motherboard does not start properly or alarm, you should first check if the temperature monitoring device of the motherboard is normal.
[Example 3]: The motherboard does not start, there is no display at boot, there is a memory alarm sound ("嘀嘀"called non-stop)
Fault reason: memory alarm fault is more common, mainly memory contact Caused by bad. For example, the memory stick is not standardized, and the memory stick is a little thin. When the memory is inserted into the memory slot, there is a certain gap; the gold finger process of the memory stick is poor, the surface of the gold finger is poorly plated, and the time is long, the oxide layer on the surface of the gold finger Gradually thickening, resulting in poor memory contact; the quality of the memory slot is inferior, the contact between the reed and the gold finger of the memory stick is not real and so on.
Remedy: Open the case, use the rubber to carefully clean the gold finger of the memory stick, remove the memory stick and re-insert it, fill the gap between the two sides of the memory slot with hot melt glue to prevent it from being used. Continue to oxidize. Note: When unplugging the memory module, be sure to unplug the main unit to prevent accidental burning of the memory.
The above three kinds of computer failures are very effective for solving the problem that the common computer has no display, but it is only limited to the occurrence of these three situations, and the occurrence of computer failures is various, if you still There are other problems to be solved, and we welcome everyone to discuss and study together.
