Hello all!

Last weekend my computer stopped booting. It is a custom built PC that I built about 18 months ago. Ill include specs at the bottom of the post.

Last weekend it stopped booting, and went straight to a BSoD with the error code 0xc0000221. The listed kernel file that was damaged/missing would be different each time I tried to boot. The screen said that Windows 10 needed to be repaired, and to boot with installation media to do so. I tried using the Win10 USB I bought when I built the machine, and got the exact same result. I have also made a new USB and a DVD using the Microsoft installation media tool and both of those gave me the same result. I have already checked my boot order, so I know that is not the issue.

My first suspicion was that my SSD I use for Windows/other heavy use programs may have gone up, but I just tried disconnecting it from the motherboard and it still will not boot.

Any ideas would be appreciated. Thank you so much!

Specs:

MSI Gaming Z97 GAMING 5 Motherboard

Intel Core i5-4690K 3.5 GHz

EVGA GeForce GTX 970

4x G.SKILL Ripjaws Series 4GB 240-Pin DDR3 SDRAM

Samsung 850 EVO 250GB SSD

WD Blue 3TB HDD

EVGA SuperNOVA 750W Power Supply

LG Blu-Ray Burner

Samsung DVD Burner

Cooler Master Cosmos SE Case

Cooler Master Hyper 212 EVO CPU Fan

Please describe the boot sequence of this system.
FYI - systems can boot from any drive in the system before transferring control to Windows

As such, you must consider any drive that was installed when you installed Windows

 

For example, when installing Windows 7 on a new SATA drive, Windows decided to boot from the older IDE drive before transferring control to Windows on the faster drive.

I only found this out because the boot times were too slow for the new SATA drive.

 

So, the first test here (IMO) would be to try to install Windows on another drive (after disconnecting both the SSD and HDD that are currently in the system)

Disconnect BOTH cables from the current drives.

Unfortunately, there are no reliable diagnostic tests for SSD's - so the only reliable "test" is to try another drive.

 

As you can check your boot order, I presume that the motherboard is functioning normally

As booting from recovery media gets the same error, then I presume that there's a hardware error preventing the system from loading the OS into memory

 

You can also try running MemTest86 (NOT 86+) from bootable media:  http://www.memtest86.com/

That'll test the memory for you.

 

Good luck!
