DREADED BLUE SCREEN

Ok so what's next from my black and blue foot, green face and NOW BLUE SCREEN. I don't know what is going on but some bad mojo or sumpin'? I finally had to do it.,.. I completely blanked out my hard drive and reinstalled everything from scratch. My computer has been acting up for some time now and thankfully I backup last month or so but now I lost modem drivers so no internet. I need to get a modem driver cd from the store and they do not open until tomorrow. I am using my daughters computer in the other room until then. wa wa wa. Not much else very cheerful to post. bleh.
