You have had a bluescreen crash bugcheck 0×3B which is forced on x64 Windows platforms when an exception happens during a system service , pos Vcore or voltage instability, then two bugcheck 0x101 errors which is CPU or other hardware like mobo, This happens when the processor is either dead (doubt it) or it is deadlocked - by resource contention. This is usually caused by a driver having an exclusive hold on an object when another needs it and waits. you now have fully up to date drivers, updated your BIOS and changed to another antivirus and now your latest crash is a bugcheck 0x124 which are hardware problems- compatibility issues (hardware or driver)- corrupted driver. The error which is WHEA_UNCORRECTABLE_ERROR (124) would suggest video card to me ? but debugger also states All of the clues point to a hardware component failing and this could be a motherboard fault , CPU or ram ? please make sure driver verifier is turned off by clicking Start, then Run, and type verifier /reset in the Open box. Please can you run >> prime95 << and let us know how your system responds ?
