ok this past weekend my system (no brand/pieces parts) started locking up every 15-20 minutes and anywhere in between. reset-reboot good for another 15 minutes. any program seems to lock. its not a virus/spyware, not a heat issue. Its been touchy from day 1... its a Esc k7vza via chipset with a 850 AMD Thunderbird. from my findings/readings forums and stuff there seems to be issues with Via and Amd and certain manufacturers sound and vid and 4in1.... crappy drivers they all write. i found a latency patch that took care of my infinate sound loop problem/lockup for the last 3 years. now its locking at random. I got a new HD in box (pulled modem and soundcard out) with fresh 98SE.... still locks. I think MB is finally kicking it. Anyone running an AMD on intel chipset here? Whats your brand MB. I'm kinda partial to AMD.
