    Hey guys, I reloaded win7 on this unit, it started restarting on it's own after I choose the shut down option in windows and it shuts down but now "sometimes" when i go to the net it will shut down too and restart, any ideas please?

    Have you checked the power options to see how they are set, Mike?

    Power options set on "balanced" and Turn off display 10 minutes and Put computer to sleep 30 minutes Cindy.

    I noticed the the vga port on the back as been pressed in on one side, could this be a graphics hardware problem?

    I chose safe mode and no restarting, even when I shut down from safe mode I had to use the power button to startup the pc again, I did this 2x so the problem apparently doesn't exist in safe mode.

    Wait a minute, since no problem in safe mode does this mean would not make sense to buy a PCI graphics card, right?

    Since it's not staying on in normal mode, would I be able to run speccy in safe mode?

    I ran speccy in Safe mode, please see attached screenshot but I don't think anything is overheating as that was my first inkling and taking the cover off, nothing is heated up or smells. On the screenshot it shows the graphics cannot be started in safe mode.

    Oh sorry, I have no idea why the screenshot is showing upside down. On the screenshot it shows the graphics cannot be started in safe mode.

    Well, it's working so I can't say that it's damaged, it's bent inwards,

    So can I rule out software and declare this a mobo hardware issue?

    This is probably a driver issue. The restarts are probably blue screens. Look in the system logs for any errors generated during these restarts. My bet is the graphics driver is causing the problem since it doesn't happen in safe mode when the full driver isn't loaded.

    I tried updating the display driver but it showed "the best driver is installed".

    Have you checked the event viewer for errors, Mike?

    Rather than changing out the hard drive, I doubt that is the problem anyway, set the computer to not restart automatically when a system error happens. You can do that in safe mode in advanced computer properties. Once you set that the next time it reboots you'll get the bluescreen with the error code.

    Yesterday I had tried "Disable Autorestart on System Failure" but that did not solve the problem.
