    One of our computers (Dell Vostro) has started Rebooting (all by itself!). At the same time the computer lost its network connection, and in trying to segregate the problem I pulled the wireless network adapter out. I find that if the adapter is not plugged in to the usb port, the computer DOES NOT take it upon itself to reboot - and reboot and reboot on into eternity. If I plug it back in, it starts all over again.

    Any suggestions before I call the tech?

    Do a full scan with your AV software, Malwarebytes, and any other anti-malware software you have loaded on the system.

    I have done that already and it shows me nothing. I was going to defrag overnight and see if that helps.

    Are you using any automatic backup software?

    Is there a builtin ethernet port whee you can hardwire the PC to your router/switch? Does it act differently?

    Do you have the most current drivers for the wireliess nic?

    OK, that eliminates the virus that causes this behavior. The defrag may help, but if you are using the native Windows defrag utility it won't touch the system files or boot sector. I use Perfect Disk for defrag just for those reasons.

    I'd address the issues Joe mentioned first and see if that sheds any light.

    This tells me that there are problems the the device or the software and/or drivers for it.

    Remove the device, uninstall all related software and drivers. Reboot the machine, and then follow OEM instructions on installing it as a new device.

    Now running HP Pavilion a6528p, with Win7 64 Bit OS.

    After I downloaded an update on the Zoom software, from another computer, I uninstalled the Zoom software, and the reinstalled the update. I also switched to another Zoom wireless network adapter. That seemed to have worked in that the computer was no longer rebooting every 30 seconds or so. However, it was absolutely impossible for me to get that computer back on the network.

    Our computer guy came in and took the compute with him. He seems to agree that I solved the problem partially, however, he also said MacAfee Anti-Virus software may have been corrupted and stopped working. Since I was off when he brought the computer back. I'm not sure what he did but the computer seems fine. However, then we started having the same problem with my bosses computer late yesterday. I am convinced that he bent the network adapter and that has at least some bearing on this problem, but I could not test my theory because he has to go out and purchase another network adapter.

    All very, very strange; I've never seen anything like this before that was not virus related, but he says the computer was not infected?

    It sounds like the network adapter might very well be the culprit. Please let us know if the replacement solves the problems.

    Thanks.

    You might right click My Computer>Properties>Advanced>Startup and Recovery and UNcheck the automatically restart box and check the Write an event to the system log, to see if that will stop the repeated rebooting and give you a clue as to what is causing the problem.

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!
