Hello, this is my first time post here.  I just recently purchased the GTX460 1024MB Superclocked EE card from newegg.  I've been having major problems with this card.  I have gotten rid of all of my old video drivers prior to installing this card.  When I installed this card and install the latest nvidia driver 258.96, I would always get a crash after I log on, and just freezes and hangs there at the Windows Welcome screen and will not go into my desktop. 

I have gone back into Windows safe mode and deleted the drivers and everything would be fine when I restart windows again with its generic drivers.  It is until I reinstall the drivers back again, that once it needs to restart the computer for the drivers to take into effect, it would just crash on the Welcome screen again.  I have done this countless times, I have even gone to make sure that all my drivers are deleted with a clean sweeper utility. 

The strange thing is when I have even gone as far as doing a fresh install of Windows, it would work fine the first day with the drivers and I would play SC2 or BFBC2 and it would work great.  I did however notice, that when windows did some updating to windows that this problem occurred again after reboot.  I have tried to uninstall all the updates that it did, but still get the same crashing.  I've been trying to debug this, it would occasionally throw me BSOD codes like Bccode 124 and 116.  Sometimes I get the occassional "Hyper Transport Sync Flood Error" during post.  I've gone and looked up what all these errors mean, but don't really understand them.  

I just switched back to my old 8800GTS, and this problem doesn't even happen with nvidia driver 258.96.  My case is very well ventilated, good airflow so no overheating has ever occurred.  Do I have a faulty card?  

Here are my specs:
AMD Phenom x4 955 BE
MSI 970FX-GD70 (Bios Rev 1.D)
G.Skill 2x2GB 1600Mhz Ram
Corsair 750HX PSU
Windows 7 Professoinal 64-bit
Antec 900 Case

I've updated my MOBO's Bios to the latest revision...still same problems...

It sounds like you're having the exact same problem I'm having.  My EVGA GTX 460 locks up at the Welcome screen.  I'm exhausted from trying to figure out the problem.  I'm on an AMD setup as well.

if you are running 64 bits W7 make sure you are running the 10.1 flash 64. go to flash support and uninstall the flash player with their tool that is provided, then install the correct flashplayer for the Os. the one on the main page is the 32bit version and will cause problems  even bsod..

I don't think Adobe even released a 64-bit Flash Player...

the 10.1 is the 64 bit version but to install flashplayer you have to install it in the 32bit version of your browser.. after you can switch back to 64 bits.. 10.1 was a beta for about 4 months to get it to work in W7 64 bits.. but it is still 32bits in the final release we are using now but 64bits capable, just install it in 32bit browser mode..and youll be fine..

Odd, this is exactly what started happening to me tonight. In my case, I can get into safe mode perfectly fine and do whatever I want to the drivers from there. That working for you still?

On the rare chance that I do get to the desktop, I'm finding it seems to work fine until 3D performance is required. General OS work (backups, installations, etc.) does just fine. Got it to crash instantly upon moving to the NVCPL tab with the 3D logo. Previous crashes were on Heaven and BC2 (but only once a 3D level started).

Looks to me like it's all in the drivers. Like with you, dropping my old 8800 in makes the system act like normal. The 460 runs fine without drivers as well (albeit at 800x600). The instant either Windows installs drivers or I manually add them, bam, problem's back. 'tis the strangest thing...

(and based on nvidias forums, some 480s and 465s are doing the same thing - install the driver and the system stops working)

Based on our three system (yours, mine and the OP's), I see only see one similarity - Windows 7 Pro 64, and that seems an odd thing to be causing the issue. We're not the only ones (seeing it on other forums), but it's seemingly rarer than the microstutter issue. I'm hoping the new drivers bound to come out and fix the microstutter fix this too. :/

I RMA'd mine to see if the new card fixes the problem...let us know when you guy's get your new cards if it solved the issue...

Hey guys,

This is the exact problems I was facing for the past 3 days.

The only similiar thing we have goin is indeed the Win7 64bit O/S.

I would 90% freeze/hang on the logon screen, but when sometimes I've gone to the desktop and whenever I started using apps that require graphics acceleration, I would hang.

:(

Win 7 Ultimate

.. and also I'm not using Evga, I happen to bump into this thread on the similiar issues u guys are facing. I'm using Galaxy GTX460 1GB.

Hi guys, I just got this problem today, tried everything, and then figured it was the videocard, googled the problem and realized I wasn't the only one with the problem.  I called to get an RMA. Hopefully it will work.  I also have windows 7 pro 64bit

Got no extra card to try it now sadly :(

This isn't happening just on EVGA brand only, it's all other brands as well with GTX460/480 processor on Win7 64bit.

Hi Ed, how is your card now? Mine is still having freezes after updating my latest MBios.

Hi, I'm having serious problems with this card as well. But it's part of a new build so I don't know if another part is malfunctioning. It hangs 80% of the time at the Welcome screen with the blue ring. If it gets to the desktop then it freezes at random. I've been having a lot of problems with the motherboard as well.
 
At one point, the system BSOD with the stated cause 'MEMORY_MANAGEMENT'. I ran memtest86+ and the RAM passed. I set the timings manually in BIOS and it seemed to work at first. But then the hanging returned.
 
I plan to try the suggestions posted in this thread, including installing Win 7 32-bit.
