Thanks for all the useful info, 
Asley! It's highly appreciated. Intel on the other hand... cannot e-mail them due to a bug in their e-mail form (tried from different PCs), cannot login to their support forum because of an login error. I'm kinda starting to take the hint they don't wanna be bothered. Atleast I'm smart enough to have another GFX in my private workstation, where C2 works like a charm. Better retire the laptop until I get hold on Intel. And Dell told me to reinstall OS, like they always do.
