No video

No video, I have installed a PCI video card (tested).
I disabled built-in AGP by setting J11 jumper to 1-2 (what I think is
1-2). I have installed new memory (not tested) and hard drive. There is no audible post. The monitor,keyboard and mouse works OK on another PC and the CD-rom drive has power. No activity from HD. I unplugged and held power switch for 30 secs and I just removed battery. I will replace it in 24 hrs. I my motherboard fried?
Please help. Thanks
