Hello guys I got a big issue, I tried restarting my computer but when the monitor was supposed to turn on it said "no signal detected", I look inside my computer, and it seems like all the fans that are supposed to be running, the graphic card's fan is running.
The two fans on the back of my cabinet is running, the Processor's fan is also running, I have a hard time figuring out what the problem is, I tried the monitor on a laptop and there is nothing wrong with the monitor, i also tried another monitor on the computer that has the issue,
and it also says no signal detected. is it the power supply? cause I really hope that's it I'll give you my spec or at least as well as I remember it.

p.s also when I click the front off/on button on the cabinet, after the screen shows no signal detected, to shut it down, it seems to shut the computer down a lot faster then it used to, normally I would have to press it in for a while to for it to completely shut down but not now it seems.

really hope someone can help :) need more spec info please ask. :)

graphic card: Nvidia GTX550Ti 2GB
Processor: Intel Core i5-3570K, 3.40GHz,

Well I had some issues with a Avermedia gamer portable capture thingy... I tried to change the audio in the Avermedia control program, but it started to crash when clicking it so I decided to restart my pc

So I tried unplugging the pc completely and looking inside no cables are touching anything they shouldn't I believe, but its still only working when I plug the monitor directly into the motherboard not my graphic card... any one knows why this is?
