At what time did my computer crash?

Or, in other words, does Windows have a system log? (Many of my 64,000 readers will make fun of me for such a naive discovery, but lo, after 13 years messin' with computers I did not know. "Event Viewer" in Windows XP is the answer. It records (some) actions by the operating system and other applications, so that you can get an idea of what happened when. In order to start it, do "Start > Run" and type "eventvwr" in the "Open:" textbox follwed by Enter. A window like the one in the picture will open and you'll be able to know that your computer has been functioning at least until 10:11pm yesterday (whew!).
