The computer automatically starts from 30, and the computer automatically starts from the beginning

Poor heat dissipation] The monitor, power supply, and CPU generate a lot of heat during operation, so it is important to maintain good ventilation, if the monitor overheats, it will lead to color, image distortion and even shorten the life of the monitor. Working too long can also cause the power supply or monitor to dissipate heat poorly, causing the computer to crash. CPU heat dissipation is an important issue related to the stability of computer operation, and it is also the "hardest hit area" where heat dissipation failures occur.

Device mismatch] If the main frequency of the motherboard and the CPU clock do not match, if the external frequency is set too high when the old motherboard is overclocked, the stability of the operation may not be guaranteed, resulting in frequent crashes. 【Software and hardware incompatibility】 Three-dimensional software and some special software may not be able to start or even install normally on some microcomputers, which may have problems with software and hardware compatibility. [Memory module failure] is mainly caused by loose memory modules, virtual soldering, or the quality of the memory chip itself.

Memory module contact faults should be eliminated on a case-by-case basis, and if there is a problem with the quality of the memory module, the memory needs to be replaced to resolve the issue. 【Hard Disk Failure】 It is mainly due to the aging of the hard disk or the bad sectors caused by improper use. In this way, the machine is prone to crash while it is running.

You can use special tools and software to troubleshoot, if the damage is serious, you can only replace the hard disk. In addition, for motherboards that do not support UDMA 66 100, you should pay attention to the setting of the hard disk operation mode in CMOS. [Hardware Resource Conflict] is an abnormal error caused by a conflict in the settings of the sound card or graphics card.

In addition, interruptions from other devices, DMA, or port conflicts may cause a few drivers to panic. The solution is to start in "Safe Mode" and make appropriate adjustments in "Control Panel" "System" "Device Management". For abnormal errors in the driver, you can go to the registry, find and delete all the "primary keys" and "key values" related to the driver prefix string through the "Find" function under the menu, and restart.

Memory capacity is not enough] The larger the memory capacity, the better, should not be less than the capacity of the hard disk, if there is a problem in this regard, you should replace it with a memory module with the largest capacity possible. 【Inferior parts】 A small number of unscrupulous businessmen use low-quality boards and memory when assembling compatible machines for customers, and some even counterfeit motherboards and remarked CPUs and memory, such machines are very unstable when running, and crashes are inevitable. Therefore, users should be vigilant when buying a machine, and can use some newer tools and software to test the computer, take the test for a long time (such as 72 hours), and strive for the longest possible warranty time.

See if the motherboard has a capacitor that is pulled up and the bulging capacitor is a bad pull It is recommended to go to a repair shop to put it back on is generally a motherboard problem.

Your virtual machine has a serious conflict with the system.

Memory conflicts, swap with memory sticks.
