Windows 7 Ultimate hangs on Starting Windows

Hi all,

I have Sony Vaio VGN-FX21M.

I have/had install Windows 7 Ultimate and the machine worked perfectly.

Yesterday, the laptop went into sleep mode like it does and when trying to revive it (Usually by pressing a button or the power button) it turns back on.

The system appeared to turn on but the screen would not and I sat there for 30 mins with no response.

I did a hard restart (Hold power button) and when the first screen loaded some of the logo is distorted, it then changes to a screen full of open brackets and then finally trys to load.

I get the spining balls and then the windows flag appears and that it. Also on the page dark blue lines run vertically on the screen in groups of 5, seperated by a small black gap before it appears again.

I have a recovery disk, but it's not loading properly... can someone tell me what I can do as I am a complete novice!!
