故障原因
上述電腦主板的故障類型，對(duì)系統(tǒng)的正常運(yùn)行造成極大影響，主板作為電腦主機(jī)的核心部件，能夠?qū)е律鲜龉收犀F(xiàn)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(gè)方面。 [5] 
人為因素
電腦本身就是為用戶休閑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(guò)程中，由于其本身的非專業(yè)性，導(dǎo)致經(jīng)常性的不規(guī)范操作現(xiàn)象，從而導(dǎo)致主板性能下降，造成主板故障。例如，在安裝設(shè)備時(shí)，安裝位置錯(cuò)誤或與主板及其他相關(guān)元器件接觸等，都會(huì)在程度上引起主板故障。 [5] 
環(huán)境因素
在主板運(yùn)行或儲(chǔ)存時(shí)，由于外界環(huán)境的影響，主板性能也會(huì)發(fā)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(wěn)的情況下，引發(fā)主板故障，屬于一種不可抗拒因素；其二，由于主板所處環(huán)境溫度、靜電、灰塵、濕度等原因，導(dǎo)致主板芯片在運(yùn)行時(shí)被損壞 [5]  。
