When I start my computer I always hear a beep message from motherboard & it displays on monitor that ' No video input/ Check signal' but after that my computer start to work normally. I want to know if this is a problem or just some general messages from motherboard. Please tell me.
Hi, first is try to connect you monitor to another computer just to make sure the possible of a defective monitor. Now, Shutdown your computer and remove the cables and devices the plugged into the computer, take note of the port in which the monitor is plugged, remove the left side panel , locate your video card, and remove all power cable that connects the video card, pull the video card out, examine the pins for any damage, you can also clean the pins by using an eraser and slide it to the pins to clear any dust. Put the video card back on, then try again switching on the computer.
Hi good day…The most common of the beep codes is the video card problem and memory card problem. To resolve this kind of issue, removed the video card into the PCI slot, and remove also the memory card from the RAM.

If you see that message only on startup or before the BIOS screen appears the first time you start the computer then it is normal. This is maybe because the video card is still initializing. But if you see this message frequently like even when restarting the computer then it is a problem with the video card. First thing to do is try to update the video card driver.
Try visiting one of the following links if you have one of these products to get the latest driver:
On the other hand, if updating the video card driver doesn’t work, the only solution left is to replace your video card. If you are using the built-in video card on your motherboard, upgrade by purchasing a dedicated video card. If you are using a dedicated video card and you see this message, purchasing a new video card is recommended because it is a sign of an impending failure.
