Computers have been designed to be relatively idiot proof via color codes as well as matching shapes and sizes of various connectors. Despite the best of physical advances, the occasional I/O device error still arises and an avid computer user should know what to do without having to run to a guru. Most times, this event is caused by the system experiencing a hiccup from reboot neglect. As God rested on the Sabbath, computers also need a break. If one cannot recall the last time the system was rebooted, it is probably timely to do a restart and refresh memory chips and diodes for greater efficiency.
If the refresh regime is adhered to, device I/O errors can still be caused by outdated versions of device drivers. Although modern practice adopts the plug and play approach, ability of devices to work with systems is dependent on drivers. In the event the device driver is outdated, one can simply update the driver to the latest version by popping in the CD containing the latest driver. Alternatively, one can visit the device’s website and download the latest. The operating system may also contribute to the problem if its updates are not sufficiently current to interact with the latest release of device driver. The similar can be performed to update the system accordingly.
Updates done and no progress seen, one game to venture further can opt to go where the no IT-savvy man has gone before. A disabled hardware can cause an I/O device error to appear when it is requested for use. This can easily be solved by maneuvering to Settings and then the Control Panel menu. Upon selection of the System option, the Hardware tab allows the user to peruse the complete list of attached devices via the Device Manager. It is worthy to note that steps may differ slightly depending on operating system in use.
Since a red cross indicates a disabled device, one only needs to enable it by toggling the option. Subsequent windows may follow to prompt the user in the enabling process. Once done, the individual can select the option to troubleshoot and confirm it works. The device I/O error should be addressed and one can go about his ways.
A hardware problem may also be just cause. As such, do not be too quick to come to a decision as troubleshooting involves a process of elimination. Ultimately, one arrives at the answer with patience and persistence.
