Your error is 0x124: WHEA_UNCORRECTABLE_ERROR (Windows Hardware Error Architecture) and the minidump gave no definitive probable cause.
This bug check indicates that a fatal hardware error has occurred.
Straight up this is a
very difficult error to work with because it can be due to
any hardware you have. The old error code under XP is 0x9C and its definition will help you understand the error.
0x0000009C: MACHINE_CHECK_EXCEPTION
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).
I have seen the cause in both 0x124 and 0x9C due to the cpu, overclocking, cables, NIC cards, CD/DVD drives, motherboad, and harddrives. Someone had just posted earlier this week after receiving an 0x9C error that it was due to dust build up around his cpu.
The best thing you can do that this moment is standard diagnostics:
1. Run memtest on your memory for a
minimum of 7 Passes. See this link:

2. Run a harddrive diagnostics. Your HD manufacturer will have a free utility to do this.
