What is the reason of computer screen flashing

Notebook computer screen flashing, boot when the most powerful, where is the bad? Sometimes flash a few seconds and it's okay, so what should we do when this happens?

In general, there are two possibilities, one is that the line is not connected or loose, the second is the screen inside the lamp is broken or bad contact, first demolition Machine Check whether the line is normal, if normal is the case of the lamp, this will take to professional maintenance point maintenance, this kind of lamp in the Internet or computer city are sold, If you have a better understanding of the notebook can also try to change their own, but to change the time must be careful to plug inside the accessories, and the size of the tube and the screen also has the corresponding model!

You can also check the next few:

The internal chassis temperature is too high, video card, memory, power--will cause blue screen, panic, the following is a personal experience in the maintenance of a summary of some of the experiences you can look at the Control check processing. ---you can check, clean, replace, memory, hard drive data cable first.

1. The memory strip touches some metals to produce oxidation, or uses two memory strips, one of which is damaged or incompatible. The independent video card contacts some metal to produce the oxidation, unplug the memory, the video card, the clean contact part metal (gold finger) replaces the damaged memory strip. Clear the video card heatsink, fan dust. If the fan is damaged and replaced.

2: Motherboard: After a certain period of time, the motherboard to accumulate a large amount of dust. Electrolytic capacitors produce leakage, blowing up, failure. Remove the motherboard dust thoroughly. The focus is on memory slots, video slots, and around the CPU. Replace the capacitor or send it to repair.

3:cpu. CPU is the highest commander of the computer, if there are problems, such as high temperature, voltage instability, excessive overclocking use, then the CPU will automatically protect itself. The computer will be paralyzed, so there will be blue screen, crash 、----clean CPU radiator, fan dust. Replace the thermal grease under the heatsink and restore the CPU default frequency.

4: Power, Power is the driving force for the normal work of the computer. The use of a certain period of time due to the accumulation of dust, capacitor failure, fan dust, speed down, resulting in poor heat, output power down, will also cause panic, restart, blue screen----repair or replace the power supply.

5 system drivers installed using the Ghost version are often not properly installed, especially for sound cards, network adapters, video cards, and motherboard chipset drivers. ----workaround, install the motherboard with the installation CD-ROM, download Everest view the exact model of each hardware, download the Driver Wizard, and then install the correct driver.

6: Hard disk or hard disk data cable problems, the hard disk with the use of time, the use of the abnormal shutdown in the process of logic or physical bad way. Logical bad ways can be repaired using proprietary software. Physical bad way can only replace the hard drive. Data cable If the use of time too long will be a problem, you can use the replacement method, (data line failure and memory failure shows a very similar phenomenon)
