What’s wrong with my PC?

In my computer, I always encounter the “No Input Signal” message when booting my computer and sometimes after restarting the machine. I doubt it that the cause of the problem is with my video card since I’m using an old computer manufactured long before the LED monitors arrived and I just shifted to an LED display after my analog monitor died. Anyway, here’s how to troubleshoot the problem.

First, when you receive the message on your screen, try to turn off your computer. After about ten to twenty seconds (10 – 20 seconds), turn it on then see if it works. If this doesn’t work, unplug the video cable of the monitor from the video port at the back of the CPU then plug it back in. See if this works.

If this doesn’t work, try using a different monitor. This verifies if the problem is with the monitor. If this doesn’t work either, the last to check is the video card. Turn off your computer then unplug it from the power. Open the CPU case then locate the video card. Remove the video card from the slot then insert it to a different slot.

After this, plug the CPU back to the power and turn it on. See if this works. If this doesn’t work, remove the video card again then clean the gold pins with a pencil eraser. Rub the pencil eraser to the gold contact pins of the video card and do it on both sides. When you are finished, finish it off with a clean cloth.

Insert the video card back to the slot and try again. See if this works. If the problem continues, you probably need to replace your video card if you are using a dedicated graphics adapter. On the other hand, if you are using a built-in video card, you need to replace the entire motherboard.
