Reasons for black screen in win10
1. The optical drive is opened abnormally when reading a disk.
This phenomenon occurs when the optical drive is reading data and is opened by mistake, resulting in a black screen. This problem does not affect the normal operation of the system, just eject the CD or press the ESC key.
The above are several reasons that caused the black screen that I encountered during computer maintenance. There may be other inexplicable problems that cause the computer to have a black screen. In any case, when encountering this kind of problem, you should carefully analyze the cause of the problem before starting to solve it.
2. The remaining space of the hardware is too small or there are too many fragments.
Since Win9X needs to use the hard disk as virtual memory when running, this requires that the hard disk must retain a certain amount of free space to ensure the normal operation of the program. Generally speaking, the minimum space should be more than 100MB. Otherwise, the "black screen" may be related to the remaining space of the hard disk being too small. In addition, too many hard disk fragments can easily lead to a "black screen". Therefore, defragmentation every once in a while is necessary.
3. System hardware conflict
This phenomenon leads to "black screen" is also relatively common. What is often encountered in practice is the setting conflict of the sound card or display card. Check whether there is a device with a yellow question mark or exclamation mark in "Control Panel" → "System" → "Device Management". If it exists, try to delete it first and restart the computer. Win9X will automatically adjust it, which can generally solve the problem. question. If it still doesn't work, you can manually adjust or upgrade the corresponding driver.
4. The screen displays that the system is busy, please press any key to continue.
Insufficient virtual memory causes system multi-tasking errors
Virtual memory is a unique method of WINDOWS system to solve the problem of insufficient system resources. It generally requires that the remaining space of the hard disk in the main boot area is 2-3 times of its physical memory. In order to make full use of the space, some enthusiasts fill their hard drives to capacity and keep in mind the demanding requirements of WINDOWS. As a result, the virtual memory has an operation error due to insufficient hard disk space, so a black screen appears. To solve this problem is very simple, try not to fill up the hard disk, and frequently delete some temporary files and swap files generated by the system to free up space. Or you can manually configure the virtual memory, select Advanced, and transfer the default address of the virtual memory to another logical disk. This avoids black screens caused by insufficient virtual memory.
5. CPU overclocking causes calculation errors
Overclocking is a common thing for enthusiasts, so various failures caused by overclocking are inevitable. Overclocking itself is to achieve higher performance on the original basis, but due to overloading operations, too many internal operations are caused, causing the CPU to overheat, resulting in system operation errors. Some CPUs have better overclocking performance, such as INTEL's Celeron processor and AMD-K6-2 processor, which are relatively good, but sometimes some inexplicable errors may occur. (For example: I once tried to overclock the INTEL Celeron 300A to 450, and the floppy drive read the disk without accepting the command). The overclocking capabilities of INTEL's sub-200 CPUs and AMD-K5 are not that good. It is recommended that when a high-end CPU is overclocked, the heat dissipation work must be done well. It is best to install a large fan and some heat dissipation materials such as silica gel. As for some low-end CPUs, I suggest you not to overclock, otherwise the overclocking will not achieve the expected effect but will often cause a black screen and affect the normal speed of the computer.
6. Incompatible or damaged memory modules cause operation errors.
This is the most intuitive phenomenon, because this phenomenon can often be seen when the computer is turned on. The computer cannot be started at all. The screen prompts that there is a memory problem and asks you if you want to continue. This error is caused by physical damage to the memory or incompatibility between the memory and other hardware. At this time, the only option is to replace another memory.
