Windows 7: Win7 x64 random reboots

24 Aug 2010   #1

Windows 7 x64 Pro
Win7 x64 random reboots

Over the past 3 days my PC has automatically rebooted at least 5 times. It has also frozen twice (with the screen filled with garbage - a gazillion repeats of a small section of the last active window, I think). No BSOD.

I see no log entries reporting anything at the time of failure, but on reboot it logged
Log Name: System
Source: Microsoft-Windows-Kernel-Power
Date: 8/24/2010 9:28:02 AM
Event ID: 41
Task Category: (63)
Level: Critical
Keywords: (2)
Computer: Patrick-PC
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

The previous system shutdown at 9:26:14 AM on ‎8/‎24/‎2010 was unexpected.
The PC is fairly new - 6 weeks old - and has been running fine until now (except for occasional hangs during shutdown of "sleep").

Any particular reason you mention my HHDs rather than my SSD C drive? (Please say "Yes". )
I don't really know what to look for in the logs, but I see that over a week ago I had a number failures writing to pagefile.sys which makes me worry about that SSD. There were no crashes that I remember (unless those were during the shutdown hangs), and there are no similar log entries at the recent reboot times. No minidumps, either.

I don't know what diagnostics are safe / recommended for SSDs. I hate doing unnecessary writes and I assume any diagnostic does a bunch of writes. And speaking of unnecessary writes, I bet I want to move pagefile.sys and hiberfil.sys over to one of my HDDs - especially if I've got a flakey SSD. Yes?

Poke, I assume that DJROD meant the system drive, in this case the SSD. Not everyone remembers to note the difference. I cannot find a test specifically for SSDs, but HD Tune should work fine. I recommend using the trial of the Pro version. It only works for 30 days, but is much better than the free version.

Also, don't worry about the limited number of reads and writes to an SSD. It will still last a lot longer than any HDD will. The pagefile is almost never used if you have 3GBs of RAM or more btw.
