Mysterious reboots

This computer is virus-free and malware-free, but mysteriously reboots at random intervals. It doesn't seem to matter whether the computer is busy or not; it's left on overnight and several reboots occur even then (as indicated in the event logs). Before I start tearing apart the hardware I'd like to ensure that the computer hasn't been hijacked. Here's the dds log:

Hello and welcome to Bleeping Computer

We apologize for the delay in responding to your request for help. Here at Bleeping Computer we get overwhelmed at times, and we are trying our best to keep up. Please note that your topic was not intentionally overlooked. Our mission is to help everyone in need, but sometimes it takes just a little longer to get to every request for help.

If you have since resolved the original problem you were having, we would appreciate you letting us know. If not please perform the following steps below so we can have a look at the current condition of your machine.

If you have not done so, include a clear description of the problems you're having, along with any steps you may have performed so far.

Upon completing the steps below another staff member will review and take the steps necessary with you to get your machine back in working order clean and free of malware.

If you have already posted a DDS log, please do so again, as your situation may have changed.
Use the 'Add Reply' and add the new log to this thread.

Thanks and again sorry for the delay.

We need to see some information about what is happening in your machine. Please perform the following scan:

• Download DDS by sUBs from one of the following links. Save it to your desktop.
  • DDS.scr
  • DDS.pif
• Double click on the DDS icon, allow it to run.
• A small box will open, with an explanation about the tool. No input is needed, the scan is running.

• Follow the instructions that pop up for posting the results.
• Close the program window, and delete the program from your desktop.

Please note: You may have to disable any script protection running if the scan fails to run. After downloading the tool, disconnect from the internet and disable all antivirus protection. Run the scan, enable your A/V and reconnect to the internet. You can find information on A/V control HERE

This problem turned out to be caused by a bad memory stick. There were two 1G DDR2 memory sticks installed, one of which was failing enough to cause periodic reboots but yet not bad enough to prevent the computer from running most of the time. I discovered the problem by running the "Memtest" memory diagnostic tool. As soon as the bad stick was removed, Memtest ran perfectly and I'm presuming that my computer will do the same.

Hello

Thank you for posting back. I'm glad that your computer problems have been fixed. Since this issue seems to be resolved, this thread will now be closed.

In case you experience any problems with the computer, please Start a new topic.

Happy computing,

Orange Blossom
