I moved my computer, I set it back up and plugged everything back in. Now when I turn it on the fan runs and runs but the monitor will not come on - it just displays the message NO SIGNAL. I've tried unhooking everything and starting from scratch - still the same thing. Everything has power going to it. My computer has done this before when I have lost power, but usually after turing it off and letting it rest for a while, the problem corrects itself. I have let it rest for several hours a few times already but it hasn't fixed the problem this time. Any suggestions???

Hi and welcome to Geeks to Go. Remove the cable connection from the back of the computer at the video card (the VGA cable) and inspect the pins. Perhaps one of them got bent or is broken off? check the connector on the video card as well

How do I check the connection on the video card?

Unscrew the VGA connector from the video card. It has two thumb screws holding it in. Then inspect the pins on the male connector (the cable). Examine the female connector using a flashlight. There should be an equal number of open holes corresponding to the number of pins on the cable.

All of the pins are there and none of them appear to be bent.

You could try opening the case and re-seating the graphics card. If that does not do it, verify the monitor works by connecting it to another pc or take a known working monitor and connect it you this pc. It is possible your graphics card died. You might also check to make sure your monitor has only one input. I have a dell 21 inch CRT that has two inputs, and the selection is made via a small button on the font of the monitor. One time I accidentally hit the botton moving it to input 2 when the cable was connected to input 1. I had no documentation explaining this and it took me a while to figure it out. I connected a known good monitor to the pc and it worked so the problem had to be the dell monitor...then I noticed that small button.

Thank you. I opened it up and dusted it out (it was very dusty) and just disconnected and reconnected some things. Don't ask me what they were,but it worked. When I closed it back up and started it again everything worked. Hopefully the problem won't repeat itself. Thnak you again for your help!
