    When I turn my computer on, only the monitor turns on

    Locked

    by khalid3ahmed ·

    My desktop computer is shutting down without warning me and when I try to turn it on only the monitor lights up, the computer doesn’t working.
    I sure that the power cable to my PC is firmly pressed into the powersupply terminal in the back and I checked inside the PC and I see that the main power connector is firmly attached to the mainboard.
    pls help me, thanks in advanced…

      Does the motherboard LED light up ? …

      In reply to When I turn my computer on, only the monitor turns on

      When you checked inside the PC case, did you notice if the LED was lit, or blinking or what?

      Can you tell us the make and model of your computer?

        My rough guess

        In reply to Does the motherboard LED light up ? …

        would be a bad video card/driver since the monitor is “lighting” up but not showing the not connected image (or it was not mentioned)when they turn on the computer… Another possibility is the computer is over heating.
        But more detail of the problem is needed as OM suggested.
        Can you boot the computer into safe mode? Can you find any link to the computer crashing? High cpu load? Video game running? Any error reported in event viewer after the crash?

        my motherboard doesn’t have a LED

        unfortunately my motherboard and powersupply doesn’t have a LED.
        I built my computer by myself.
        I have a MSI MS-6540 motherboard, 512 MB DDR1, Intel Pentium 4, and I’m running windows xp.

        Voltage Siwtch

        In reply to We need to know more about your computer..

        Are you running the wrong voltage…240 volts. It should be 120 volts (in USA). Your power supply may be bad or (during a move of the CPU) might have a bad connection with the motherboard. And like it was said do you have lights. Some computers have “ABCD” lights located on the outside of the case near the audio/mouse/USB ports (on back of Desktop). (Depending on your computer) All the lights should be lit up. We need more information to give you troubleshooting.

        Have you updated your bios?. Update here.

        You might need to use another computer to download this onto a floppy disk. When you have copied this to a floppy place this into the computer in question and go into the bios (press either F2 or Delete buttons on your keyboard, or what key/button that is related to your bios) and go to the bios section that does the update and follow the on screen instructions.

      This might sound silly but you can try and replace the bios battery.

      Look at your motherboard and see if it has a round silver battery with the markings like “2032” on it, this is the battery, just replace it with another of the same size and number.

      Beep!

      by zack_chimento ·

      In reply to When I turn my computer on, only the monitor turns on

      Is your Motherboard emitting any beeps when you attempt to turn on power for your computer?
      If not: you have a problem.
      More then 1 beep: you have a problem.
      I would refer to the motherboard’s documentation or MSI’s website.

        there is no beep and the monitor light is still on

        by khalid3ahmed ·

        In reply to Beep!

        I think the problem is in the motherboard, because if the powersupply doesn’t work the monitor light wouldn’t be on.

          If you have no beep coming from your computer…

          Then the motherboard is at fault. Try everything from taking out the memory and replacing them, take out the graphic card and replace, test the power supply with another one of a little more power.
