My desktop appears to be blue screening and restarting after Win7 hard drive installation.
How can I navigate to event viewer in Win 7 and see when was the last time it crashed unexpectedly?
The Event Viewer log you need to look at is Custom Views > Administrative Events, they will be flagged as Error or Critical
These logs won't tell you much about what caused it, look and see if you have a folder in the Windows directory called Minidump, see if there are any .dmp files in there.
You can then use BlueScreenView to look at the dump file
You can also view events using the reliability tool in Windows 7 for additional information.
Click start and type "reliability". It may show multiple items, select "Reliability Monitor". Then select the day that the event occurred and enjoy!
Just as a side note, the tool is located in: Control Panel > All Control Panel Items > Action Center > Reliability Monitor.
Assuming the blue screen is not preventing Windows from loading...
Or, right-click Computer and choose Manage, and then chose Event Viewer in the left pane.
