Starting my computer for the first time, no signal to the monitor.

Hi so I've put together a "computer" but I'm having trouble starting it for the first time, here what I've observed:

-When the PSU is turned on and I turn the case power on too the fans all start up and I can see a bunch of green lights

-There is NO beeping when it is turned on

-The Monitor does not detect anything;
* When I turn it on a blue/green screen with a mouse appears, the illustration indicates that it is weighting for a movement of the mouse. After 5 second it goes black again. I have tried 2 mouses (both of witch where usb) one lights up the other does not but neither trigger the monitor.
* When the DVI connection is taken off the monitor turns on and a no input screen appears

-The on light on the case does not light up

I have put very much effort into making sure that all the connections are right and have even brought it into a microbites to get it checked (they said it was all done right). They did not take very much time so it is still possible some thing is not right but as far as I can tell everything is exactly as the manual states it should be.

I believe it would also facilitate it for you if I include the computer specs so here they are;

CPU: AMD FX 8150
mobo: Asus sabertoth 990fx
RAM: G Skills, rip Jaws 4Gb x 2
Memory: Corsair 120Gb solid state drive
Case: Fractal design Core 3000
Video card: Asus GeForce 560 Ti top

That should be it but I feel like I'm forgetting something so ya PLEASE help me any help is good help,

Thank-You

Im kinda new to this too.. But i remember having kinda the same problem.

Basically how i fixed it was i made sure the DVI connection cable was plugged into the video card DVI slot instead of the motherboard DVI slot.. I guess you could try that and see how it goes.. :) 

EDIT: Maybe switching from video card slot to motherboard (or vice versa could do the trick)

As far as I know my Motherboard doesn't have a DVI slot.

Sorry, Thanks for the try :) 

To help any one having the same problem here is the fix. I brought my computer to micobites and they told me that sometimes with the Sabertooth 990fx mobo the bios will not start up with the processor I had. They had to fix it by removing my processor putting in a different one, update the bios then reinstalling my processor.

And you thought Friday the 13th was a bad luck day! LOL. You usually have to make sure video settings in the bios are correct. Sometimes the primary video source may be set to the wrong source. Always check for mobo/CPU compatibility... it can be a real headache at times. Good feedback. I love it when people follow up on their posts. You just taught me something! :hello:
