请教: 老电脑打不开, 显示如下英文字PXE--M04 杭州佬42011-03-03 15:26:22

别人给我一个以前用过的电脑,说是给我可看看新闻和收发E-MAIL,

我打不开,他来帮忙,也忘了怎么会如此,

特此向热心人求教:

我开机, 出`来如下这些字后,光标还是停在那里  闪动:

我重开机 出现如下:

"System-- is locked,

Press F1 for configuration/setup"

我未动,等一会,自动出现如下英文字:

" The RF-ID Tag has changed

  184 Asset control antenna not detected

  System-Security -- Keyboard is locked

  PXE--M04 : Initializing network boot device Using interrupt 18h....

  System--Security -- Keyboard is Unlocked

 176 The system has been tampered with

 Turn power to your system OFF then On

Your system is now locked"

接连的按F1 和不按F1, 开机和关机几次, 都重复显示上列英文,

光标还是停在最后一句Your system is now locked那里  闪动
