Specs: HP Pavilion p6130y RAM: 8GB Chip: AMD Phenom X4 (Quad Core) Operating System: Windows 7 Home Premium 64-Bit (Upgrade) Problem Synopsis: Windows 7 Blue Screens when I do the following... Attempt to transfer files from one USB Hard Drive to Another Download more than one file (normally video files from about 100 - 200 MB) Restore iPhone from Backup I've tried TeraCopy and it does the same thing. I'd really looked forward to using this operating system but it just will not let go of this blue screen issue. This problem never existed with Windows Vista so I'm wondering if maybe I should go back to Vista altogether. At present, I've also had a problem with one of my flash drives. In going back and forth from my laptop (Windows Vista Home Premium 64-Bit) to my desktop post upgrade. I lost nearly everything in the drive itself. I'm also completely new to problems like this but I am willing to learn. I'll take any help I can get at this point.
