Acer 552-5686 always rebooting

Hi,

Yesterday I tried to do the erecovery with the 4 CD I did a while ago. Everything was fine until I put the last CD (4/4).
Nothing append with it. The timer was counting the time all the night but the % didn't change.

I was at 100% on the first line and 1% on the second line.
I tried to open the CD tray, change the CD, put the 4th back again but nothing.
I did a manual reboot by pressing the power button 5 sec.

I though everything was fine when I stat it... they ask me the language keaybord and everything else...
I saw the icon on the desktop and was even able to connect it to my wireless rooter.

THEN : the laptop just reboot by itself. And keep rebooting since. I can't even pass the windows lunch icon and I get this error message :

And after I got this blue screen :


I can run it in safe mode so I tried to go to the erecovery to run it again but it says I can't do it in safe mode so I have to do it in normal mode and they make me reboot but I can't run my laptop in normal mode.

I tried to press the ALT + F10 button on the startup with the CD #1 in the tray but this is what I got :



I don't know what to do now...
Can someone help me ?

Sorry for the misspelling but English is not my primary language
Thanks,
Mary
