My computer recovered from an unexpected shutdown

[Jubbi3]

I have had this problem with my computer for a few weeks and I don't know how to fix it, I'm playing a game and after a while it.. my computer just shuts down and restarts itself when I log back into my user it comes up with a window say "Windows has recovered after an unexpected shutdown" I look in the details and this is what I see -
Thing is I have been messing around with the computer and tried to fix it, by either trying to keep it cool and not get to hot but it still seems to not have any affect (BCCode: 124) is an overheat problem but my computer isn't getting that hot..
now when it crashes it goes to a bluescreen and says it has shutdown to prevent any damage.
I'm really confused.. any ideas?

Suggest 1) Reseat RAM 2) Run memtest to check RAM 3) Try repairing from install disk (taking care not to wipe the HDD!)
Also it's possible for the CPU or GPU to overheat without it being externally apparent.
Hope this helps.

Jubbi3,
Go to C:\windows\minidump. Minidump files have a .dmp extension. Select all the .dmp files, right-click sending the files to a compressed(zipped)folder. Upload that folder as a file here
