I am still having the instability problem wherein I have to jiggle
power connector sometimes to get my machines to boot.

I re-configured my AMD machine so that right now I have:

Primary Master - Seagate Barracuda 120GB ST31200026A
Primary Slave - TSST CORP DVDW TS
Secondary Master - WDC WD1600JB-00GVC0
Secondary Slave - MAXTOR 60GB 6Y060L0

This is the way I really want to run this machine.
I have activated all fans so that now I have two case fans running
plus the CPU and PSU fans. I have enclosed the tower.

I am still having the instability, and now I even find that the third
HDD I added is showing problems. When I first boot, BIOS identifies
the Maxtor as a 'CALYPSO', and after I reach the WXP desktop, and look
at MyComputer, I find that neither HDD on the secondary IDE is
detected by XP, If I immediately shut down/restart - the BIOS
correctly identifies all the HDDs and MyComputer shows all HDDs.
Go figure!
