GTX 400 series drivers & Windows 7 x64 welcome screen lock up

So to be clear, it didn't work on the other 4 computers?

correct, I should have my card back from EVGA this Friday I hope...

I didn't see the part where you said it didn't work on 4 other computers, sounds like you just got a bad card. RMA should have done the trick so shouldn't need to worry about the new one.

I hear ya but I've had no luck with the GTX's as of yet...so I'm somewhat worried...

If it works for you, i'm going to RMA before I try anything else x,x

Before you RMA it, did you use Driver Sweeper? It's a program you can google for where you can click on the nVidia boxes to erase all traces of nVidia drivers from previous card. I've used this many time when upgrading my ATI drivers since I refuse to use the piece of shit software that is ATI Catalyst. So many bad memories.

Download it, hit safe mode, remove the nVidia drivers. Reboot. Safe mode again, recheck for nVidia drivers; if there are none, reboot. Let it go into Windows 7 normally, it'll probably revert graphics to Basic and 800x600. Then install the latest drivers for your card.

Good luck.

I actually tried 5 different revisions, each time using Driver Sweeper in safe mode between installing drivers. Same issue with every revision.

Got mine working! I have a modular power supply, and there are 4 outlets for the 6-pin GPU cords. With my old GTS 250 I only needed one 6-pin power cord, so when I installed the GTX 470, I needed to connect an additional 6-pin cord. Well the outlets on my power supply are color coded as seen here. So technically I should have been able to plug the red-ended 6-pin PCI-E cord into any of the remaining red outlets.

All I did differently was change the outlet I was using with the additional 6-pin cord and everything works like a charm now. So Ermac, if your power supply is modular, you may want to try this.

And FYI, HW Monitor showed the +12v rails to be working fine. There must have been some strange power management thing going on within the PSU.

Hmm, going from crossfired ATI 4870s to a GTX470.. am I going to run into this same power outlet problem? As in it's not going to plug in the same way my current cards do?

I went from a single 4870X2 to a GTX480 and the 480 came with some wires needed as well as my PSU already having the needed outlets. It tells you in the directions of the card how to plug it in. Shouldn't be a problem unless you have a really bad psu.

[Jak]

Cool beans, I shouldn't have problems then. I don't even know what my PSU is, I guess but it seems like the computer I had made has been pretty good with decent everything in it. I guess I'll know Tuesday. :> Along with my new HD 24" 1080P monitor to replace my LG 17" crap I've used for five years.

ATI and NVIDIA cards both use the same power connectors. Thank god for industry standards. If you ran into the same problem as me, the extent of your solution would simply be changing the outlet you're using on the PSU (literally just unplugging and re-plugging in a cord.)

And if your PSU is anything made in the past few years, it should come with the necessary 6-pin cords. Even if it didn't, the GTX 400 series cards come with these power dongles that let you convert old legacy power cords into the 6-pin connectors you need.
