On a shared Windows 7 laptop, I turned it on and it boots normally then a couple of seconds after my home screen comes on it goes to a white screen and the only thing I can do is ctrl+alt+del and restart/sleep mode/hibernate/shutdown. All other options lead right back to white screen. Even booting in safe mode and safe mode with networking do the same thing. The only options that work is safe mode with command prompt or advanced boot options from BIOS +f8. On start up my computer does run an automatic check disk operation and that has run but nothing else. I have a FRST scan result and have not done anything else. Any help would be appreciated!
