Majority of your crashes are 0x124 bugchecks, yes. These are caused by WHEA (Windows Hardware Error Architecture) triggering due to a hardware fault. If you wanna know how to interpret them, you'll need to grab Debugging Tools for Windows (aka WinDBG, from the Windows WDK) and then run the
!errrec command followed by the memory address mentioned in the second argument for the bugcheck. The 4 numbers after the crash error code (0x124) are the 4 arguments. Doing that will bring all the results from the WHEA error structure telling you details on what went wrong. Example below:

Error : Internal timer (Proc 0 Bank 5)
Status : 0xbe00000000800400
Address : 0x000007fef6d51519
Misc. : 0x0000000000000000 Every 0x124 crash I've found from you are the same issue. An internal CPU timer failed. While almost every time it's during Processor 0 (that's the first - and primary - CPU core) activity, every time it's also using the same CPU cache bank (Bank 5). Very consistent behavior.
Before we start blaming the CPU on this, first you should go to the Sony website and download and update both your BIOS and any and all
drivers for your motherboard. Typically they show up as chipset or CPU drivers. If none of that fixes the problem, then we will have to believe that the CPU has failed and you will have to replace the laptop or get it serviced if it's still under warranty.
