pc won't boot error code 0x000021A

[TrinitySMQA]

Hey guys!
need some help, my pc won't boot, a couple of days ago when i played starcraft 2 the pc just randomly shut down and then when i tried rebooting, the power turned on for about 1 sec and then powered of, after a few seconds the pc turned itself back on or 1 sec and then back off. contiously doing this until i turned off the power, after i waited about 15 sec and tried turning it on again and it worked no problems.

until yesterday when i tried playing SC2 again, a couple of minutes in my pc turned off again, and wouldn't boot in the same maner as before. whence i figured that maybe there is a lose cable so i opened my case up and checked all the cabels and then tried turning it on again, miracousle my pc bootet once again without issue, but when i tried playing starcraft on it i just get into the loading screen and my pc shut of, when triying to boot again after a few failed atempts with the 1sec on 10 sec off failure, i finaly get to an error message oops etc etc 0x000021A which i look up, something about a corrupt system file or uppdate gone wrong, from here i try booting, booting in safe mode but nothing works i get the message that something went wrong while booting and it suggests restarting or advanced options, and i tried reboting several times and booting in safe mode but nothing works.

after this i figure maybe windows is corrupt enough to not even alow me to boot, so i do a clean instal of windows 10 pro, and my pc finnaly booted up again, until i tried playing a game, same old boot up storie.

so i figure maybe some part of my pc is breaking down, i pull out all but the os hard drive and try to boot, doesn't help take out my graphics card, no, take out my RAM (putting them back one at a time checking both individualy), nope.

idk if my system specs are relevent in this case bat can post if needed, would apriciate the support guys, kinda frustrated over here, first day of in 7 daysof pure hell at work so would just like to sit down and play some games today.

whyen i say pc turned on, i mean it booted up normaly i could use chrome vlc everything but play games.

What do you mean, pc "Turned On" does windows start to boot, or just a blank screen?

Could be a bad PSU. If you can't boot at all, I would say try another PSU, see if that fixed it. Maybe a program figured out your PSU was gonna die and tried to save you.

 

IF you can still turn on your PC, try to get into recovery mode (directions here: https://appuals.com/how-to-fix-error-0xc000021a-in-windows-8-and-10/)

 

If not, you maybe looking at a hardware virus (not common) or something died and Windows, for once, was trying to save you.

Yup! Good luck. Also welcome to the PC... Where if it could go wrong... It most likely will.

Thx seems to be that the psu broke down, appriciate the help, have a nice day
