Okay... I am just one opinion, but I think an in place reinstall has it's ups and downs.... the ups is it'll probably fix the problem, the downs is all of your old hardware will still be in there causing trouble. So you can get some other opinions/ideas on that one. But as shifty as Microshaft can be I doubt they'd blue screen you for changing your hardware... It'd most likely be a message of some sort telling you to contact them, and mentioning that piracy is illegal ( gotta love M$) But, you never really know with these things...... One question though.... did you register with Microsoft? Because if so then it very well maybe the new hardware detection and their interlinked paranoia software stopping you from booting. Once again I doubt they'd use a blue screen though.... serious lack of professionalism, they'd take alot of crap for that, plus it's seriously confuse the average user who isn't aware of their paranoia software.
