Help me please!!

So I've had a homebuilt system (built by a friend) for about 6/7 months now and in that time, I've upgraded from Vista to Windows 7. What I'm looking at doing is a "Restore to Factory settings" because the system is running quite slow (I've backed up everything of interest and just want to start fresh with this computer again). Will this put me back onto Vista as it was when first installed or will it put me back to when I first upgraded to W7?

Thanks in advance!

I dont know the answer, but do you have the vista OS disk with a license on it?? if so, and your all backed up to another drive you can format your os drive and reload vista and start fresh. I wonder why it runs slower. Must be driver related?? did you check for a bios update for your MB? Or search google for win7 issues with your specific MB. You might be able to save this without reloading vista. I would list your MB model and bios version as well win7 version. One of the experts here might answer your question if they have enough info.
Good Luck

It's an upgrade disk. Looks like i'm going to have to do it the long way =(

Thanks for the answer!

If its running slow have you thought of just removing the virus? Seems to me to be a lot easier, depending on what your infected with that is.
