Okay, this is frustrating me to NO end. I dont understand why this won't work, but it is steadfastly deciding not to.

My rig is in my sig. It's 3 years old, needs to be replaced but it's going to have to live for the next 6 months or so. DFI nForce4 Ultra-D, x1900xtx. Searched and searched, but can't find a solution to this problem.

Here's what happened: I bought a new 24" monitor, works flawlessly. I wanted to hook it AND my 19" up, no problem, right? Both are DVI, two DVI ports. Plug up and go!

Not so much. Turn the machine off, plug in the DVI cable, turn the monitor on, then turn the machine on, won't POST. 1 long, 2 short beeps. Video card or display error. That's wierd. Okay, unplug the new monitor, reboot, same POST error. Reset the BIOS, same thing. Make sure it's getting power, etc, etc, pull CMOS battery, yadda yadda. Nothing. FINALLY, I decide to reseat the video card, which is a pain in the keister. Lo and behold, it boots again!

So I figure my problems are behind me. I plug in the new monitor and the old one while in windows, it finds it, configures it, I play EVE on it no problem for 4 hours, reboot it a few times (using restart from WINDOWS, so it doesn't go through POSTing), no problem. Shut her down for the night, bring her up in the morning, SAME POST CODE ISSUE! 1 long, 2 short beeps. Go through the same process, finally pull/replace the card, and it works again, but I left the 2nd monitor unplugged, but I had the 24" plugged in this time instead of the 19", and it works. So it's NOT the monitor compatibility with the gfx card.

Frankly, I'm baffled. I cannot understand how nor why this would happen. The ONLY thing I can think of is that when the card sees that it has two monitors attached at POST it doesn't know which to display on, gets confused and then goes into "holy crap something is wrong!" mode. Is there something I need to enable in my BIOS? Is there some monitor specification setting I don't know about? Have I missed something? Am I condemned to never turning my machine off again?

Any and all help is appreciated,

I have basically the same mobo (lower model) and it was plug and play for me. That is strange.

All I can think of is the jumper arrangement not letting the card draw enough power but that probably isnt the case

Okay, I THINK I have it taken care of. I will confirm this in a minute. I had to BOOT with the 24" connected ONLY, then connect the 19" as a secondary monitor, swap the 19"s DVI cable, then reboot a couple times, then turn off, and voila! It POSTS.

Don't ask me why this worked. It just seems to have. Will confirm this with several reboots and power off/ons later.

Thank you all for your input!
