My computer keeps crashing on me. All of a sudden everything stops working and the screen just freezes. I cannot do anything with it except reset it. I use Windows Xp Home addition. I've tried safe mode and it still does it so I assume it's not a harware conflict. I've tried reinstalling the OS, but it's just the same even before I've added any software that might be causing it. My ISP is broadband, could that be causing it? Any help would be very gratefully received.
