Thanks for the reply guys.
Yes the fans do spin.
I removed RAM but still no beep codes from BIOS.
I cant remove the video card because it's embedded in the mother board.
The PCI video card that I mentioned was one that I installed when I thought the video had gone out on the mother board.
I believe the mobo is getting power because the CPU fan and 80mm case fan are powering up.
Also, I installed this card and it's also getting power.
I dont know about the option of removing the mobo?
It was working okay and just suddenly the display went out.
I dont believe there would be a grounding issue after it worked fine.
I could see that if it was a custom build system.
