Win7 startup blue screen problem solution Windows 7 is Supply contracts referencing HS codesa popular operating system launched by Microsoft, which is widely used in personal computers, enterprise computers, school computer rooms and other fields. He. However, sometimes we will encounter a blue screen problem when we start up, which will cause us a lot of trouble when using the computer. So how to deal with the blue screen problem of Win7 startup? In this article, I will introduce several commonly used solutions to you. I. The first step to check hardware problems is to properly check hardware problems. Because in some cases, the problem of blue screen when power-on can be caused by hardware failure. Therefore, we can check whether the motherboard, memory stick, hard disk and other hardware equipment are in bad contact or damaged, and repair it.When checking, we can first try to remove the memory stick and reinstall it, which often solves the blue screen problem caused by memory damage. If this does not solve the problem, we can also try to replace the hard disk or add the hard disk to another computer to check for faults. II. The second step to upgrade the driver is to try to upgrade the driver installed in the computer. In many cases, the Windows drivers on the computer may not be updated in time, resulting in blue screen problems. We can run the device manager (in the control panel) on the computer, get the driver that needs to be upgraded, or download the corresponding driver and install it. After this operation, many driver programs have been updated successfully, and the blue screen problem will not reappear. III. The third step of repairing system files is to solve the problem by repairing the system files on the computer.When using Win7, if some file damage problems occur, some programs may cause a blue screen problem because they cannot access the relevant files. In order to solve this problem, we can search and run the "Command Prompt" in the "Start" menu of the computer, enter the sfc /scannow command in the command line and run it. This command will check the system files and automatically fix them when the problem is found. IV. If the above methods cannot solve the blue screen problem by using Windows recovery mode, we can try to use Windows recovery mode to fix it. Usually, we need to prepare a Windows installation disk or PE boot disk, and press F2 or DEL to enter the BIOS interface when the computer is turned on, and the boot device is set up.Set it as an optical drive or mobile hard disk, and then enter the Windows recovery mode to select the corresponding recovery options, such as system restore, repair startup, safe mode, etc. In Windows recovery mode, we can use system restoration to restore the Windows system to the state of a specified date, and we can also perform Windows file backup, backup registry and other operations. To sum up, the emergence of the blue screen problem of Win7 startup is largely related to the hardware, drivers, system files and other problems of the computer. By properly checking hardware problems, upgrading drivers, repairing system files and other methods, most blue screen problems may be solved. But if none of the above methods can solve the problem, we can try to use Windows recovery mode to solve the problem.
