Windows 7 RC 1
I wanted to update my Vista system in the living room (Medion MD 8818) to Win 7 RC 1. But I encountered a nasty error: the RC version doesn’t seem to work with nVidia chipsets. I tried the following:
- boot old Vista, install Win 7 RC using upgrade mode
- boot old Vista, install Win 7 RC using clean install mode
Both resulting in a BSOD (0x124, 0x4, see here: http://msdn.microsoft.com/en-us/library/bb725851.aspx) concerning PCIe.
Booting from the install DVD results in a black screen – just in the moment the installation screen would appear (after the blinking Window logo on black ground).
So I googled my way and found the following hints:
I changed the graphic card from the Medion one (some nVidia 7xxx type AFAIK) to a 7500 one (also from nVidia. Same symptoms. So I bought a new graphic card from nVidia (low end, some 8xxx type), same symptoms.
Finally I bought an ATI card (EAH4650) – and the BSOD went away, and the installation routine continues. Hopefully I’ll be able to swap back the original Medion nVidia card (no fan ). Time will tell.
It’s very strange that MS managed to spoil the RC version of Win7 concerning nVidia cards …
