No Signal Input

Specs: Windows XP
Let me start by saying that I know very little about computer "jargon," so when I read some of these posts about video cards and such, I am still lost. I am very sorry, but need things in lamens terms. My computer screen has been saying "no signal input" before starting up for a while now. But, it starts up and things work fine. However, now the computer just doesn't want to work sometimes, and sometimes it does. Now, most of the time nothing will happen after it says "no signal input," but other times it will work if I unplug the power cord and plug it back in. If I have used the computer earlier in the day, then it seems as though I have to unplug the power cord for several hours before I can get it to work again a second time. There is an issue with the cord now that runs from the monitor to the cpu (if that's even the correct term) because my color is off and if I jiggle the cord the colors change. Anyway, sorry that I couldn't understand your responses to others (I don't even know what a video card is and I saw that mentioned a lot). Thanks for any help you can give. I really cant afford to have a tech look at it right now. Great day to you =)

hi nikki, first of all, unplugging the tower via power plug is not a good practice. You can damage your motherboard that way. The safe way to shutdown a pc is either the start/shutdown way, and if that doesn't shut it down, then press and hold the power button on the front of your tower for about 5 secs or more and it will shut down safely.

Sounds to me that if you unplugged the monitor from the tower numerous times that you prpbably bent some pins in the connector. Check and see if that is what is happening. If so, you will probably need either a new cord, or if the cord is not removeable, you will need another monitor.

Some HELP in posting on Computing.net plus free progs and instructions Cheers

I agree with XpUser4Real. It sounds like loose/broken wires in the monitor cable connector. This is a common when people move their monitor around a lot. It flexes the cable and the wires eventually break.

If you purchase an LCD monitor, they usually have replaceable cords.
