Norton Utilities crashes Windows 7 after Registry defrag. Blue Screen of death even in safe mode

Hey everyone,

 

so yesterday I did a registery defrag. with Norton Utilites premiere. And when I reboot I get the blue screen of death (just before I can log in)

 

picture of it :

 

 

I am running a Windows 7 64-Bits.

 

Starting the computer in safe mode, using startup repair, system restore etc. will not work. (safe mode = blue screen)

 

 

 

Ive searched the forum and saw lotsss of thread with the same problem as me but I never found an answer. When they was one, it wasen't working for me. It is my work computer I need it asap!!!

 

I do not have a CD for windows 7 (but i still have my CD-key)

 

 

could anyone help me? thx
