Alright, I'm going to try and make this short: Bought some pieces, assembled a new PC, installed Windows 7 Ultimate, then SP1, then several programs and everything seemed to be fine. But the next day, without changing anything, some programs won't start correctly, to be more precise: their proccesses seem to start (or at least they show up on Task Manager, but consuming only a few KB of ram and no CPU) but no program window appears whatsoever. Sometimes rebooting the PC will stop this from happening, but not always. Here I attach screenshots of CPU-Z and the customary files for debugging BSODs (I wasn't sure what data to give you guys, so I defaulted to this, as it should be pretty much complete, if you need anything else just ask).
