I had a fan problem with my vpc-z1190x laptop and when a repair shop tried to replace it, they fried the processor, which they replaced with a generic i7 motherboard. When software problems came, I am unable to use the recovery disks, because it sees the motherboard as the wrong system. Is there a Bios hack or work around that would enable me to utilize my windows 7 Pro recovery disks?
A different motherboard requires a fresh install of Windows from a Windows installation disc - - not recovery discs.
You can buy a genuine copy of Windows 7 with product key from Amazon if they still have any in stock.
When Windows is successfully installed and running, you can then download all the required drivers from the laptop maker's website which I assume is Sony in your case.
