Ya, exact same problem, it has happened to me before.
I am screwing around on the net, watching a movie w/e then out no where the computer stops working, everything stops responding then I get the blue screen telling me windows is shutting down to save my computer. I turn the comp back on and the Chkds or w/e runs, deletes files and what not, then the loading screen followed by a black screen with a mouse pointer...
Please help...safe mode does NOT work, none of the boot options nothing.
It is a new comp...an Insipron 1525 Special Edition.
Seriously if Microsoft is going to make an OS at least have them make it right ffs...
