UPDATE March, 2010: I’m seeing a lot of search traffic to this page for Windows 7 reboots; however the following article won’t be of much use. Instead what is happening is caused by the Windows 7 Release Candidate time-out. Beginning March 1, 2010, the Release Candidate will reboot itself bi-hourly. Come June 1, the copy of Windows 7 RC will convert to a non-genuine copy. The solution is to upgrade to a retail Windows 7 release or go back to the operating system you were using before the Windows 7 Release Candidate.
I’ve been using Windows 7 Beta 1 as the primary OS on both my laptop and desktop. Sure, call me crazy, but up til now, it’s performed admirably. Now that I’ve been forced back to Vista on my desktop, it feels… old. The core of the OS may not have changed, but the usability changes added in Windows 7 make it completely different, in a good way. As I said to a Microsoft recruiter a few weeks ago, Windows 7’s UI just works.
Now back to the topic at hand; my desktop started rebooting itself randomly today. There was never any warning; no BSODs or error messages of any sort. Event Viewer didn’t tell me anything helpful either. The reboots happened at random, but the system was never able to stay on for more than half an hour without restarting. Figuring it to be a hardware error, I booted back into my Vista partition for the first time in a couple weeks without issue. No reboots.
I don’t have time to chase issues, so I’ll be slumming it out with Vista until reading week. At the very least I can reinstall Windows 7.
