Windows 7: Random Restart, No BSOD: Kernel-Power 41 in Event viewer

My computer has recently started randomly restarting, no BSOD, just a restart and windows starts right back up. I'm playing games but they aren't graphic intensive, League of Legends for example.

Basic Info:
OS: Windows 7 HomePremium 64bit
CPU: AMD Phenom II x4 955
Graphics Card: GeForce 9800 GT
Memory: G.Skill DDR3 1600 4x2GB

Thanks for any help.

No DMP files included in upload please try this method


We do need the DMP file as it contains the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.

You may be able to get the DMP files without crashing by booting into safe mode (F8) with networking.

To enable us to assist you with your computer's BSOD symptoms, upload the contents of your "\Windows\Minidump" folder.

The procedure:

* Copy the contents of \Windows\Minidump to another (temporary) location somewhere on your machine.
* Zip up the copy.
* Attach the ZIP archive to your post using the "paperclip" (file attachments) button.
*If the files are too large please upload them to a file sharing service like "Rapidshare" and put a link to them in your reply.


To ensure minidumps are enabled:

* Go to Start, in the Search Box type: sysdm.cpl, press Enter.
* Under the Advanced tab, click on the Startup and Recovery Settings... button.
* Ensure that Automatically restart is unchecked.
* Under the Write Debugging Information header select Small memory dump (256 kB) in the dropdown box (the 256kb varies).
* Ensure that the Small Dump Directory is listed as %systemroot%\Minidump.
* OK your way out.
* Reboot if changes have been made.
