The tooltip displays the name of the executable that crashed, along with its version and the name of the application to which it belongs. In the case of a single crash, the time in the header of the tooltip is the exact time when the crash was reported.
In the case of several almost simultaneous crashes grouped in the same tooltip, the time in the header of the tooltip displays the interval during which all crashes took place. Each application listed in the tooltip is preceded by its own precise time of crashing.
Application not responding
The tooltip for non responding applications displays the same information as the tooltip for application crashes, but for applications that hang or freeze instead of for applications that exit unexpectedly.
The tooltip displays the stop error code and a brief textual description of the error that caused the device to crash. These are serious hardware or software errors that make your computer halt unexpectedly. For that reason, the time in the header of the tooltip cannot indicate the moment when the error occurred. Instead, it is the time of the first boot after the system crash.
The tooltip indicates that the device was abruptly stopped and then rebooted. Pressing the reset button, power failures or crashes may be the cause of a hard reset. As in the case of the blue screen tooltip, the time reported here is the time of the first boot of the device after the hard reset.
SMART disk error
The tooltip signals a disk error detected in a disk drive equipped with the SMART technology. It indicates an increase in the number of disk writing errors or in the count of reallocated sectors.
