If I was in your shoes I would look at the following things: 

- See if dmesg or /var/log/messages reveal any clues. 
- Try booting the system with the noacpi kernel option at boot (you
  will have to modify GRUB's config files and/or add in the entry
  manually to do this.
- Related to the above, disable power management manually in the GUI

(I realize that I am describing these steps tersely, but if you need
help with these things then I am sure that me or others on the list
can help you find step-by-step guides.) 

My first guesses with weird problems like these are to look at
interrupt issues (especially when sound cards are concerned) and
things like ACPI. Sometimes the support for these things on older
hardware changes from kernel version to kernel version. 

A machine with 1.2GB of RAM should have no problems running Lucid, I
think.
