Lenovo Tninkpad 14 (E40) type 0578-A19: Update microcode

[babka]

So it's not microcode issue.

Thank you very much for your help! Tell me what could be the problem?  I’ll try to figure it out myself if you tell me what could be connected

Tell me what could be the problem? 

I don't know. Try to find information about this BSOD code.

A "Stop: 0x000000A5" error message typically indicates that the computer BIOS is incompatible with the Advanced Configuration and Power Interface (ACPI) standard that is supported in Windows 7. However, this error can also occur because the computer hardware, the peripherals, or the drivers for those devices are incompatible with Windows 7.

I'm just replaced the processor with i7 840QM and what could happen that it ceased to be bios ceased to be ACPI compatible?
It’s very strange why the bios determines so much RAM memory =) I'm don’t even have 64GB in my computer
