Hello there,
ive searched all over the web and still havent found a possible cure for this wretched BSOD,my pc was fine a couple of days ago till I disconnected an external hdd and shut off the pc since then ive been getting the 0XA bsod as soon as the loading windows appears,even in safe mode im unable to log in,checked the power and everything is fine on that end,my minidump files say its ntoskrnl.exe and i had made a seperate partition with windows on it from which i can access the bsod drive so i can find out whats exactly wrong and fix it from there.i dont want to format as it takes forever to reinstall all my programs for work.please help me figure this out

How to find and post your Minidump Files:

My Computer > C Drive > Windows Folder > Minidump Folder > Minidump Files.

It is these files that we need (not the folder). Attach to your next post the five most recent dumps. Notice the Manage Attachments button at the bottom when you go to post the next time. You can Zip up to five files per Zip; if you only have one or two you don’t need to zip them, just attach as is. Please do us a favor and don’t Zip each one individually.
