I would look to see if the CPU fan is working at full speed, clean out any dust. I think your CPU overheats and causes bugchecks
with older machines the overheating can be with the memory controller attached to the CPU on the motherboard. Put a fan on the system and see if the problem still occurs.

Note: these old systems tend to have solder that is brittle and cracks causing circuit connections that connect and disconnect as the system heats up.
Really hard to find these problems.
I would start by checking temps and the CPU fans. I would also boot and run memtest86 to confirm the basic memory system is ok.
if that is ok, then try setting some verifier flags to look for a driver that is corrupting memory.
on windows 7 you would start cmd.exe as an admin, then run
verifier.exe /standard /all
and reboot
and wait for the next bugcheck. (sorry, in vista days I had my own program to set the flags so not sure if the current method will work)
Note after you are done testing turn off the verifier flags or your machine will run slowly until you do.
try
verifier.exe /reset
-------------
looking at the bugcheck, most current first:
first bugcheck was cause because something corrupted kernel memory belonging to the system.
second bugchek was bugcheck 0x124 called by the CPU
system was up 5 mins, most likely the CPU reset because of overheating.
third bugcheck was caused because the memory image of csrss.exe was corrupted(modified) in memory, the system detected the change and shut down.
forth bugcheck was 0x124 called by the cpu, system was up 4 mins 34 seconds. Likely the cpu was reset because of overheating.
