Computer le broken!

Arh, so I have a Sony Vaio E series. Its generally really good.... However, I got home at lunch from school and it's stopped working. It went to repair itself, turned off, now just comes up with VAIO and a swirly loady thing and goes purple and the the lights are on and the cursor is there and the whole f2, f8, f12, 11 etc, etc won't work so arh. I have to use my reALLY old ancient laptop, and it stuffs up all the time and won't even turn on sometimes like the VAIO. I only bought it in December.
