Hi Pulkit_Valecha: Thank you very much for joining the Intel® Graphics communities.
In order to try to fix the problem we can try to re-install the chipset driver, I looked for it but there are different versions for Y700, on the link below you will be able to download it:
If the problem remains after that then we recommend to get in contact with Lenovo directly for further technical or warranty assistance, they might have additional steps to try in order to resolve the problem:
Any further questions, please let me know.
