Random Reboot

Hi,

My wife's PC reboots apparently randomly. For a few weeks I noticed that whenever I looked at it the dialog box advising that the machine had been powered down without shutdown was almost always displayed and the screen was always lit even though the display is set to sleep after 15 minutes. Then I was in the room with that screen displayed, no applications running, no one at the keyboard or mouse, and the PC just rebooted for no apparent reason. As I recall there was no BIOS startup screen, rather it went directly to Windows. My wife doesn't use this PC a lot, and it's never rebooted when she's been using it, so it's possible that this only happens when the PC is idle.

My wife is an unadventurous PC user. She typically uses MS Word and uses Firefox to visit innocuous web sites. She’s never had any infection that I recall. I run MS Security Essentials because it’s unintrusive and doesn’t seem to slow the PC. I always apply all windows updates when they’re disseminated. Other than that no new software has been installed for a long time. The hardware is all original so I haven't overloaded the power supply.

Any ideas on how to fix this would be appreciated.

Thanks,
Mike

You can also run a scan with Malwarebytes Anti-Malware free (doesn't hurt to start trial as you install it).

You can do a clean startup to see if it is a software/service issue - Troubleshoot Application Conflicts by Performing a Clean Startup.
Also check Event Viewer for errors/warnings, anything you can find?

Hi,

I tried running Malwarebytes several times and each time the PC rebooted before it finished. The first time when it rebooted it ran chkdsk automatically at the reboot. Finally I tried again and Malwarebytes finished and found no problems.

After one of the reboots I looked at the detailed information in the error message. It said:
Problem signature:
Problem Event Name: BlueScreen
OS Version: 6.1.7601.2.1.0.768.3

Additional information about the problem:

Files that help describe the problem:
C:\Windows\Minidump\061515-38329-01.dmp
C:\Users\Pamela Albert\AppData\Local\Temp\WER-87656-0.sysdata.xml

I saved the two files mentioned in the message but don’t know how to analyze them. Viewing the dmp file in a text editor isn't useful. What s a good program to view it? Would someone be able to help if I uploaded them here?

Thanks,
Mike
