So I was on my pc earlier today, and all of a sudden the pc stopped working and the blue screen came up saying that Windows is searching for a problem on my computer. It has happened before, then I just restarted it in safe mode and it started working as usual. Now, i just get a BSOD when i try to start my pc and I cant even get to the windows login screen. I have tried all the methods I could find online to fix this, but I just cant get it right. I have tried every advanced troubleshooting option, and neither of them is working... It all leads to the BSOD and its saying Stopcode 0xc000021a. I have tried all the commands for the cmd and none of them are working. I tried bootrec /scanos and the commands like that, and it just said that 0 windows installations or something along that line was found. It seems like the pc can not find the windows files in my PC? I used the command E: and then hit enter and typed dir and hit enter again, and it showed me the maps Program Files, Program Files 64 and the Windows map, but it still can not find it? My pc knowledge is not the best, and I would really appreciate some help from you guys I need this PC to start working again without having to repair it, I do not have the money for that because I am a student and I have important files on that pc. Im sorry if my English is bad but I hope it is understandable.
