Cool_Hand,
All the info gives us a good understanding of what is going on in your computer.
I would like to try something. First I would like to pull out the ATI card and any other PCI Cards you have in the computer. I want to see if it still locks up on you.
WinME does not like legacy devices or legacy drivers. There were many problems between SoundBlaster and WinME, since SoundBlaster includes Legacy Drivers in their Driver Package.
If you could I would like to see a list of all your IRQs and every device on each IRQ.
Take Care,
Richard
