Recovery CD wont go past 99%

I have a Compaq Cq50-215NR. My daughter had severely cluttered it up, so I put in the restore CD to restore to factory condition. It completes to 99% and wont go any further. No error message or anything. Just 5 minutes remaining at 99%. I have left it go for 30 minutes and nothing. Now I have nothing on my computer. I start it and just get a blinking cursor. Any solutions?:frowning:
