开机显示红色you have not connected the power 。。

显示“you have not connected the power cable to your video card.please refer to the`getting started guide`for proper hardware installation",知道是视频卡没装好，但想安装驱动或重新装机都没法装，一开机都不读碟，就显示以上的红字，我该怎么办

请大哥大姐指教
PS:1、主板线也重插过，，
2、系统盘放进去，正常是显示BOOT FROM：CD，但却一直是显示红色的you have not connected the power cable to your video card.please refer to the`getting started guide`for proper hardware installation，，所以无法重装
3、显卡已拆下来清洗N次，问题依旧，，，
