      Question?

      I didn’t really see a question there, did you have one?

      Also, please provide some more info. Does your machine shutdown following normal shut down procedure, just automatically after 1 minute of up time? Is the PC actually turning off or are you just losing picture on your monitor?

      No monitor signal

      Did it ever work? Did you recently move the PC, or add a graphics card? If you don’t see the system POST (bios splash screen, etc) sounds like you may have a dedicated graphics card, but the monitor cable is still connected to the integrated VGA port (which would be disabled if you added a graphics card).

      A few things

      Check the power supply, it could be overheating and shutting down. Also, check that the CPU fan is spinning and has white grease under the heatzinc.

      If the PC is just shutting down the monitor signal and not the whole computer, then power is not an issue and could be the monitor.

        things to check

        Before finding the shutdown problem check the monitor signal.
        You don’t mention is tha monitor on stand by or not powered at all? If on stand by:
        If you have video controller onboard and a separate one check where the monitor is connected.
        If not powered check power cords 🙂

        For the shut down:
        Check CPU for overheating. Thermal grease and air coolers.
        Check PSU if working properly. Disconnect most devices and leave only coolers and the bootable HDD. Remove any PCI cards, floppy, cd rom devices etc.
        Boot the machine and see what happens.
        Also check the mainboard battery.
