My computer is a VISTS system·· It used to be XP, and it seems that after changing the system, it will crash as soon as it is restarted?? Classmates told me it was a problem with the motherboard? I'm an ASUS M2A-MX motherboard.

Generally, the computer crashes with the hotkey method, that is, press the rset key, that is, the restart key, it is next to the boot button, and the notebook can only install the boot button for 7---10 seconds, of course, this method, desktop computers can also be used. Here's how to analyze the causes of the crash and how to deal with it:

To say that the computer crashes, there are many reasons for the computer crash, the first is that there is a problem with the power supply, such as the high-voltage rectifier filter circuit of the power supply, and the three-way switch tube has a problem, it will crash, the way is to replace the power supply, the second is the problem of memory and graphics card, such as the problem of the chip of the video memory and graphics card, resulting in a crash, The solution is to dial out the memory and video memory, Be sure to remember the direction, and then use the eraser to aim at the gold finger (that is, the part with the copper sheet) and rub it back and forth a few times. Then change a slot and plug it back, (don't change the graphics card) it's OK, the third is that there is a problem with the CPU, and there will also be a crash, (such as a broken fan) This is because the CPU temperature is too high and cannot be cooled down to cause a crash. The method is to clean up the dust, or change a fan, and the fourth is that if there is a problem with the motherboard, there will also be a crash, and there are many crashes on the motherboard. The fifth is that there is a problem with the computer's operating system, such as poisoning, loss of files, etc., and it is OK to reinstall the system.

Second: press alt+f4

Third: press Ctrl+Alt+The fourth type of task activity process that does not respond to ending from the task manager: ctrl+esc (generally useless).

Remember to disconnect the power supply before proceeding with the process.

1. Clean up the dust first, and wipe it off with a damp cloth (not too wet) or sweep it off with a broom after the power is off.

2. Use a hair dryer to blow the main engine and blow off the moisture.

Next, you can try unplugging the graphics card (if it's a discrete graphics card) and gently rubbing the gold finger with the eraser. Then Ann went back.

Finally, plug it in and try to start your computer. If that doesn't work (in the case of keyboard lights, mouse lights, and hard drives), try replacing it with another monitor.
