It will be easier for someone to help you if you describe the problem. Just saying there is an issue is not enough for anyone to fix it.
 
I am guessing from your last that it is an SLI issue, but it's not clear.

Here is yesterdays 295.51 driver release progression

Driver failure
http://forums.evga.com/fb.ashx?m=1438000

Here is a in-depth technical description of the exact failure noted
 
 
Nvidia driver 295.51 downloaded to my desktop
Afterburner settings changed to "not start at windows boot" (to prevent wrapper failure on reboot) and shutdown. 
*cards 100% at stock settings, only custom a fan profile used.
 
Fresh reboot to desktop
 
Start/Control panel/Programs and features
Nvidia entires showing:  Graphics Driver 285.79 and its PhysX version 
PhysX uninstalled normally
Graphics Driver uninstalled normally
Restart selected normally
 
Reboot into windows
Normal (no driver installed) reboot into windows
Normal "Standard VGA adaptor" installed on GPU 1 and "Failure to install Standard VGA adaptor" on GPU 2
Normal "restart requested" by windows, ignored and closed.
Nvidia 295.51 installer launched
Unpacked to default location, installed with "Custom Option" only Graphics driver, PhysX and Clean install checked.
Normal install noted, restart selected
 
Normal boot to desktop noted
Nvidia control panel in right click desktop flyout shown
Nvidia control panel used to enable SLI
SLI enabled normally
Nvidia control panel used to set my standard NVCP settings (3D settings)
Changed: Frames to render ahead from default of (3) to a value of (2) and set to "single display performance mode)
No other NVCP settings cahnged
Display properties used to confirm screen res and default refresh rate (no changes made)
 
Afterburner re-enabled and re-set to start with windows
 
Computer restarted (rebooted normally)
 
Appox 2hr of browser use, posting/reading viewing videos (normal, no issues seen thru maybe 15 websites)
 
Knowing I wanted to do testing later that night with benchmarks and BF3, and that there was a patch for BF3 pending..
I again restarted my computer (normal boot, no issues seen)
Opened Origin/Battlelog (left at idle for 10mins in case of backdoor updates to punkbuster or game), then got link for new browser plugin, shut down Battlelog then Origin and installed the new plugin.
Went back to browsing and posting for appox 1hr.
Then a Full system shutdown (for dinner)
 
Upon startup, normal booting behavior seen until the windows Logo screen
*Noticed right away the "green pixel" in the top lefthand section of the Logo screen that occurs when a driver is not loaded.
System appeared to "hang" on the windows logo, and the "login chime" was heard while still on the logo screen.
Typing in the Admin password had no effect and a power button full shutdown was needed.
 
Upon reboot, Windows booted normally but without a driver and I got a single Standard VGA adaptor install notice of failure, but no reboot was requested...
Afterburner gave normal notice that no driver was detected
Start/Control panel/Programs and features
Afterburner was uninstalled
Nvidia entires showing:  Graphics Driver 295.51 and its PhysX version seen
PhysX uninstalled normally
Graphics Driver uninstalled normally
Restart selected normally
 
Normal boot to the desktop without a driver was seen
I used my normal process and re-installed my previous 285.79
All normal steps with the driver and Afterburner were taken
Tested lastnight with 2 passes Heaven and one of 3Dmark11 -and- 4hrs of solid BF3 play.
 
Attempted another 295.51 install this morning using the exact same steps
Driver installed, SLI enabled and NVCP setup and Afterburner same as before.
Hot restarts showed no problems
A full shutdown and cold restart showed the same hang at the Windows logo screen as before.
 
All the same steps taken as before to re-install 285.79
 
Everything is currently working correctly (with 285.79) and is what I am using now 
 
 
  

Time to reformat mabey ??

Can you install 295.51 driver, then send me a mail at jacobf@evga.com
 
I have a file to send you that will spit out a log file then can you send that back to me.

Well, at the risk of angering a few. This doesn't seem to be widespread. I did my usual simple clean install over the previous BETA. Runs fine. No glitches. Ran Batman AC for while. Seemed normal enough. I'm running SLI 580's with a dedicated 470 for PhysX. In a nut shell what you're saying is after a few reboots, SLI disables itself right? Is this just on one system? Now personally when one person or only a few are having issues over repeated driver sets they may just need to take a look at their system. What is in your system or what have you changed that is non-standard? When is the last time you did a clean OS install? You may have a corrupted driver store/registry or a service that isn't running correctly.

Thank you bro for your input (which I value highly)

If you remember, when I had problems with 290.36?
I did a full OS reinstall after that and still had the no SLI option available.

The issue has now progressed in this latest release, to full Nvidia driver failure to install on a cold boot.
*it is unknown if the previous drivers also had this cold boot issue, as I never bothered to do full testing once I saw I could not enable SLI

Strange issue. Have you swapped the cards around? I had one 470 (out of 3) which would not run in SLI properly if it was in the first PCIe slot. I had to mark it to make sure it wasn't in the first slot or SLI wouldn't work. Slot 2 or 3 it was fine. The other question is, I know you disable some services on your installs. Have you considered re-enbling them for testing? And lastly by 'clean OS install' are you doing this from a backup or actually doing a virgin install from a Win 7 disk?

Virgin OS reinstall, and 290.36 install was done before I made my normal changes to my processes and services list.
 
No, I have not switched my cards....
Dont see how that would have any effect, as both cards have the exact same default VID and have functioned normally with the last 10 diversets leading up to the first problems starting with 290.36
 
At this point I am ready to do whatever it takes, and I run a dual boot system so its no big deal to reinstall and do serious work on this problem. I am really open to anything and have the time and desire to do whatever it takes

Maniacvvv, why don't you try the nVidia recommended method and just run the installer and overwrite existing drivers? That's what I always do (couldn't be bothered with "ultimate driver install guides") and never had any problems...
 

Have you tried removing Afterburner and leaving it off while testing?
 
Also, I know this may seem unrelated, but have you ran a chkdsk /r on your windows drive? I bring this up as there could be something corrupting the drivers, and a failing HDD can do just that.

Thats what HeavyHemi suggested.... I will be trying that today, along with about 10 other things as well

"tested monthly" and no offence, but since I don't know what/how you test them, I'm inclined to take that comment w/ a grain or two of salt..
Have you ran chkdsk /r on the drives since your current run at the problem?

No chkdsk, I use HD Tune for health checks and performance monitoring on my platters, as well as Perfect disk for defragging
 
I do alot of Video production stuff on my rig, and HD health is critical... I learned that lesson the hard way years ago... all my drives are checked regularly, if one is starting to show any errors, I dump it and get another one.

ok, the version of HD Tune i have doesn't look for file system errors, granted mines pretty old, so based off that, run the chkdsk /r on the drive, it will find the things that HD tune doesnt look for (as in NTFS file system errors)
running it from your SSD on your platter drive might be the easiest. you do that by running the following from a command prompt "chkdsk #: /r" where # is the drive letter of your platter drive with windows on it.

Since the new installer i was advised to turn off Afterburner/Precision then install,ive never been told to restart after install by the installer .Ive had no problems even when doing SLI 480's . Sorry this is happening but i guess i have to ask is either program running on install ?
