The ntoskrnl.exe is the problematic driver in each BSOD occurence. How can I fix this?

Hi and welcome to SevenForums

ntoskrnl.exe is not the true cause of a crash.

Kindly follow the https://www.sevenforums.com/crashes-d...tructions.html to post your files so we can take a look at what's the real cause of the crash.

I attached the zip file. Also, I reformatted but it happened again.

RAM - Test with Memtest86+

Could you please carry out the memory test, one of the causes may be due to bad motherboard DIMM slots or bad RAM modules. Carry out the tutorial on each RAM module, and if an error is detected with the RAM module, test the same RAM module but in a different slot; keep repeating this process for all the RAM modules you have.

You will want to keep one RAM module in with each test.
