摘要翻譯如后:
EIO是ASUS Smart Doctor, 主要是隨著ASUS的顯示卡一起安裝.
當解除安裝時, 可能會造成軟體移除, 但Registry未移除的關係.

解決方法為:
將
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EIO]
"Type"=dword:00000001
"Start"=dword:00000002
"ErrorControl"=dword:00000001
"DisplayName"="EIO"
中之
"Start"=dword:00000002
改為
"Start"=dword:00000003

EIO service is a feature of ASUS Smart Doctor, which comes with certain
ASUS branded ATI graphics display adapter card products.

When the display adapter product software is removed, the driver file (e.g.
C:/windows/system32/drivers/eio.sys) is removed but the registry entry is
left behind, which causes that error to appear on every boot thereafter.

Most users who encounter this error will remember having installed an
ASUS brand product that includes a graphics display adapter capability
(may be built into the mother board), and then having uninstalled the
software for that product. Their confidence in the solution will be
enhanced when they know this is its origin.
