一直重開機!?

我的電腦最近怪怪的~~突然玩到一半就給我重開機~~
然後就都沒有畫面ㄌ~~只聽到一長聲三短聲的聲音~~我想應該是顯示那沒有插好~
我用ㄌ很久也是一樣~~然後我就換我朋友的顯示卡來測試~~也是一樣~~
我把顯示卡已經插到底嚕@@@~還是一直叫~~~再用ㄌ幾次~~嘿~~ok嚕
隔天~~再開機~~雖然沒有聽到叫聲~~但是要到98的畫面時它都一直重開機@@
why???是顯示卡和agp的插槽接觸不良還是我的power的問題??
我的主機版是:微星
顯示卡是技嘉Geforce Mx200
記憶体:創見256MB
謝謝!!

這是BIOS嗶聲解釋但是還要看你BIOS是屬於AWARD或是AMI的因為BIOS不同嗶聲解釋也不
