故障原因
上述電腦主板的故障類型，對係統的正常運行造成極大影響，主板作為電腦主機的核心部件，能夠導致上述故障現象的原因也是多種多樣的，主要的故障原因主要包括以下三個方面。 [5]
人為因素
電腦本身就是為用戶休閒與工作提供便捷的載體，用戶作為電腦的主要接觸者，在使用過程中，由於其本身的非專業性，導致經常性的不規範操作現象，從而導致主板性能下降，造成主板故障。例如，在安裝設備時，安裝位置錯誤或與主板及其他相關元器件接觸等，都會在程度上引起主板故障。 [5]
環境因素
在主板運行或儲存時，由於外界環境的影響，主板性能也會發生程度的變化，主要的故障原因可分為兩種：其一，在雷擊或供電不穩的情況下，引發主板故障，屬於一種不可抗拒因素；其二，由於主板所處環境溫度、靜電、灰塵、濕度等原因，導致主板芯片在運行時被損壞 [5] 。
