Its seen sometimes that while editing the boot drives using partitioning softwares, errors may occur..So my first suggestion is to reinstall XP. Also, try re-inserting (means remove the ram, insert the same again) the ram. And abt the BSOD, its quite natural..u may cant read all those stuffs, before the system restarts.. If u r reinstalling XP, then delete the full partitions using the xp partioning utility (during installation) then create a new one. For xp u need only 4.5 GB. But make sure that u install program files on ur other drive..
PM me for further queries..
Regards.
