Mine is an AMD Athlon 800 MHz processor on a ASUS A7v+ mother board with 512 MB Ram, 4 80G HDs and ADAPTEC 2490 SCSI bus with CD Burner and flatbed scanner. The Video is a 64M NVIDIA Based Card. The Machine locks only in the GL driven screen savers and only randomly but does lock hard like with you guys but I am also noticing what I can best describe as a stutter in the CPU about every 30 to 40 seconds when in GL based games like UT2003 or Lbreakout. Perhaps it is related somehow to the GL section of the kernel? I am not a code head (but I wish I was) so I really don't know. :) Ron
