I'm a computer novice. I downloaded an update to my internet security software. I rebooted the computer as instructed. (I have Win98.) Upon rebooting, just before I am supposed to get to the network logon screen, the computer freezes. The fans stop working. The yellow light that indicates activity stops. No noise. Nothing. It does the same thing in safe mode. The company that makes the internet security product says they can't help me. I have limited resources but am willing to fix this myself. Can anyone help me? I'm on my mother-in-law's computer away from home.
