Every time I boot up my computer, the monitor displays "No Signal." I've tried connecting other monitors to my PC and I've tried reseating my video card already. None of these seemed to work. My computer continues to run fine though, the fans and everything are up and running.
I've had this happen to me not long ago before (Once in June and another just a few weeks ago) and I just vacuumed the insides of my PC to fix it so I assumed it was just dust collecting or overheating. But now, after vacuuming for about an hour or so; cleaning up a ton of dust and letting the PC cool down for about 5 hours, the problem still persists.
Not sure what else to do.
The blue cable is broken, replace it and you should have it working.
I replaced the cable with the one connected to the monitor I'm using now. It didn't work.
Even if the fans are running and the system's getting power, it doesn't mean it's working. check the hard drive light when powering on your computer. If it shows no activity for at most 30 seconds, it's most likely not posting. Their's the very slight chance you killed your computer with a static charge, I hear vacuums tend to carry lots of it.
Also, if your computer has an integrated graphics card, just try that out. If it doesn't, get another graphics card and test your computer with that.
What if it's constantly on? It's not flickering or anything.
Definately sounds like it's not posting. Try using just one stick of RAM, maybe some other configuration. Again, try another graphics card. It sounds like you cooked something though, with the amount of dust you said you cleaned out.
Get any beeps?
I don't have another video card but I'll try playing with the RAM.

As of now, no beeps. I don't remember if I ever did have beeps when I booted up my PC. Most likely I did but maybe I didn't notice them.
You might have knocked off/sucked up a capacitor or another component.
if you have another computer in your house/friends computer he/she is willing to let you use for troubleshooting, try changing the RAM or GPU (try integrated if you have one), if it still doesn't work, your probably out of luck. check your motherboard manual to see if it has a speaker or if you have to plug one into some pins on the motherboard. if you still get no beeps and there is definitely a speaker, your motherboards probably dead (don't go out buying another right away, try every thing else you can in terms of component set-ups and if you still cant get any response, but it powers on, your boards most likely dead)
Either your graphics card is damaged or not in correctly or your power supply is broken and cannot provide sufficient energy to your graphics card.
Suggestion: Check for warranties and get the faulty part replaced.
well there's your problem, you vacuumed the inside of your computer. You might have fried something.
This reminds me of that one time I though my computer was broken because my monitor was hooked up to my computer and it didn't turn on, when I plugged it in wrong. It was sitting in my closet for a half of a year until I fixed it
Alright, found a RAM stick that was malfunctioning and replaced it. Everything's working fine now. Thanks for the help everyone.
