I have searched the Forum before posting this, it seems like different things happen to different users..anyway. About every 2-4 days I will have a Total System Freeze, it usually happens when I am surfing the web, every now & than I will wake up & find it frozen. The Event Viewer would always say True Vector Engine, ZoneAlarm.....well I got rid of ZA & went with Sygate Pro..still freezes. Event Viewer says nothing about Errors now, so I realized it only said True Vector because I had to shut off power to reboot (from being froze). Anyone have any idea what to look for next? XP Home 1.3GHz 512MB RAM This is a brand new computer (July 2002), came with XP installed. BTW-I went to Broadband Cable & added another 256RAM around Aug 2002. I don't remember freezing before that, I was on Dial-up, so it wasn't on as long.
