I'm suffering a very strange problem at the moment with my 460's, It seems about two or three times a week my computer boots. However it seems the drivers fail to load and i get the error message (code 43) stating that the device has reported a problem??
If i remove one card and restart all is well, if i then install the 2nd card and boot everything is fine!!! Then in a few days it does it again.. I have tested both cards on there own on another rig both fine. - furthermore, I have even removed the Overclock and they still do it!
However the trouble did seem to appear when i installed a PCI express wifi card (Edimax), i have changed the slot which the card was in however this has made no difference...
All graphics drivers are upto date along with the motherboard.
The only option i have left is to re-format and install a fresh copy of Win 7, Is it possible it's a IRQ issue?? anyone had anything similar?
I wonder if its from the PCIE wifi card running on the shared PCIE bus because each device you have on there slows it down because its shared. So i wonder if that pcie x1 slot is throwing it off by one on one of the cards perhaps? Just a guess, otherwise it could be one of the gfx cards went bad.
Nope not yet, I did update the drivers after the first time i got the error to 280.26. I was using 275.33, what version would you suggest me trying? I think i will re-format later today as a last ditch attempt before i spend any cash!
any luck? - i am having exactly the same problem but it doesn't seem to be caused by any particular card. they each run a-ok on their own - the second i switch sli on in the nvidia control panel it all goes wrong! tried re-installing windows last night, made naff all difference! Windows website is about as helpful as you would expect.
My system seems to have settled down now, i had to re-install windows take out the wifi card (Which i'm 100% sure was conflicting) however after that i still had the "This program has stopped responding" issue, which i seemed to have resolved by checking all the power cables and lowering my overclock on my CPU a little.
I'm still not 100% sure this has worked, however it has for one day at least!
I had the same problem on my computer.
The only way i got sli working was to add my old 9800GT as dedicated physx card.
It's strange, as everything works fine by themselves but when i enable sli without the 9800gt the driver stops working.
I have tried every old and new driver, reinstall and other setting in my bios. Have asked Gainward for support(all my cards are Gainward) but they haven't reply. Looks like i have a ghost in my computer
Think i have to get a lighter physxcard if i hvae to continue this, becouse my PSU is only rated at 750W.
