The most common monitor connectors are shown here Perhaps the one at the bottom of your tower is a digital one like the one on the left and comes from a Graphics card although that sounds unusual as the location of a graphics card slot is rarely at the bottom edge of the motherboard. If the connector on the motherboard is similar to the one on the right then it is a VGA analogue connector. If you do indeed have two graphics outputs, one from onboard graphics and one from a separate graphics card, you may need to select which one to use in your BIOS. However this reply should get your thread bumped back to the top and others may be able to help.

From your post then the one at the bottom of the tower is a VGA connector for the monitor and that is where it should be plugged in. The connector on the motherboard is a serial port, an almost legacy device once used for connecting external devices such as a mouse or an external modem. As you do not have VGA on your motherboard then you do not have to enter the BIOS at this stage.

If you have plugged your monitor into the correct output at the bottom of your case and you do not have a signal at all when you boot up the first thing to check is the monitor and its connections. Does it work with a different PC? If so you can rule out the monitor. If not then have you turned up the brightness and contrast so that objects on the screen can be seen? Is there any indication that the monitor is receiving a signal? Very often an indicator on the monitor will change from red or orange to green when a signal is being received.

Having made sure that the monitor is good then you have a problem with the PC itself. When you switch it on does anything light up? Do fans and hard drives whirr? Do you hear a beep from the PC to show that the POST has been successful? Some of those will indicate that the PC is receiving power and booting up. If none of those are happening then you have a PC problem that needs investigating - could be a failed power supply among other things.

If you have signs of life from the PC but still no picture on a good monitor then the chances are that the graphics card has failed and this will mean taking the covers off the PC to check that the Graphics card is securely seated in its socket, that its fan (if it has one) is spinning and not covered in dust/fluff.

Try these things first and then report back how you get on.

Excellent advice from chub_tor if I may say.

To save me looking into this thread again could you possibly click on the tick to the right of chub_tor's answer that helped? Shows that the problem is resolved.

Thanks.
