No video at startup - beep code

My PIII, 64mb PC100 RAM, Tyan motherboard, AGP video system was working fine. I saw that I was using a 40 pin IDE connector on a IDE 66 hard-drive and decided to install the 80pin cable. It sounded simple enough.

But the next time I tried to boot I heard the beep code that told me BIOS could not start any video display (I am using an AGP video card).
What could I have done to cause this?
I have since changed the IDE cable back to the original one, checked for unconnected cables and everything, but I continue to hear to beep.
The odd thing is that the computer seems to be continuing the boot sequence even without the display, for I hear the hard drive start and it continues its activity for 30 or so seconds. But since I can't see anything, I can't change any settings to try and fix the problem. Pressing Ctrl, Alt, Delete twice restarts the system and I get the same beebing problem again.
Any ideas?

It is possible you dislodged the ide connector to the Motherboard such
tht it is only making partial contact. Sometimes this will throw off the video
initialzation. Also, check your video card is also seated properly.

Hope this helps
