Hi, due to some installation of wrong driver , Device model number got changed from Vaio VPCEH25EN to VPCEH35EN. So very frequently I'm facing blue screen error. I tried installing fresh win 10 but restarting causing the same problem and VPCEH35EN Model . Please suggest how to revert back to VPCEH25EN.

1.Win 10 wasn't pre installed , device comes with win 7 pre installed.
2.Sony supports win 10 for my model.
3.As model number got changed ,which drivers to install whether Original VPCEH25EN Or As of now VPCEH35EN. now I am afraid to install drivers of Original actual model, as it may cause damage to system , eg BIOS.

And one more question , which driver software has caused model number changed. Bios or graphic or something else.so that I can rectify
