Hi all,

I've got a Lenovo y510p that has been working fine for about a year and now suddenly I was having graphics issues in some games so I looked into it and Furmark shows only one card is working. One card is embedded in the machine and the other is an expansion bay card. Both are geforce 750m cards. I've tried updating the drivers but then I start seeing issues where SLI gets disabled and I have problems running the geforce control pannel or if it does run SLI options are missing until I roll back to 327.45. Any Ideas?
