硬件分析和常见故障处理（Hardware analysis and common troubleshooting） Computer crash phenomenon causes [poor ventilation] [mobile killer] [dust killer] [equipment mismatch] [hardware and software compatibility] [memory failure] hard disk failure [CPU overclocking] [hardware resources conflict] Insufficient memory capacity [inferior parts] [viral infection] [CMOS settings improperly] [system file deletion] [initialization file was destroyed] [dynamic link library file (DLL) lost] [hard disk space is too small or too many pieces] [BIOS upgrade failed] [software upgrade inappropriate [abuse of beta software] illegal uninstall software] use pirated software] [application software defects] Too many programs have been started [illegal * *] [abnormal shut down] [memory conflict] The correct installation of the hard disk The installation of hard disk is different from other parts, it is afraid of impact, vibration of vulnerable parts, so installation should pay attention to gently handle, in moving, also want to avoid strong vibration, lest damage Hard disk drives cause physical damage that can not be repaired.

If the power is suddenly cut off, the head and disk will be violently rubbed, which will lead to the friction between the head and the disk The hard disk has bad sectors and even damage.
