Problem:
WinXP pro was running real solid on my system for a couple of days. No problems. I installed a couple of programs and changed some users and configured IIS. I reboot and it POSTs and then black screen no activity. I reboot and it gets to chkdsk (had configured that too). Finsihes and then hangs. I try to boot to safe mode. Nothing. I try to reset to last known good. I tried repairing XP and then got a STOP unknown error c000021a. I install a parallel copy of xp and it boots into it without fail. I copy all my stuff off and then wipe and reinstall everything. Seems ok for a while and then starts having boot problems again. I have to double boot sometimes to make it work. This is from warm or cold boot too!
The plot thickens. I am now starting to find index and security descriptor errors in Norton Disk Doctor. When I "fix" them, my default login looses the password. The computer has started to auto reboot when trying to get into safe mode with networking when I have to reboot. It is still REAL intermittent. Sometimes it comes up like a champ, other times it comes up after two reboots. I am not getting any lockups or error screens while running the OS. It runs perfectly.
Known good:
All drivers are from Microsoft and current based on what the manufacturers sites say.
The p.s. supply voltages are 3.349 and 4.972.
My CPU temp is pretty consistent between 35 and 40.
I've disabled all hardware in BIOS, played with BIOS settings, removed CD/floppy, changed memory, used different video cards.
The hard drive performed without fail in another machine for months.
My suspects:
IIS, security, motherboard
Here is the gear:
ECS K7S5A
Athlon 1G (200)
(2) Crucial 256 DDR CAS2.5
ATI Xpert 2000
IBM 60GXP
LiteOn CD-ROM
Enermax 300W p.s.
Any and all help is greatly appreciated.
