Hi ajss2595,
When you cleaned the fans, did you clean the fan on the video card? I would verify that your video card fan is actually spinning.

If your monitor is blank, the normal troubleshooting steps would be to (1) try a different monitor, and (2) try the monitor on a different computer. If you confirm no signal from the Optiplex to any monitor, then you have a bad graphics adapter.

I just did what you told me and nothing, no signal from the optiplex. Do I need to change the graphics adapter or it can be repair?

Did you try reseating the video card in its slot? Since you cleaned inside, you may have accidentally dislodged the card or a cable...
And you still may have a CPU fan problem, based on the error message in your OP.
