I just bought an Emachine 3256, have spent hours and hours transfering files and programs and all the stuff that you have to do when you get a new computer, I'm sure you all know. Anyway, it has been restarting on it's own for no reason. Once I was checking my email and that was it so I know it wasn't over worked. I have taken the machine back and had the hard drive switched out so I wouldn't have to do all that again. Now the new has done it 3 or 4 times. I have Spyware Blaster, have run adaware updated since the last time it happened and found nothing. Also have updated and run Norton, and have peerguardian running. Could it be unfortunately the hard drive? I thought maybe it was a power source problem but since it has happened on both machines, makes me think again. Could I really have to go through the pain that makes us all think twice about getting a new computer again. Any ideas? PLEASE!!
