Windows 7 Strange freezes when games are loading

[gost]

I'm experiencing strange freezes when a game is running. I have tried to recreate this problem by putting load on the HD's, ram or network but with no luck.
See system specs and dxdiag on attachements.
Games tried is Brood war and Dungeons and Dragons online. Both games have worked before without flawes. I would have tried other games as well but have access to no other games at the moment.

Been reading the other posts in the forums and lots of people seems to have similar problems but none that describes the problem i have.

Thanks for the help in advance
