Does installing Windows 7 interfere with the motherboard bios settings

[wireoffcut]

Hi. I'm just wondering if Windows 7 has altered my motherboard's bios?  I'm asking this because I have a Asus P5e3 WS Pro motherboard, which can only support Windows operating system up to Vista. I didn't know this when I installed Windows 7 onto it.  Fed up with getting the blue screen error, when trying to reinstall Windows XP on it again, I zero wiped the drives, and reformatted them again. But even so I'm still getting the same blue error screen when I attempt to reinstall Windows XP again.
So I'm wondering if when I installed Windows 7, that it wrote something to the motherboard's bios to prevent any future system downgrading.

An OS cannot and will not write/change anything in the BIOS...
I run Win7 on a P5 ASUS MBoard with zero issues...Vista on the 2nd HDD.

Post the entire BSOD including the gibberish...

Did you happen to make any changes to the BIOS ? ?

Not sure where that info came from...all the documentation i read mentions nothing about it not being able to run Win7.
It would be silly for a MBoard manuf to limit the board to OS's.
