Re: 'Tuti Fruiti' on cold boot
I wouldn't suggest RAID 0 in the first place, but what happens is parts of files and programs are on both drives. So RAID 0 offers the ability to access files a bit faster.
Since you've already uninstalled the program, try running some disk checking software to make sure your hard drive isn't failing. I would first run a disk cleanup, then disk defrag, and finally a disk check (checking all sectors which actually required a reboot, and it will check the drive at restart).
See if it comes up with any errors.
