Why not tell us all you can about that blue screen, such as the error number. Just booting again probably shows it again (if it doesn't your problem solved itself!).
And can you provide a few links to the solutions you found that said the issue was caused by files on the hard disk? By the way, I'm sure you had some files on the hard disk. It can't be totally empty, it should contain Windows at least.
Why are you desperate about formatting (or, better said, doing a system recovery back to factory conditions?
I own a VAIO laptop VPCEA25FG series, with Core i3 2.27 GHz , 4GB RAM , ATI Radeon 5145 , and 64 bit Home Premium
I accidentally unplug my laptop AC adaptor and since I don't plug my battery on my laptop , it shuts down automatically and since then I am very sleepy , so I am lazy to open my laptop . I left it there and tomorrow morning when I opened it , the VAIO screen appears , Windows boot screen appears , and finally when the boot screen is finished , it flashes to a sudden blue screen and my laptop automatically restarts . I disable automatic reboot on crash (or sth. like that) and I read the blue screen...I forgot the texts , but the point is I searched the solution for this and I found most of them are caused by files in the hard disk . Mine didn't have any file written on it . So , I asked my friend and he said that's because of system crash....and he said I should format it !
Please help me !!! I am desperate .
