ok, here's my problem:
I've just built a new PC with just the Motherboard, RAM, CPU/fan, Hard Disk, AGP graphics card and Floppy Disk Drive connected for the moment.

When I turn the power on however, the monitor stays blank. All the fans start whirring and I hear 4 or 5 bleeps, but the monitor remains on standby, black.

I tried booting the PC with a startup floppy in the drive, but to no avail.
I also tried removing and then putting back in the battery but still no change. Then I tried swapping over the graphics card with another one from another computer, but still no change.

Then I unscrewed the Motherboard and everything connected to it, and rescrewed it back in place again, and still no change.
I've also tried using 2 different monitors, with the same results both times.

Any advice about what it could be or what other tests I could do would be very much appreciated.

BTW my cpu is an amd 1900+xp and the m/board is a gigabyte GA-7vtxh

The 4 or 5 beeps coming from the speaker is a bios post code error problem probably relating to bad video.....

But when I swaped round video cards it made no difference, so I think its not a video card problem.
Or could it be that maybe the agp slot is buggered? Or would this cause a different error?

When I swapped the video card round with another similar one from another system that is.

Well actually now I'm not sure if they're beeps at all.. they're certainly not as loud as normal beeps and I have to listen right next to the computer to hear them, but I think they are coming from th speaker because when I unplug it I dont hear anything

Are you sure the agp card is incompletely. I've had that happen to me several times. Try taking it out and reseating it making sure it's ALL the way in. If that doesn't work then check your manual for the location of the pins and procedure for how to clear CMOS. Then reboot. If you get your video going don't be surprised to see a check sum error. Just go into BIOS to load optimal or default settings then reboot.
Hope you get it going.

YEah I've unplugged and then replugged in the agp card various times now, and it doesnt make any difference, so I think the video card and memory arent the culprits.
As I said before too, I tried to find a way of resetting the BIOS but there was nothing in the manual or on the motherboard about how to do that, so I had to physically unplug the battery and then replug it in after 20mins or so, which would hopefully have reset the BIOS.

Hmmmm, have you a PCI video card to try? This would surely tell you if it is an AGP slot problem or a flat out bad board.
