I installed daemon tools 3.41 on my windows xp o/s and it was working fine when i decided to raise the number of drives it was creating from 1 to 2. My system then rebooted out of nowhere, and every time i try to get back into windows, i get rebooted after 15-20 seconds. when i reboot, i notice that after ram checking, i have a new line appearing that wasnt there before - fixed disk: 0 IBM...(i dont remember the rest),i dont know if that has anything to do with it but i know it wasnt there before.
That line should be familiar to ya! Its your harddrive! You prolly just didnt pay attn to it before. Try booting into safemode, does that work?
