開機後一段時間鍵盤冇燈加冇反應

如題，過係bios interface 等一樣，約莫開機後1分半鐘斷電。唔入bios直開，快手打密碼都入到但冇幾耐一樣斷電，唔知咩事。

This most cause by:-

1. CPU overheat...
Check CPU heatsink mounting is tighten ?
Check CPU fan is running or not?

2. Memory bad contact, clean the gold finger with a pencil eraser

佢係啱啱開機分幾鐘的話應該唔係過熱
室溫 開機過熱 降頻到斷埋1-2分鐘太快啦

RAM有2條以上的話可以用單條試下試晒咁多條

然後標題同內文好似有D出入
鍵盤冇燈加冇反應<--咁講比人一種風扇仲轉仲有電到 當機既感覺
冇幾耐一樣斷電<---咁講係斷晒電風扇唔轉 供電問題斷埋電既感覺
其實係邊種

1. With a loosen heatsink (1 of the 4 leg broken due to ageing on Intel stock cooler) or CPU fan fail, the CPU temperature will rise rapidly cause CPU are running at maximum speed during start up, so shut down within few minutes is possible.

2. Ram bad contact might cause lot of symptoms

3. Defected USB device connected will affected the 5V output & cause keyboard not working.

4. I also experienced the same symptoms with a corrupted BIOS on X99 platform

1我有保留
樓主係開機幾次
過熱應該有第一次可以運行時間比較長既情況 樓主冇講
我所知有D唔用散熱都可以開機行到(但有風險勿試)
同就咁放個散熱上去唔放散熱膏冇風都可以行到好耐(底用量)
樓主都冇講明佢用咩CPU
所以我覺得斷定過熱太早(如果係好熱情既U成個機會 會變大)

2同3我係認同既
4呢~我冇研究就唔亂講

同埋樓主講既資料
我睇真心覺得唔夠清晰係一個大問題
結果係點都係要等樓主自己試
