hi i need help since i installed win7 my graphics intergrated motherboard has started playing up alot and has no updates/upgrade for win 7 so been advised to go to win vista as motherboard can take that but i have no idear how to downgrade without losing everything??
As far as I know, you can't install any older OS over Windows 7. You'd have to do a clean install, and re-install every application.
Asus doesn't list Vista support for your p5vd2-mx se. It's based on an old Via chipset, and it looks like support for operating systems newer than XP is poor.
If you installed Windows 7 in such a way that a windows.old folder was created, you may be able to use that to restore the old OS. I eect that you'll lose everything installed since WIn7 was installed, but you ought to be able to back up files (not programs).
If not, I doubt that the downgrade rights for Win7 will be of much help. One, downgrade rights are aimed at industry, and I doubt that Microsoft supports them for individuals. Two, if you sold the Win7 license key to a friend, your Win7 installation is now in violation of your license agreement.
I don't recommend software piracy, but as you're already committing it after a fashion, you may as well go the rest of the way and pirate XP. Windows 2000 might be easier, as it doesn't require product activation, but it's probably less suitable for home use than XP.
