nope i haven't tryed any "safe mode" as you said, didnt though it could solve anything since normally, i dont need to boot under "safe mode" to install any appz
Yes it is the real BSoD

(is there fake ones? o.0)
yes there's some text on the BSoD but as i said before, its on the screen for up to 5sec at most >.< ... all i noticed was something like:
stop: 0x0000***
and i know that normally BSoD isnt solved by "buying" a full version of something

but well, my friend told me it solved his probs so i wanted to try, is it a wste of cash? only you will be able to tell but I do trust that you dont want to loose any customer
Tell me what you need to know and i'll do my best to answer your questions, looking forward for the next question...
