The log file lists devices and services that load (and do not load) when you start the computer in Safe mode. You can use a text editor to open and view the log file. Use the list of drivers and services that did not load at startup to help identify the possible cause of the startup problem. • Device Manager: Device Manager displays a graphical view of the hardware that is installed on your computer. Use this tool to resolve any possible device conflicts or to identify incompatible devices that might be the cause of the startup problem. To start Device Manager, click Start > and right-click My Computer > and select Manage. Expand System Tools and then select Device Manager.
