Particularly Intel drivers for x86 are known to be a problem (I can confirm this) because even if they know perfectly well how to make drivers for x64 (using all available memory), I guess they as a MS partner make on purpose x86 drivers having issues when you use more than 4 GB of RAM in x86, just to help MS pushing x64 systems.
So make an image of system before installing any driver, latter go one by one when you install drivers and reboot after each one to detect any incompatible driver.
hi alacran,
have you experimented with early XP version before SP1? Im having trouble finding any XP prior to SP2.
thanks
