Hello everybody, this is my first post in this forum. I have been getting BSOD in my laptop (HP dv9000) since yesterday whenever I boot my system. I have both Windows XP and Windows Vista installed in the same machine. This combination has been working fine for me for approximately last two months. SInce yesterday whenever I try to boot my system using Vista, I get vertical blue lines in from the very beginning and then it crashes with blue screen. Same problem for win Xp too. No I am only able to go through safe mode only. Please help. I have attached the minidump files from my Vista partition.
