I upgraded my PC to Windows 7 about two months ago, been fine but now getting issues which seem to be related to a problem with Windows drivers.
I tried to register online to get some support but it tells me it does not recognise my code. The odd thing is the code numbers I can see do not match the format they show as an example so mine is: 5letters/numbers-5letters/numbers-5letters/numbers-5letters/numbers-5letters/numbers.
Their example does not have that sort of product key.
The issue I am getting relates to Nvidia drivers which cannot be uninstalled or reinstalled. Windows will only load in safe mode, normal bootup results in frezzing after the logo or:
Stop: 0x000000116 nvlddmkm.sys
Another error code without a file was: 0x0000003B
