Windows boot troubles

[OneZero]

Hello everyone, i just got this weird problem and i can't really figure out what's going on.
I got a friend's pc that he recently upgraded and i took the ram out of it to swap it with my pretty old pc one. Both ddr3 1333 but his kit was 2x8gb while mine was just 2x4Gb.
I swapped it out and on reboot i got a blue screen with the error saying it couldn't load \system32\wiload.efi (0xc000000e) so i reinstalled my old ram and i got the same problem.
Thinking i screwed up windows i just made a bootable usb with the windows installer to reset or reinstall it, and when i booted from it, the pc showed me a BSOD, then tried to update windows then undid the changes and now while still booting from the usb stick just let me log on to my windows instance in my ssd like nothing happend.

And it's booting with the new ram, not my old one, which is fully recognized in the bios.
Now i'm here backing up all my files from my boot drive but can't figure out what's going on.
Going to leave the specs here.

Update to this issue.
If i restart the PC without the windows bootable usb it still gives me the same screen, but if i boot with the pen in and select usb in the boot menu it lets me log into windows without problems
