A little over a year ago I purchased a Lenovo Y500 series laptop. It contains two Nvidia Geforce 650m graphics cards with SLI support, which I was using for gaming. After a few months I began to have problems. Every few hours the graphics drivers would crash, giving me a "Display driver stopped responding and has recovered" error. This became more and more frequent until, after a particularly bad crash, my laptop would no longer detect one card, causing a serious drop in performance. Games would either crash on startup or they would run at ~10 fps or less, regardless of the fact that I was getting 60+ before on many of these games. I called customer support and it was determined that there was a hardware issue and so I sent it in to be repaired by Lenovo. It was returned good as new but after a month or so I began to have the exact same issues. This time, I brought it into a local PC repair shop, where they determined there was nothing wrong with my hardware. I managed to fix the problem again by using the Windows 8 refreshing feature, but again the problem arose. I eventually completely reformatted my computer but am still having the same issues.

I believe it is a driver issue, but I can't find any solution that works for more than a week. I have tried drivers from the Lenovo website, which didn't work, and recently I tried getting the latest from Nvidia, which did work but brought back the issues involving my display driver crashing repeatedly. Again my computer crashed mid game due to this and I had to shut it off manually. When I started it back up, one graphics card was again not being detected.

I'm really at the end of my rope here, I do not have the money to purchase a new computer and my warranty has run out. I should mention that these problems are not caused by Windows 8.1, since they appeared before that and I have installed the fix the Lenovo released for that specific issue.

Thank you for the quick response, I'll start using that guide.

Edit: Just removing the Nvidia software from my computer seems to have fixed it for now.

Well, both cards were detected temporarily, but I got the same error "Display driver has stop responding and has recovered" repeatedly, until my computer crashed and I had to reboot. One card isn't being detected again, Since then I tried installing a couple other drivers, including the latest driver from Nvidia and the driver listed on Lenovo's site, but no luck. I'm going to keep trying but this a recurring thing with every driver I have gotten to work, including the stock drivers.
