It'll boot into the initial login screen, but after putting in the password, it goes into the "Welcome" screen with the little loading circle spinning. It'll either freeze at this point (cursor frozen too) or it will go into a black screen and freeze up moments later.

I've tried all the available driver revisions for the 400 series, all of which present the same problem. Between each driver installation, I uninstalled and removed them with Driver Sweeper in safe mode. For the time being, I've reverted back to the GTX 295 which works perfectly.

After some research, I didn't find any definite answer for this specific problem. There was someone else with the same exact problem, but no solution as of yet. There was a solution for a similar problem where the boot time was really high and performance was severely degraded. That involved remapping memory values or something. But seeing as I couldn't even make it past the welcome screen, I'm thinking it's a different problem.

I doubt there's any fix for this short of nvidia fixing the issue in their next driver revision. I'm thinking this might be some obscure issue/conflict with another piece of hardware, which I would replace if I knew what it was.

Computer is NOT OC'ed

Any help please...

What version of windows are you using? and have you tried the card in another PC to confirm it is an issue with the drivers and not an issue with the card? Maybe you bought a dud?

Verify that your power connections are all there and good. It sounds like the problem starts when the card starts getting 3d requests.

It the 8 pin psu connector installed? It helps to power the pci-e slots.

Otherwise, you may have a defective card. EVGA support is supposed to be very good; open an incident with them.

Today.... Tested all rails all volts/amps fine, tested video card in 4 other computers with all different power-supply.

Hope an RMA fixes the issue, if not this card is going into a brick wall.
