Help! There are gremlins in my computer...

[daddyphatsax]

I am stumped about what is causing problems with a computer I am upgrading, so I was hoping someone could help me out. The computer is an HP 8679F, which is a P3 667, 382MB ram, 30gb hdd, dvd, cdrw, on a via 694 board. I upgraded the onboard video (Vanta) to a geforce4 440mx AGP. After updating the bios and disabling the onboard video, I am left with a pretty serious problem. The computer will not post with the monitor plugged into the video card. If I leave the monitor unattached, I get one happy little beep, and then I can reconnect the monitor and it works. But if I try to boot with the monitor plugged in, I get one long and three short beeps, a video problem. What the heck could be causing this and how do I fix it. Card (geforce) works fine in other computers, and other cards (Matrox G400) work fine in this computer. Please help me.

That is most strange. How did you even think to boot without a monitor attached and then hook it up later? Anyway, my only thought is possibly may be a powersupply issue. The nVidia card will surely draw much more power than a Matrox or the onboard. Sorry I can't help more so consider this a bump.

I had that problem in reverse before - a system would beep if it had no monitor. And I'm currently using a 694T chipset board. I'll look into it, but that sounds pretty whacked out. Perhaps you need to tweak some BIOS settings ...
