Plz help! ti4200 boot problem!

[DiabloNY]

Hey guys - hoping some of you experts can shed some light on this for me:

I have an Asus p4S8x system with Intel 2.4GHz processor, Pioneer DVD drive, Sony CDRW drive, one case fan, and one 80gb Western Digital 8mb cache 80GBHD that's been working flawlessly for me.
Recently, I got a the PVT28ANC XFX GeForce4 ti4200 128mb VIVO DVI video card.

After about 8 hours of use with the new video card, my 300 watt evercase power supply stopped working - that is, it is no longer able to power up my system. When I press the power button, I hear the system struggling to turn on, and it continues to struggle as long as I hold the button down.

So I got a new Antec SL400 400watt power supply, and it has been working well for the past couple of days with one exception - if the computer has been shut off for a while, I have to hold case the power button for at least a second or 2 for it to finally boot up (if I release the power button too quicky, it does not power on). This only happens if the computer has been powered off for several hours, but it does not happen if the computer has only been powered off for a few seconds/minutes. So if the comp is "warm", one gentle, quick tap of the power button will boot her up, but if it has been powered off for a extended periods, I have to hold the power button for a few seconds for it to boot up again. It seems as if the PC is struggling to turn on, but shouldn't a 400 watt Antec power supply be enough? I have done several trouble-shooting tests summarized below:

1-When my old TNT2 vid card is installed in place of the new XFX card, this problem never occurs and the system powers up fine. 2-When only the motherboard, CPU, RAM, and fans are connected, the sys also powers up fine.
3-I have also tried power on by PS2 keyboard, and it will boot up if the comp is warm, but will not boot up if the comp has been off for a while. Only pressing the power button on case for 1-2 seconds will power the system on - this rules out problems with ATX case button.

Any input/troubleshooting ideas would be greatly appreciated!

I have several friends who have owned GF2 mx somethingorothers and have complained about the same thing. Problems with no video on boot. I thought that nvidia had fixed this problem by now. Maybe it's just a defective card. Of course, it's probably a problem with the card maker rather than Nvidia.

What happens when you have the 4200 in and disconnect your optical drives or try booting without your fans?
(not sure how many you have hooked up).

Also, try booting up the system with your old TNT2 and see if that still makes a difference.

Thanks for the replies,

System boots fine with old TNT2 system (as I stated in initial post). Booting with ti4200 in and NO drives at all still results in same problem. I haven't tried disconnecting fans yet tho... Trogdor, I have a GF4, and my problem isn't that I can't get video - the problem is that my sytem seems to struggle from a cold boot after it has been powered off for a while.

Try plugging your Fan on the video card to the motherboard or get a 3 pin to 4 pin molex adapter and plug it to your 12v rail
Your AGP slot may not be providing enough juice. This would free up some power.
I do it on all my video cards, first thing now.

Billy - thanks for the reply. That's an interesting idea. I'll see what I can do...
