Been BSOD free for a couple days now.. leave PC on over night downloading stuff and all is good. I do find it really laggy, sometimes freezing. My PC used to be really fast, now its just getting annoying. In My Computer properties my PC had a 5.4 rating, the 5.4 is greyed out now. I go to refresh it, does the full system scan thing but right at the very end it something about a driver error and could not give a result.. can't remember exactly what it said but it did say something about a driver, but wasn't specific.
