求救! mouse keyboard冇反應!!

sisiyip

開機後去到load緊window mouse底燈熄左...
入到window mouse keyboard冇反應...
仲彈左無法辨認硬件...
我見好似所有driver都冇晒咁...

我入過bios, keyboard正常...
setting usb係開啟既...
入過f8安全模式...keyboard mouse都係冇反應...
入過修復模式...但冇錯誤...
係ms dos做過chkdsk但都係冇錯誤...
我都試過冇俾電...但都係唔得...

我部機係vista home. 冇ps2, 只有usb...
麻煩幫手解決冇driver同usb用唔到問題. 謝...
