Ooooh...
bsod
We are, maybe, going to need a lot more system info and history from you !
1st, though...
Have you tried any
Safe Mode startups ?
Meaning, hit F8
just after your BIOS load stuff finishes...
Is it the true blue bsod with absolutely nada for info or do you get some white text on blue ? (Don't worry for now if the latter is the case but it all disappears before you can read it.)
Most bsod probs are from bad driver (.dll) installs.
You will... WILL get help here, so don't
PANIC ! 
btw... IMPORTANT btw..
Simply buying and trying to install the 'Pro' version is NOT an answer.
The problem is elsewhere so beware of the hope for quick fix€$
