Hello,
I think I've somehow solved it.
In msconfig, the boot tab, advanced, I've selected 2 cores and the amount of RAm that I have and .... no BSOD'd, 2 times in a row.
Until now I've done 2 Clean Boots with no BSOD's.
Tomorow morning I'm loading all the services.
I'll keep you posted.
Thank you,
Alex
