This is my favorite XP service tweak site. They also have Windows 2000 service tweaks.
Nothing to report. Microsoft tech support know nothing. The guy i spoke didn't really know what Event Viewer was... This sure does look like an XP+AMD thing because i had the same problem with my Athlon Tbird 1200. At least everything is stable*. I still wanna know what this event is though. Last time i checked EventID had nothing useful. Googleing showed some infomation and also lead me here no too long ago. If i find out anything new i'll let everyone here know.
*I've run Prime95 while surfing, gaming, playing music, burning CDs etc and left Prime95 running for ~20 hours. I left 3Dmark 2001se and Prime95 running for six hours with no problems. I ran Memtest86 set to All Tests (takes 8-10 hours). So yeah, i think everything's stable.
