GTX 480 HELP ME OUT

[aldhogg]

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...

Like what dipankar2007ind said; it is a bad card. You should exchange it with another one or keep the GTX 295 since it performs very similarly.

The GTX 295 performs like the HD 5870, but the GTX 480 is better than both.

I had another convo with EVGA, I was told to consider looking at the motherboard and power supply / amps going into the MB.

-I have found nothing conflicting or any other hardware conflicting with the video card, which really leaves to this power hungry video card.

Really starting to think its the power supply, tomorrow I hope to know for sure, as this can be a hard thing to catch unless somebody knows of a good monitor software...I know asus has some but any others?

"Then look for something to the effect of "System status, hardware monitor, pc health, etc" Your looking for the +12V. It should be running between 11.9~12.3 (Keep in mind these are bare minimum and maximums).

Next double check your ram timings and voltage are manually are set in the BIOS run memtest (memtest.org) for 4-8 passes to ensure the memory is functioning properly.

Regards,
EVGA"

Anybody know of any AMP monitoring software.
