downgrading from windows 7?

yeah i got in a sticky situation... my laptop wont start normally anymore, its frozen on the loading screen and startup repair/ windows restore wont help it either...

i installed this driver in windows vista sp2 compatibility mode Original NVIDIA driver, during the installation process my latpop shutdown in the middle of it and becomes stuck on the loading screen. i want to keep windows 7 but my drivers dont offer it for windows 7 sony only offers drivers for my laptop in vista...

please help? should i install vista or is their a optional way to fix all of this with me keeping windows 7 and being able to install my gfx drivers?

I'll ask again: Did you change out the drivers given by the installer before you had a chance to test performance, or before optional Windows Updates provided the newer versions?

I am amazed at the number of people who think Win7 is like XP so they have to have their drivers all lined up in order to install as soon as the new Win7 install starts up.

This is not XP. MS spent a fortune paying to build drivers so they would be in the Win7 installer and quickly updated by optional Windows Updates. These are the drivers Win7 wants to operate, with rare exception.

Only if there are drivers missing after optional updates should you change out any drivers without having a performance reason to do so.

If you have done this then I would start over with install to wiped HD to get the cleanest slate: SSD / HDD : Optimize for Windows Reinstallation

My own tips for a perfect install, after hundreds of them: re-install windows 7
