When using the PC sometimes out of know where the computer crashes and a blue screen appears saying some crap about an error. I will get a pic of it next time it happens. It happens at least once a day minimum. It has to be either a hardware or software program, I don't think it is hardware because i havn't really installed any new hardware but i have installed heaps of new software. I have installed Hijack this and done the spybot 2.0 scan heaps and it still blue screens and no virus or spyware or malware programs will stop it. Have any of you guys had this problem or know how i can fix it, apart from doing a backup of the whole PC and then re-installing windows XP and installing everything one by one and seeing what makes it crash. Doing it that way will take freaking ages because there's alot of info on the computer.
