Dell Desktop

Specs: Windows XP
I took the side off of the tower off and blew out all the dust with a can of air, it was pretty bad with dust then when I hooked it up back I turn it on and it sounds like it's going to boot up but it never completely does. I have no signal but everything is on. Dvd opens and all lights are on.

you may have loosened up a connection. reseat everything. Canned air shouldn't hurt anything. You did get everything out?

Maybe a wire is rubbing on a fan. That can stop it from running.

Worst possible thing you may have done is dislodged the heatsink. In which case you may need to remove it, clean off thermal paste, reapply and reinstall.

Don't attempt that now. You need to know how to remove it or you can damage things. I bet it is just a loose connection. push them it all the way.

After rereading your post I think you may have the monitor connected to the wrong port. Look to see if there is more than one place or maybe even an added in video card that you are NOT connecting to.

Can you tell me more about this heatsink? I should of wrote more in detail what I've already tried doing without success. I definitely ruled out it’s the monitor because I already hooked a working monitor from my other computer to it and had the same result, no signal. The fans are working great, running smooth with little noise since they have been cleaned. I have checked all the wiring and everything inside to make sure nothing was loose and everything is in place. I even removed the memory and of course all connectors just to let everything reset with still no luck. When I start the tower up I can hear it like it is starting to boot then it kind of hovers a sound and never beeps and never completely turns on. I hate to bring it into a shop if it’s something so simple I can fix here at home, I’m so stumped.

Describe what the beeps sound like the are patterns of short or long beeps that can tell you what is wrong. One single short beep is normal.
