The computer comes on, but nothing appears on my monitor

Whenever this kind of sickness is attacking the monitor shows:

No Video Input

What should I do? :cry

Also, whenever I'm putting the monitor plug in the CPU, I need to position it in an awkward position so that it can work properly. Plugging it perfectly won't work.

 

I've read something about this problem:

In other words, Windows never shows up. You may have a monitor problem. Try using another known-good monitor on the computer and see if anything shows up on the screen. If the second monitor works, the first one is bad. Monitors are not worth repairing. Just buy a new one. Never open the back of a monitor to fix it. The capacitors inside monitors store electricity. You could be injured or even killed.

If the screen is dark, it could be a video card problem. First, find the video card. This is a circuit board that fits into a slot in the motherboard. The cable from the monitor connects to the VGA (video graphics adapter) port, which sticks out through the back of the computer. If the VGA port is part of the motherboard, the video is built-in. You can't fix that. Otherwise, it will be part of the video card.

Assuming you have a separate card, be sure it is firmly seated. The front end of the card can rise out of the slot inadvertently when the back end is screwed down to the computer frame.

If you have a computer that is working perfectly, turn it off and remove the video card. Put the card that works in the problem computer. If the system works, you need a new card. If you don't have an extra card to test your system, buy a cheap one ($30-$50). If it doesn't solve the problem, take it back.

You can spend hundreds of dollars on a video card. But if you're running business applications and surfing the Web, buy on price. The expensive stuff is for serious gamers.

Can you please explain those words that's in red font?

 

.
What connector do you use? Dvi Or Vga?
It sounds like you may have a bad connector on your card.

 

unpluged it If u have and Force it you may have Bent to Broken some pin's in the connector look at the Connector and make sure the the pins are Strait
if any are bent VERY VERY VERY VERY VERY!!!! Carefully take Something and Try to make them Strait BEWARE if you Bust a pin there IS No fixing it and you will have to buy a new monitor

 

It's already okay. Thanks for the reply! I just opened my CPU and see if it properly was fixed in. I just remove some screw and tighten up a bit and bwuala its fine again!

 

Im glad to hear about that screw in the cpu fixed your video problem. ed
