4. Computer random crash
Mainly as a result of the adoption of different chips of memory, the speed of memory differences a time lead to the crash, this can be solved in the CMOS setup by reducing the memory speed, otherwise, can only use the same memory. Another possibility is memory do not compatible with the mainboard,this rarely happens. poor contact also might lead to random crash.
