我刚刚在主板 ASUS P8H61-M 上安装了一块 NVIDIA GT740 显卡。我将显示器连接到 VGA 端口,它显示“无信号”,尽管显卡的风扇正在工作,所以我猜它插在 PCI 上是好的。如果我将显示器连接到集成卡上,它工作正常。
我在一台 Ubuntu 16.04 机器上,如果我运行lspci
,则不会显示显卡;它未被检测到。我被困住了,不知道该怎么办。
这是我的 BIOS 信息:

我看到 BIOS 可以更新,这可能是原因吗?
答案1
检查卡是否正确插入 PCI-E 插槽。可能并非所有触点都有触摸功能...
另外,检查 PCI-E 插槽是否有杂物,这些杂物可能会阻塞接触。如果这没有帮助,请在不同的 PC 上尝试该卡。如果在那里也检测不到,则该卡可能有故障。如果检测到了,则可能是主板有问题。
