I have Windows 7 Home, 64bit, 4 G of RAM, GTX 285, Intel Core 2 Quad I had recently installed trial version of Kapersky . I had an earlier message after trying to restart and a black screen with the message bad image sector or something like that. It started several times before. Now it will not start and I had to disable the automatic startup and I got the above messege. I cannot do the system restore because it just won't and I hear Kapersky sometimes prevents this. No detecable disk errors have been noted but it still will not even boot into safe mode. This process just keeps repeating and nothing seems to be helping. I had this message before when my screen flickered before but the computer kept running. It has restarted automatically before also but with no problems. My system will also, not restore to another check point. I am ready to reinstall windows.
