My computer freezes after 5 seconds on the login screen

[callesen58]

I haven't installed any new hardware or software, the only thing i did was move my computer from one place to another.

Safe-mode also doesn't work since my computer wont recognize any button on my G15  computer when i try to select boot options.

Edit:

I'm using XP and Avast.

Toshiba G15?
Do you have Windows CD?
