So i got a friend a new motherboard since his old one got fried, And now his GPU is randomly crashing with any game
He formatted his computer, reinstalled windows and the issue persist ( crashes when doing a single benchmark run with rainbow six siege, or within 5 minutes in the game )
What did help a [B]TON[/B] was using DDU in safe mode to remove the nvidia drivers and install the version he had before his the old mobo died . The issue still happens but it takes longer to occur ( now it occurs within 1 hour of gaming )
Installed and updated directx and again it works much better now ( takes arround 2 hours for it to randomly crash ) . Still im clueless why its still happening, we even ran it trough furmark for 10 minutes of course keeping an eye on temps and they were perfect
Well the first suggestion would be to swap it for a another gpu or use the integrated one.
My 660 is usually stable but will do a TDR freeze on a random game sometimes, so my bet is on the gpu being faulty, but that's mostly because of the shitty nvidia drivers and being 4 years old now.
It's probably driver incompatibility + faulty hardware specifically on the 660.
I had a 660 TI for a couple of years, and ever since the 900 series came out, graphics card crashes became more and more frequent. At first it only happened in 1-2 games out of all games I played, then it started spreading towards most games I played.
Seems to be a common issue with the 660 and 660 TI specifically. While trying to troubleshoot the problem, I found many similar stories online.
Also, it seems to be related to power draw, I believe. The first games it started happening in to me had nothing in common in terms of VRAM, but they were all optimized in terms of shaders.
Overvolting your graphics card (as well as underclocking the shader clock) can reduce this problem greatly in the short term.
Aww man. I have had similar woes on GTX470. Problem is, that if you compare the date at which 660 was released and today, you notice that the card is quite old. This is a problem with nVidia. There are even stories of how new drivers that nVidia pushes burn cards out on purpose.
Anyways, here's what I can tell you from my experience:
Everyone says "update your drivers", "update DirectX", make sure that the power is secure, underclock it with afterburner, fresh install of OS - All placebo fixes.
The [i]BEST[/i] that you can do at this point is the opposite of the common suggestion: ask your friend to install an [b]old[/b] version of the driver. A version that he remembers worked back in the day when the card didn't have this problem. If it continues to crash, then all I can say is this: something is fried. The card will never be able to run without crashing in some games :(
Either the card got damaged from "natural causes" or the spooky bed time story variant of him installing a newer nVidia driver, which intentionally fried a shader unit, tripped some efuse, etc.

After extensive digging, I remember stumbling upon the dreaded text that I feared to see. Go to Event Viewer (if you're on Windows), find the display driver crash, click on all the details. Amongst all the garb, you might see some text that can give you an idea of what's going on. Mine kept saying shader unit and the same exact number. That was most likely a fried shader unit.

Bottom line: the days of using your amazing 6600GT for nearly a decade are over :(
GPUs these days have by orders of 10 more components, smaller sizes, production scales going up (quality decreasing). And nVidia wants you to upgrade >;)
But I could be wrong. You should totally still re-insert the GPU, make sure the PSU is good, power connections, try different PCIe port, etc. Don't throw the card away for no reason!
That's true, downgrading your driver is the best fix possible for this issue.
I personally couldn't downgrade due to a microstuttering problem I had in a certain game, which the newer driver fixed.
I'd rather suffer any kind of trouble, even killing the card completely, than to have to deal with microstutters. It's the worst type of performance issue one can experience.
So slight update on the issue
I swapped his GPU with mine (GTX 970 TI ) And it ran perfectly, with every single game, then i tried HIS gpu on my computer and it ran perfectly!, No crashes at all, so i put his GPU back into his computer and the crashes have returned, for some reason it really doesnt like working with his GPU at all...
If it helps any i went to the windows event log and it shows 2 error within the same hour as Kernel Power Error
