Lenovo notebook Y40 Win7 system irregular crash reason and solution

phenomenon description: Lenovo notebook Y40 installed Win7 Ultimate system will occasionally crash, but the operation is not the same before each crash, how to Phenomenon analysis: This phenomenon can be understood as a random crash in the Win7 system. Random crash is a common fault that is often encountered during computer use. Due to the uncertainty of the failure of the crash, the nature of the operation is not fixed, and when the crash occurs, the displayed phenomenon is not uniform, so the scope of the fault is not easy to locate, which brings certain difficulties to the repair operation. Solution: The causes of random crashes are mainly the following three aspects. If it is not a random crash, you can check the common phenomenon of the Win7 system computer crash to check the paper. I. Environmental factors Random failures caused by environmental factors account for about 10% of the total number of failures. Environmental factors mainly include: temperature, humidity, grid interference, electromagnetic shock, external oscillation shock, static electricity, grounding system, power supply system, etc. The above mentioned are the factors that have the greatest impact on the normal operation of the machine. At the same time, due to the machine working environment such as dust, moisture, short circuit between the chips or poor contact between the plug and the pull, it may cause the occasional crash of the Lenovo notebook Y40Win7 system here. So keep your computer away from bad environments. Second, the software causes Random failure caused by software causes the failure of about 20% of the total number of failures. The Lenovo notebook Y40Win7 system caused by the software system crashes from time to time, that is, the random crash includes two situations: 1. Virus damage Although sometimes the computer can be started again by cold and hot start, but it will crash soon after running. 2. The application software is not fully compatible with the operating system. There is a conflict between them or conflicts with the inherent characteristics of the hardware. Most of these crashes do not have a keyboard response, and the computer can only be started again by a cold boot. For the random failure of the software, the method of checking for the failure is to use a clean boot disk to reboot the machine, and then run the anti-virus software to remove the virus. For application software and operating system conflicts, it is recommended to modify the program configuration and change the computer hardware configuration to solve. Third, the hardware reasons Random failure caused by hardware causes the failure of about 70% of the total number of failures, is the main cause of random crashes. The crash caused by the hardware system is mainly caused by the quality, compatibility or mismatch of internal components of the computer. Usually include: pluggable chip contact failure, poor thermal stability, chip mismatch, poor chip drive capability, poor anti-interference ability.
