If you want to completely reinstall Vista, to factory defaults...

First, if you created backup disks when you first purchased the computer, you could use those.

Second, i'm not certain if this will work on this specific model, or after the changes you made, but there MIGHT still be a backup partition on your hard drive:

to TRY reseting to factory defaults from the hard drive, press alt-f10 when you first turn on the computer, and hold it down until a recovery screen comes up.   I don't know if that will work or not.

Third: you can order a recovery CD from Acer here:
