How can I fix "STOP: 0x0000007B?"

Whenever I start my computer the regular way, a blue screen comes up and I can't do anything after. I have made a boot CD and I don't know what to do after. I was wondering if anybody could give me some advice, before I have to call up a tech...
Thanks in advance.

Take a look at this:
