It wouldnt be the processor, either the graphics card or the mobo, but im unsure on the mobo, cause most monitors did not work with my old video card.

Do you hear any beeps when you power up...

2 then 4 then 2 any groups of three

Powerup should give you one beep....
((Not one long beep))

You cant assume anything is working just because the power supply fan spins up...

Start by stripping the system down to the bare essentials... unplug drives...
Remove all but one ram chip (if you have multiple)
Remove all cards exept the video card and try it again....

And NEVER power it up without a CPU fan in place....

Also, you gotta check your basics. Cables, connectors, etc. I know this is a bit obvious but you would be surprised at the multitude of people who dont do this .

Actually...it very well could be. Sometimes the processor isn't seated right, or there is a bad pin, or something else. I'll update this post should I find any other causes.

For now, make sure it's all seated in there real tight. :mrgreen:
