One error code is 0x8E and these are almost always caused by hardware though
sometimes by drivers. Nothing definitive was cited.
Your error is 0x124: WHEA_UNCORRECTABLE_ERROR and is described as "A fatal hardware error has occurred."
This error code and definition has replaced the older XP code 0x9C: MACHINE_CHECK_EXCEPTION and though it is older the definition still is applicable:
This is a hardware issue: an unrecoverable hardware error has occurred. The parameters have different meanings depending on what type of CPU you have but, while diagnostic, rarely lead to a clear solution. Most commonly it results from overheating, from failed hardware (RAM, CPU, hardware bus, power supply, etc.), or from pushing hardware beyond its capabilities (e.g., overclocking a CPU).
Honestly, this is a
very difficult error to work with because as it says a clear diagnosis rarely comes forth and I have never seen a minidump with either error codes give a definitive answer. I know IT techs that don't like working with it. What makes it so difficult is that it can be any hardware in your system -- and I mean
any. Your dump simply cited hardware as the issue and nothing more definitive.
Here are some of the causes that were determined to be the source of 0x124/0x9C errors from posters here and abroad: NIC, DVD/CD drives, dust build up around the CPU that caused overheating of said CPU, bulging capacitors hidden by heatsink, video card, psu, motherboard, and external harddrive connected by USB.

Did you update hardware drivers including your motherboard chipset drivers after you updated to W7?
