電惱啟動不了,請幫幫忙看看,先謝謝

那天關了機後就起動不了,電源燈及顯示器燈都亮,機子是W.XP的,台式,一開開關就出來這一大篇字,如下:

We aplogogizefor the incomventience,but windows did not start successfully. A recent hardware or software change might have caused this.

......................................................................


Safe mode

safe mode with networing

safe mode with command prompt

laste knowing...........

start windows normally

這幾個MODE,偶一一都試了還是起動不了~~~這是出啥狀況了?
