The solution to the blue screen problem of Windows system boot is that the error of mprexe file is a serious error, which can be caused by virus attack, hardware failure and software error. First, use the latest version of antivirus software to kill viruses. If it is non-toxic, please restart the computer, press F8 to select safe mode and enter the system to see if there is an error message of "mprexe file error". Then, pay attention to check the hardware in Device Manager for errors such as repetition, exclamation mark and red cross. If yes, delete and re-enter the system. Just follow the prompts to install the hardware driver. Sometimes, this kind of error will only appear because of poor contact of individual hardware. At this time, all the accessories need to be unplugged and plugged in again. Causes and solutions of "blue screen" of computers: In the process of using computers, blue screens are often encountered. For beginners, this is like a computer disaster, and they are at a loss. In fact, as long as you know the reason, don't be afraid. There are many reasons for the blue screen of the computer, which can be summarized as follows: 1. The screen shows that the system is busy, please press any key to continue ... 1. Insufficient virtual memory leads to system multitasking error. Virtual memory is a unique method to solve the shortage of system resources in WINDOWS system. Generally, the remaining space of hard disk in the main boot area is required to be 2-3 times of its physical memory. In order to make full use of space, some enthusiasts cram their hard disks full and are busy remembering the harsh requirements of WINDOWS. As a result, the virtual memory has an operation error due to insufficient hard disk space, and a blue screen appears. To solve this problem, it is very simple. Try not to fill the hard disk, and often 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 can avoid the blue screen caused by insufficient virtual memory. 2, CPU overclocking leads to operational errors overclocking is a common occurrence for enthusiasts, so various failures caused by overclocking are inevitable. Overclocking itself is to achieve higher performance on the original basis. However, due to overload operation, too many internal operations and overheating of CPU, the system runs incorrectly. Some CPU overclocking performance is better, such as Intel Celeron processor and AMD-K6-2 processor, but sometimes there are some inexplicable errors. (For example, I tried to read the Intel Celeron 300A when it was overclocked to 450, and the floppy drive didn't accept the command). CPU below Intel 200 and AMD-K5 have poor overclocking ability. It is suggested that when the high-grade CPU is overclocked, it is necessary to do a good job of heat dissipation, and it is best to install a large fan and add some heat dissipation materials such as silicone. As for some low-end CPU, I suggest that you don't overclock it, so as not to overclock it to achieve the expected effect, but often the blue screen will affect the normal speed of the computer. Second, the memory card is incompatible or damaged, resulting in operational errors. This is the most intuitive phenomenon, because you can often see this phenomenon when the computer is turned on, and the computer can't start at all. The screen prompts that there is something wrong with the memory, asking whether to continue. This error is caused by physical damage of memory or incompatibility of memory with other hardware. At this time, only another memory was changed. Third, the phenomenon of being attacked by unknown programs or viruses, as long as it is encountered when we are surfing the Internet at ordinary times, may expose our IP when we are surfing the Internet, especially when we enter some BBS stations, and be attacked by hackers with some software. In this case, it is best to install some defense software on your computer. Then log in to BBS to make security settings and hide your IP. 4. The abnormal startup of the CD-ROM drive when reading the disk is that the CD-ROM drive has a blue screen due to misoperation when reading data. This problem does not affect the normal operation of the system, just eject the CD or press ESC.
