I joined just to let you know that this is not AMD/Via specific. I have gotten the same messages as you after a cold system crash on my rig. I have Pentium 930, 2x512MB DDR2-667 Geil dualchannel kit, eVGA 7800GT, Asus P5LD2 mainboard , WD2500JS 250GB HDD, and 550W PSU. It happens to me while watching DivX video (only if I use 6.x codec) and while playing Battlefront. It didn't happen on the same system with Pentium 630, all the rest being the same. Nothing is overclocked and nothing is crossing 60°C. MCA (machine check architecture) is designed to detect and report machine (hardware) errors such as bus errors, ECC errors, parity errors, cache errors, and TLB errors. Machine check exception (also called fault) is being generated when such an error occurs and the CPU must be reset in order to continue. When this exception happens, OS suspends any software running and records exception information from CPU MSR registers and then it crashes/reboots. It beats me what could be wrong with my computer though because I have used all branded components to put it together.
