Hi and welcome. You've had a MCE stop error, aka 0x124 which means a hardware problems. Sometimes software incorrectly triggers theses, so lets take care of that first:
1) Navigate to C:\Windows\System32\drivers and delete this file:
PxHelp20 PxHelp20.sys Wed Mar 12 21:57:44 2008
Reboot.
2) Update your SiS Raid drivers:
SiSRaid2 SiSRaid2.sys Wed Sep 24 14:19:45 2008

I can't see most of your other drivers due to the way it crashed. If you have more crashes after doing the above, post them. But also include a screen shot of CPU-Z spd tab and also one of the memory tab.
