Just thought i would point out a few things after re-installing Vista Ultimate 64 Bit.
1. There has been alot of talk about Vista not re-installing correctly when you have more than 2gb of RAM installed.
I'm not sure if this is 'user specific' but i reinstalled last night with 4 x 1gb RAM in and all went well. Luck or not i don't know but it had no effect.
2. ABIT Airpace Wifi - There has also been problems with this on Vista 64 bit due to driver signing. I made sure i had this driver on my pen drive and installed immediately after the chipset drivers. This now works great aswell.
3. Make sure you have all the drivers on a pen drive before reinstall as it makes life ALOT easier.
4. If you use Windows Mail then export all the settings BEFORE reinstall. Save them and import afterwards. (saves alot of hassle).
5. If you have any mini images, make sure they are backed up aswell....save oodles of time when reinstalling your games and using Daemon Tools.
Sorry if this is 'teaching to suck eggs' but it helps me alot. From breaking my Raid array to being up and running was under 1hr 30mins.
