Thanks for the replies!
Follow-up to your Q's:
1) I originally loaded Win 2k Pro----I never had Win 98 on this PC.
2) I just put the PC together about 3 weeks ago.
3) My temp probe indicates the CPU is not overhheating.
(I have 3 case fans and two HD fans)
One observation, it tends to reboot at random; however, I've noticed it reboots more often when I hit "ENTER" to submit forum New Topics/Replies. I'm not sure if it's related to the rebooting issue, but it's an interesting observation.
Also, the error log reads as follows (I don't know how to interpret it):
Source - save dump
Event ID - 1001
The computer has rebooted from a bugcheck. The bugcheck was: 0x0000000a (0x7ffad000, 0x00000002, 0x00000001, 0x80496923). Microsoft Windows 2000 . A dump was saved in: C:\WINNT\Minidump\Mini091201-01.dmp.
Yep....this could be a fun one
