Please help analyzing BCCode C2

[hyrobicera]

Recently I got a BSOD, and after that my pc won't start. The fans will start spinning but there is no power for the monitor, keyboard, and mouse, also the lan cable at the back is not lighting up. Tried to reseat the CMOS, press the power button for 1 minute, reseat/re plug all the cables. Unfortunately, I don't have spare pc or parts to test my hardware. I left the power cable unplugged and the cmos battery out overnight and tried to start the pc in the morning. It finally started and gave me these:

I just want to know what happened to prevent it from coming back. Thank you for all the help.

Update: Now I only want to watch a full screen online video then all of a sudden the power from the monitor mouse and keyboard are cut off, but the case is still lit up. Now it is not turning on again.

I would update the realtek network driver to the current version. old versions of this driver can cause errors that break streaming software, anti virus scanners and anything that uses the network IE bittorrent.
the errors can cause delays that lead to stack overflows.

you have several potential driver problems. if the realtek driver does not help, then you can remove some of the other drivers or update them. if you still get the problem then you could run cmd.exe as an admin
and run verifier.exe /standard /all
and reboot.
Note: be sure you know how to get into safe mode so you can turn off verifier if the reboot causes the system to bugcheck.
also note you have to turn off verifier after you are done testing via:
verifier.exe /reset
or your machine will run slowly until you run the command.

if you get a bugcheck with verifier on, it should name the driver that caused it in the memory dump file.

note: win32k.sys did not have a timestamp. it could be a modified version.


----------
basically there was stack corruption in a process owned by BitTorrent.exe
it could be a malware attack or a stack overflow

note: your bios verion is from 2014 but you are running old drivers that windows provided.
you should go to your motherboard vendors website and install the updated motherboard drivers.
mainly because of the USB specification changes in 2012 required a bios change and required updated usb drivers. you have the bios update but not the updated USB drivers so there will be various problems with your system that kind of build up while it runs and go away after a reboot. Best to update the motherboard drivers.

it also looks like the system is running the sata controller in ide mode rather than the faster AHCI mode. this happens when the system bios is reset to defaults on older motherboards. you can google "how to change disk controller from IDE to AHCI mode without reinstalling windows"

Okay, now my pc is back and running, I've cleaned the old thermal paste and re aaplied a new one and also changed ram slot. I've also remove the above unnecessary drivers and updated the the necessary ones. My pc is running on IDE because the BIOS settings is reset, I'll follow your instructions and set it to ahci again. I hope that this will be the solution for my problems. Thank you good sir!
