To anyone that is having similar problems:
I'm almost convinced that this has something to do with my wireless adapter.
If my computer is in the living room (near the router) i do not experience any crashes.
If the computer is in the office (weak signal strength) I experience constant crashes.
If the computer is in the office but the wireless adapter is disabled I experience no crashes.
I'm using a Belkin F5D7000 wireless adapter with the standard drivers from windows update.
There isn't any 64Bit drivers available on the Belkin website;
"These drivers will install on 32 bit operating systems but not on 64 bit systems, which is the normal and expected behavior." ,
Guess i'm going to have to buy a new wireless adpater
