BC 124 is a hardware fault most probably caused by defective hardware

Here is my test raport, i think it's a RAM Memory, but if it is ram memory then PC wont start at all. I think that is the slots of RAM memory in Motherboard! What u think?

Well, before we go getting all crazy, the memory dump does indicate that the problem lies squarely in the L1 cache of the CPU:

1: kd> .bugcheck
Bugcheck code 00000124
Arguments 00000000 85ee1024 b2000000 00000175
 
1: kd> !errrec 85ee1024 
....
===============================================================================
Section 2     : x86/x64 MCA
-------------------------------------------------------------------------------
Descriptor    @ 85ee1134
Section       @ 85ee12bc
Offset        : 664
Length        : 264
Flags         : 0x00000000
Severity      : Fatal
Error         : [B]DCACHEL1_EVICT_ERR[/B] (Proc 1 Bank 1)
  Status      : 0xb200000000000175

In this case, the CPU is stating that the L1 cache on Proc 1 has failed, and the hardware should be replaced.

So the problem is on CPU? If i change the CPU then it will be everything normal?

 

[cluberti]

That's what the dump says.

 

[Leeo]

Well the PC can't be mistaken, can't he?
Thnx for the help, i will add u some rep
