Hey all!
was using my computer and it just froze up, left it for a while and it was still frozen, so i turned it off at the plug.
Tried to turn it back on and all i get is a blank screen with a blue box flashing "DVI No Signal" and the CPU fan is at a constant speed.

I have tried;
-Removing GPU.
-Removing RAM.
-Unplugging HDD and DVD drives.
-Leaving it for a while.

After this, i get nothing!
Thanks for any help!
Daniel =(

EDIT:
Just poked around in the case and found my 4pin 12V cable to the motherboard wasn't plugged in all the way...:sarc:
So easy to miss stuff like that :o

Yha, lack of power to the cpu is a sure no boot issue.

Lucky it was a easy fix.
